(Soc Romana Ultrasonografe Medicina Biologie-srumb, 2015) Yavuz, Alpaslan; Bora, Aydin; Bulut, Mehmet Deniz; Batur, Abdussamet; Milanlioglu, Aysel; Goya, Cemil; Andic, Cagatay
Aims: To evaluate the feasibility of quantitative analysis of muscle stiffness by Acoustic Radiation Forced Impulse (ARFI) elastography over a course of graduate isometric voluntary contractions. Material and methods: The stiffness of the bilateral biceps muscle of 13 healthy volunteers was measured in real time by ARFI elastography, while the forearm was in neutral-extended position, 90 degree self-flexed positions and 90 degree self-flexed position, with altered weights ranging from 1 to 8 kg placed on flattened palmar surfaces consecutively. The determined increases in biceps muscle stiffness were measured for both arms and correlated with the loadings weights adopted at progressive trial stages. Results: The mean shear wave velocity (SWV) values of biceps muscles in a neutral position, in 90 degree flex position and 90 degree flex position with 1 to 8 kg weights on palmar surfaces were 2.162 +/- 0.302 m/sec, 3.382 +/- 0.581 m/sec, and 3.897 +/- 0.585 to 5.562 +/- 0.587 m/sec, respectively. Significant correlations between the muscle SWV values and related palmar weights and between the SWV values of right and left sides at different trial stages were identified (r=0.951 and r=0.954, respectively). A mutual propagation path of deep regions to entire areas was described to account for the distribution of increase in stiffness with increases in palmar weights. The confidence of method regarding inter-observer difference was confirmed by the correlation analyses of the results (r=0.998). Conclusions: ARFI elastography is a feasible imaging modality for quantifying the stiffness of isometrically voluntarily contracting muscles.
Anterior Hepatic Grooves Accompanied by Chilaiditi Sign: a Retrospective Radiological Analysis of a Neglected Anatomical Fact
(Springer France, 2015) Yavuz, Alpaslan; Batur, Abdussamet; Bulut, Mehmet Deniz; Bora, Aydin; Goya, Cemil; Andic, Cagatay; Olmez, Sehmus
To evaluate anterior hepatic grooves (AHGs) associated with hepato-diaphragmatic mesocolic indentations (Chilaiditi sign) and to delineate the incidence and potential clinical significance of this association. Between November 2011 and June 2014, abdominal computed tomography examinations of 2,314 patients with varied indications were retrospectively reviewed. Patients were surveyed consecutively for the Chilaiditi sign and syndrome, and cases with grooves at the antero-inferior hepatic surface enclosing the adjacent mesocolic indents were determined. The incidence of AHGs and their predominance by gender and age were determined. The potential clinical significance of AHGs associated with Chilaiditi syndrome and their possible effect on liver volume were assessed. The incidences of AHGs were similar between genders (p = .461 and p = .646) and age (p = .113 and .621, respectively) among total cohort and patients with Chilaiditi sign, respectively. There was no significant correlation between AHGs and Chilaiditi syndrome (p = .506); no efficacies of AHGs to liver volume were assessed (p = .413). The AHGs are rare adaptive changes in shape of the liver without a significant effect on liver volume. This overlooked phenomenon is likely derived from the Chilaiditi sign, but has no significant correlation with Chilaiditi syndrome. Future studies with extended series are encouraged to reveal the possible significance of this phenomenon based on concerned surgical interventions.
Assessment of Liver Volume With Computed Tomography and Comparison of Findings With Ultrasonography
(Springer, 2014) Bora, Aydin; Alptekin, Cem; Yavuz, Alpaslan; Batur, Abdussamet; Akdemir, Zulkuf; Berkoz, Mehmet
In this study, we aimed to investigate the impact of non-alcoholic hepatic steatosis on the liver volume. As investigating hepatic steatosis, we utilized computed tomography (CT) to determine the degree of steatosis and we utilized hepatobiliary ultrasonography (USG) for densitometry and correlation. As hepatosteatosis group, 35 patients over 18 years of age and whose abdominal CT scans were requested by several clinics and performed routinely were included in this study, and as control group, 40 healthy subjects without hepatosteatosis (clinically and radiologically) and correlated with hepatosteatosis group in terms of age and gender were included in this study. CT densitometry and liver attenuation index (LAI) of all individuals who participated in our study were calculated, and contrast images of patients were transferred to CT-Volume Software (Siemens Syngo Multimodality Workplace; Version VE52A). In this study, interactive and automated volume measurement techniques were used together. The volumes were measured separately in patient and control group. In this study for each stage in USG, there was found a direct correlation in terms of LAI and volume, and this correlation was statistically significant (p < 0.01). Furthermore, statistical significance between size and USG stage draws attention (p < 0.05). A significance relationship between USG stage and age could not be determined. As a result, we have reached the conclusion that CT densitometry can be used as an assistive technique along with USG to determine the degree of steatosis in the non-alcoholic fatty liver disease, and there is a positive linear correlation between the liver size and volume, and liver volume increases in the non-alcoholic fatty liver disease.
Assessment of Optic Nerve Vascularity in Healthy Eyes Using Superb Microvascular Imaging: a Preliminary Study
(Sage Publications Ltd, 2022) Batur, Abdussamet; Alpaslan, Muhammed; Ozkacmaz, Sercan; Durmaz, M. Sedat
Background Changes in optic nerve vascularity are observed in many diseases. Superb microvascular imaging (SMI) has the potential to become the method of choice for detecting microvasculature in the optic nerves. Purpose To evaluate optic nerve vascularity in healthy individuals through power Doppler sonography (PDUS) and SMI. Material and Methods Twenty-seven healthy patients with 54 eyes were prospectively evaluated. The duration of the examination for optic nerve vascularity lasted until the posterior ciliary artery blood supply was observed in PDUS and SMI. The visibility of vascularity, as well as the ratio of the vascular structures to the optic nerves (vascular index [VI]), was evaluated. Results Fifty-four eyes were evaluated from a total of 27 patients (mean age = 49.0 +/- 19.42 years). The VI value for the right optic nerve was 29.58 +/- 4.00 while for the left optic nerve, it was 31.21 +/- 3.52. Vascularity was clearly observed in both eyes (n = 54) in all 27 cases in the evaluation performed with the SMI technique. However, with the power Doppler examination, vascular flow was not observed in 14 right eyes and in 10 left eyes within the specified timeframe. Conclusion The results indicate that imaging of vascular structures can be done faster and better with SMI than PDUS examination. The normal VI values may provide important information about the blood supply of the optic nerve, which is of relevance in orbital pathologies and many systemic conditions.
The Association Between Retinal Nerve Fibre Layer Thickness and Corpus Callosum Index in Different Clinical Subtypes of Multiple Sclerosis
(Springer-verlag Italia Srl, 2017) Cilingir, Vedat; Batur, Muhammed; Bulut, Mehmet Deniz; Milanlioglu, Aysel; Yilgor, Abdullah; Batur, Abdussamet; Tombul, Temel
The objective of this paper is to evaluate the association between physical disability in multiple sclerosis (MS) patients, the thickness of the retinal nerve fibre layer (RNFL) and corpus callosum volumes, as expressed by the corpus callosum index (CCI). This study was based on a cohort of 212 MS patients and 52 healthy control subjects, who were age and gender matched. The MS patients included 144 women and 177 relapsing-remitting MS (RRMS) patients. Peripapillary and volumetric optical coherence tomography (OCT) scans of the macula were performed using spectral-domain OCT technology. All magnetic resonance imaging (MRI) scans were performed using 1.5-T systems. CCI and RNFL were lower in MS than healthy control subjects (0.341 versus 0.386, p < 0.01 and 92.1 versus 105.0, p < 0.01). In addition, CCI correlated with RNFL (r = 0.464, p < 0.01). This was also true for the subgroup of patients with no history of optic neuritis (ON). There is a correlation between the thickness of the RNFL and CCI values in MS patients with no history of ON, which suggests that OCT might be a suitable marker for neurodegeneration in MS clinical trials.
Budd-Chiari Syndrome and Renal Arterial Neurysms Due To Behcet Disease: a Rare Association
(African Field Epidemiology Network-afenet, 2015) Batur, Abdussamet; Dorum, Meltem; Yuksekkaya, Hasan Ali; Koc, Osman
Behcet's disease is a multisystemic vasculitis of unknown etiology with a chronic relapsing course. Vasculitis in Behcet's disease with predominant vascular involvement is the only vasculitis that affects both arteries and veins of any size. Involvement of the renal artery and inferior vena cava is rare among the arteries and veins, respectively. When disease affect the veins, it is in the form of thrombosis. Arterial complications include aneurysms, stenosis and occlusions. Both rupture of arterial aneurysm and occlusion of suprahepatic veins, causing Budd-Chiari syndrome, are associated with a high mortality rate. Vascular involvement is more common in male patients than in female patients. Men and patients with a younger age of onset present with a more severe prognosis. In this case report, we describe a very rare cause of intrarenal arterial aneurysm's rupture with previous Budd-Chiari syndrome due to Behcet's disease and successful angiographic embolization of actively bleeding aneurysm.
A Case of Sarcoidosis With Pleural Involvement
(Wiley, 2018) Sunnetcioglu, Aysel; Sertogullarindan, Bunyamin; Batur, Abdussamet; Bayram, Irfan
Sarcoidosis is a chronic, multisystem inflammatory disorder of unknown etiology that is characterized by noncaseating granulomas. Although lung involvement is common in sarcoidosis, pleural involvement is rare. Pleural involvement may manifest as a pleural effusion, pneumothorax, pleural thickening and nodules, hydropneumothorax, hemothorax, or chylothorax. Here, we describe a case of sarcoidosis with pleural nodular thickening.
Colon Cancer Presented With Sigmoid Volvulus: a Case Report
(Elsevier Sci Ltd, 2015) Aras, Abbas; Kiziltan, Remzi; Batur, Abdussamet; Celik, Sebahattin; Yilmaz, Ozkan; Kotan, Cetin
Introduction: Sigmoid volvulus is the most prevalent type of colonic volvulus. Colon cancer is seen less where sigmoid volvulus is common, so it is rare to see that colon cancer is synchronous with sigmoid volvulus. PRESENTATION OF CASE: We would like to present a case of sigmoid volvulus caused by colon cancer in a male patient aged 80 who was referred to the hospital with toxaemic shock presentation. DISCUSSION: Sigmoid cancer can be presented as sigmoid volvulus to the emergency department. In intestinal obstruction early diagnosis is of crucial importance. Computarized tomography is a diagnosis tool that should be preferred both in the diagnosis of obstruction and in detecting its cause, localisation, degree and complications. CONCLUSION: When surgery is performed due to the urgent colonic obstruction in colonic volvulus diagnosed patients, a colon tumour should be considered in the same column loops or in the distal colon. We believe that CT is the method that should be preferred in large-bowel obstruction suspected patients. (C) 2015 The Authors. Published by Elsevier Ltd.
A Comparative Evaluation of Cataract Classifications Based on Shear-Wave Elastography and B-Mode Ultrasound Findings
(Springer international Publishing Ag, 2019) Ozgokce, Mesut; Batur, Muhammed; Alpaslan, Muhammed; Yavuz, Alpaslan; Batur, Abdussamet; Seven, Erbil; Arslan, Harun
In this study, a comparison is made of the findings of B-mode ultrasound and ultrasound elastography with the Lens Opacities Classification (LOCS) grade in patients with senile cataracts. A total of 74 patients with cataracts and 32 age-matched healthy volunteers as the control group were evaluated in the departments of ophthalmology and radiology between 2016 and 2017. In the patient group, cataracts were graded according to LOCS, and B-mode sonographic appearance and elasticity measurements were recorded, after which the cataract grade and sonoelastography/B-mode ultrasound findings were compared using statistical methods. Among the 74 patients with cataracts, 38 were females (51.4%) and 36 were males (48.6%), and the mean age was 62.05 +/- 7.95 (43-78) years. A Chi-square test revealed a significant relationship between ultrasound echogenicity of cataract and grade of cataract (p < 0.005). The ultrasound elastography revealed a mean shear-wave velocity of 2.90 m/s +/- 0.371 (2.13-3.53) among patients with grade 3 cataracts, 3.1 m/s +/- 0.45 (2.26-3.98) among patients with grade 4, 3 m/s +/- 0.58 (2.35-4.60) among patients with grade 5 and 3 m/s +/- 0.528 (2.31-4.50) among patients with grade 6 cataracts, and 3 m/s +/- 0.258 (2.36-3.58) among the normal subjects. No statistically significant difference was noted in the analysis of variance (p > 0.005). While cataract grade and B mode echogenicity were directly proportional, there was no significant difference in lens elasticity.
Comparison of Computed Tomography Densitometry and Shear Wave Elastography Velocity Measurements for Evaluation of the Liver Volume in the Nonalcoholic Fatty Liver Disease
(E-century Publishing Corp, 2016) Bulut, Mehmet Deniz; Ozdemir, Hayrullah; Bora, Aydin; Yavuz, Alpaslan; Arslan, Harun; Batur, Abdussamet; Ozgokce, Mesut
Purpose: The aim of the present study is to evaluate and compare the values of velocities measured by the shear wave elastography (SWE), and those of the liver attenuation index (LAI) determined by the computerized tomography (CT) densitometry, in the nonalcoholic fatty liver disease (NAFLD). In other words, we aimed to compare the values of density measured by CT and the stiffness determined by elastography, in the liver steatosis. In addition, it is to investigate the effect of NAFLD on the liver volume. Materials and methods: Forty five cases with hepatosteatosis who had undergone abdominal CT and 50 individuals who did not exist with fatty liver clinically and radiologically, were investigated by ultrasonography (US) and SWE. The liver and spleen attenuation values were then measured in the images of non-contrast CT, and the LAI indices were calculated. Contrast images of abdomen were processed by the CT-Volume software and measurements of liver volume were performed using the interactive and automatic liver segmentation techniques together. Values of the liver volume, LAI, liver dimensions, and the shear wave velocities were determined and recorded in the patients with hepatosteatosis and controls; statistical comparisons were performed then. Results: In the nonalcoholic fatty liver, the mean value of velocity measured by SWE was found to be 1.08 (+/- 0.11) m/s, and that of LAI measured by CT densitometry was 13.68 (+/- 10.6). No correlation was observed between these two parameters (P>0.05). A high statistically significant difference between the patient and control groups in terms of the liver volume, LAI values and liver size has been observed (P<0.01). Direct correlations existed between the liver volume and LAI values, and the grades in US, and highly significant differences were determined (P<0.01). The mean values of the liver volume in the patient and control groups were determined to be 1917.4 (+/- 425.9) cm(3) and 1311.4 (+/- 241.4) cm(3), respectively. A high statistically significant difference between the groups in terms of liver volumes has been observed (P<0.01). Conclusion: In our study, we determined no correlation between the values of velocity measured by SWE, and the values of LAI measured by CT densitometry, in the NAFLD (P>0.05). This result indicates that there is no relation between the degree of stiffness evaluated by SWE, and the attenuation values measured by CT densitometry, in the non-alcoholic fatty liver. The liver volume was found to increase in NAFLD. We concluded that the CT densitometry can be used as an auxiliary technique associated with the US, in determining the degree of steatosis in NAFLD.
Contribution of Diffusion Weighted Mri To Diagnosis and Staging in Gastric Tumors and Comparison With Multi-Detector Computed Tomography
(Assoc Radiology & oncology, 2017) Arslan, Harun; Ozbay, Mehmet Fatih; Calli, Iskan; Dogan, Erkan; Celik, Sebahattin; Batur, Abdussamet; Kotan, Mehmet Cetin
Background. Diagnostic performance of Diffusion-Weighted magnetic resonance Imaging (DWI) and Multi-Detector Computed Tomography (MDCT) for TNM (Tumor, Lymph node, Metastasis) staging of gastric cancer was compared. Patients and methods. We used axial T2-weighted images and DWI (b-0,400 and b-800 s/mm(2)) protocol on 51 pre-operative patients who had been diagnosed with gastric cancer. We also conducted MDCT examinations on them. We looked for a signal increase in the series of DWI images. The depth of tumor invasion in the stomach wall (tumor (T) staging), the involvement of lymph nodes (nodal (N) staging), and the presence or absence of metastases (metastatic staging) in DWI and CT images according to the TNM staging system were evaluated. In each diagnosis of the tumors, sensitivity, specificity, positive and negative accuracy rates of DWI and MDCT examinations were found through a comparison with the results of the surgical pathology, which is the gold standard method. In addition to the compatibilities of each examination with surgical pathology, kappa statistics were used. Results. Sensitivity and specificity of DWI and MDCT in lymph node staging were as follows: N1: DWI: 75.0%, 84.6%; MDCT: 66.7%, 82%;N2: DWI: 79.3%, 77.3%; MDCT: 69.0%, 68.2%; N3: DWI: 60.0%, 97.6%; MDCT: 50.0%, 90.2%. The diagnostic tool DWI seemed more compatible with the gold standard method (surgical pathology), especially in the staging of lymph node, when compared to MDCT. On the other hand, in T staging, the results of DWI and MDCT were better than the gold standard when the T stage increased. However, DWI did not demonstrate superiority to MDCT. The sensitivity and specificity of both imaging techniques for detecting distant metastasis were 100%. Conclusions. The diagnostic accuracy of DWI for TNM staging in gastric cancer before surgery is at a comparable level with MDCT and adding DWI to routine protocol of evaluating lymph nodes metastasis might increase diagnostic accuracy.

(Springer Japan Kk, 2018) Arslan, Harun; Yavuz, Alpaslan; Ilgen, Ferda; Aycan, Abdurrahman; Ozgokce, Mesut; Akdeniz, Huseyin; Batur, Abdussamet
The aim of the present study was to quantify the stiffness of the median nerve (MN) at the carpal tunnel inlet by acoustic radiation force impulse (ARFI) elastography and to evaluate whether ARFI can be used in diagnosis and staging of carpal tunnel syndrome (CTS). Sonographic examinations of 96 wrists in 50 patients were included in the study. The cross-sectional area and stiffness of the MN were quantitatively measured by B-mode ultrasonography (USG) and ARFI. The findings of CTS were assigned to four groups: (I) normal (n = 21), (II) mild (n = 39), (III) moderate (n = 38), and (IV) severe (n = 19). The differences between CTS patients and controls and the differences in electrodiagnostic tests among subgroups were statistically compared. ROC analysis was performed to determine the cut-off values between subgroups. Bilateral CTS was present in 46 patients (92 wrists) and unilateral CTS in four patients. Of the 96 nerves in the 50 symptomatic "idiopathic CTS" patients (48 women, 2 men; mean age 45.9 years, range 23-73 years), 39 (40.4%) were mild, 38 (39.8%) were moderate, and 19 (19.8%) were severely affected. When compared to controls, MN stiffness was significantly higher in the CTS group (P < 0.001); furthermore, it was higher in the severe or extreme severity group than the mild or moderate severity group (P < 0.001). A 3.250 m/s cut-off value on ARFI revealed sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 81, 82, 95.1, 50, and 82%, respectively. The MN stiffness measured by ARFI elastography is significantly higher in patients with CTS then in controls. ARFI elastography appears to be a highly efficient imaging modality for the diagnosis and staging of these patients.
Hepatic Artery Pseudoaneurysm: Delayed Presentation After a Blunt Trauma
(int Scientific information inc, 2015) Batur, Abdussamet; Yavuz, Alpaslan; Toktas, Osman; Bora, Aydin; Bulut, Mehmet Deniz
Background: Ruptured hepatic artery pseudoaneurysm is a rare condition that is life-threatening if not diagnosed and treated rapidly. We present a case of a spontaneously ruptured hepatic artery pseudoaneurysm that occurred after a blunt trauma, and provide a review of the current literature on this topic. This case study demonstrates a spontaneously ruptured hepatic artery pseudoaneurysm which emerged following a blunt trauma and it also presents current literature studies on the topic. Case Report: A man at the age of 34 years with blunt trauma dating back to 1.5 month was admitted to the emergency department of a hospital with hematemesis and epigastric tenderness. He also had a duodenal ulcer, blood in the gastric lumen and a large pseudoaneurysm that developed from the left hepatic artery. Soon after the diagnosis, the patient worsened and underwent distal gastrectomy and cholecystectomy that included removing the bleeding aneurysm. Conclusions: Ruptured hepatic artery pseudoaneurysm stands as a deadly condition which has to be diagnosed and managed as soon as possible. Physicians need to take aneurysms of abdominal arteries into consideration after routine diagnostic practises as long as the cause of gastrointestinal haemorrhage is unidentified.

(2017) Bozan, Nazim; Kıroğlu, Ahmet Faruk; Kundi, Pınar; Özkan, Hüseyin; Turan, Mahfuz; Arslan, Ayşe; Batur, Abdussamet
Amaç: Kronik süpüratif otitis media (KSOM) tanısı alan ve ameliyat olmuş ve rutin temporal kemik tomografisine tabi tutulan hastaların verilerini retrospektif olarak tarayarak, KSOM cerrahisi öncesi rutin bilgisayarlı tomografi (BT) taramalarının etkinliğini değerlendirmektir. Gereç ve Yöntem: Kronik süpüratif otitis media tanısı konulan ve opere edilen 42 hastanın intraoperatif bulguları ve preoperatif temporal BT bulguları retrospektif olarak değerlendirildi. Bulgular: Operasyon sırasında hastaların 23'ünde (%54,76) kolesteatom gözlendi. Preoperatif BT ile bu hastaların 21'inde kolesteatom varlığı doğru tahmin edildi. Kolesteatom saptamada BT; %91,30 (güvenlik aralığı: %71,96-%98,93) duyarlılık ve %78,95 (güvenlik aralığı: %54,43-%93,95) özgüllük oranına sahipti. İntraoperatif ossiküler zincir hasarı 32 (%76,19) hastada gözlendi ve bu hastaların 27'sinde BT ile preoperatif dönemde kemikçik hasarı tespit edilmişti. Kemikçik hasarını tespit etmede BT; %84,38 (güvenlik aralığı: %67,21-%98,93) duyarlılık ve %80 (güvenlik aralığı: %44,39-%97,48) özgüllük oranına sahip olarak bulundu. Sonuç: Çalışmamızda, preoperatif dönemde çekilen BT'nin cerrahi tedavi karar sürecinde ve cerrahi sırasında yardımcı olabilecek kıymetli bilgiler verdiğini ve bu nedenle KSOM hastalarında BT'nin rutin olarak değerlendirilmesi gerektiğini düşünüyoruz.
Magnetic Resonance Imaging Features of Idiopathic Granulomatous Mastitis: a Retrospective Analysis
(Kowsar Publ, 2016) Poyraz, Necdet; Emlik, Ganime Dilek; Batur, Abdussamet; Gundes, Ebubekir; Keskin, Suat
Background: Granulomatous mastitis is a rare and benign inflammatory breast disease that may clinically and radiologically mimic breast cancer. Objectives: The aim of this study was to evaluate the features of idiopathic granulomatous mastitis (IGM) on breast magnetic resonance imaging (MRI) with mammographic and sonographic findings. Patients and Methods: A retrospective analysis was conducted on 20 patients with IGM who had been diagnosed by needle core or excisional biopsy at a single institution between 2006 and 2012. All of the patients underwent MRI for suspicious breast findings prior to biopsy. MRI examinations were performed on a 1.5 T scanner. The MRI findings were evaluated in accordance with the breast imaging-reporting and data system (BI-RADS) MRI lexicon established by the American College of Radiology. Results: MRI detected a total of 29 lesions in the 20 patients. Fourteen of these lesions were seen as mass enhancements, with the remaining 15 identified as non-mass enhancements (NMEs). The median size of all lesions was 3.6 cm (range, 0.7-6.7 cm). The most frequently observed features were masses with a round shape (9 out of 14, 64%), smooth contour (11 out of 14, 78%), and a rim enhancement pattern (10 out of 14, 71%). The most common features of the 15 NME lesions were segmental distribution (6 out of 15, 40%) and heterogeneous enhancement patterns (8 out of 15, 53%). The time-intensity curves of the dynamic studies showed benign type one signal intensity (persistent enhancement pattern) in the majority of lesions (10 out of 20, 50%). Conclusion: Our study suggests that breast MRI findings of IGM have a wide spectrum. Rim enhancement patterns are frequently seen on contrast enhanced images, but the imaging findings are nonspecific and cannot be used definitively to distinguish between benign and malignant lesions.
Measurement of Spleen Stiffness by Shear-Wave Elastography for Prediction of Splenomegaly Etiology
(Lippincott Williams & Wilkins, 2019) Batur, Abdussamet; Alagoz, Sumeyra; Durmaz, Fatma; Baran, Ali Irfan; Ekinci, Omer
Objective The aim of this study was to evaluate the reproducibility of measurement of spleen stiffness at the time of the initial detection of splenomegaly, whether it is found incidentally or not, in determining the etiology of splenomegaly. Methods The pathologies that brought about the diffuse splenomegaly were evaluated in 3 main groups as follows: hepatoportal, myeloproliferative, and infectious causes. In addition, 17 healthy control patients were recruited. All patients were examined with acoustic radiation force impulse imaging with VTQ. Results The difference between the splenic parenchymal elasticity values in the hepatoportal group (3.27 +/- 0.36 m/s), in the myeloproliferative disease group (2.98 +/- 0.33 m/s), in the infectious disease group (2.44 +/- 0.21 m/s), and in the control group (2.08 +/- 0.19 m/s) was found to be statistically significant (P = 0.001). The intraclass correlation coefficient for shear wave velocity measurement between hepatoportal causes and myeloproliferative causes was 71.2% (95% confidence interval [CI], 54.9%-87.4%), between hepatoportal causes and infective causes was 99.7% (95% CI, 98.6%-100.0%), and between myeloproliferative causes and infective causes was 83.3% (95% CI, 68.8%-97.9%). In the same patient groups, spleen volumes were measured as 64.08 +/- 9.66, 78.18 +/- 18.52, and 51.57 +/- 7.44 cm(2), respectively; in the control group, it was 26.75 +/- 6.57 cm(2). The difference between spleen volumes was found to be statistically significant (P = 0.001). Conclusions Distinguishing the causes of splenomegaly is important because the disorders require different management strategies. In diseases that cause splenomegaly, tissue content may change according to pathogenesis. Such changes in the spleen are mechanical properties that can be quantified by elastography.
