Coronary Artery Anomalies and Variations Detected in Computed Tomography Angiography
(Yuzuncu Yil Universitesi Tip Fakultesi, 2019) Gündüz, A.M.
There are many methods in the diagnosis of coronary artery diseases, and the reference method is catheter angiography. Coronary computed tomography angiography (c-CTA) is more valuable in the diagnosis of coronary artery and cardiac anomalies, plaques in the coronary artery wall, aortic dissection, myocardial bridges, osteal pathologies and coronary fistulas. In this study, we investigated the diversity and frequency of coronary artery anomalies and variations in c-CTA examinations performed in our unit. We included 700 patients who underwent c-CTA in the study. The c-CTA images and reports of the patients were retrospectively evaluated, and the diversity and frequency of coronary artery anomalies and variations were investigated. The axial images, multiplanar reconstruction, maximum intensity projection and 3D volume rendering images were examined together and coronary artery stenosis, anomalies and variations were evaluated. We detected intermediate artery in 126 patients and myocardial bridging in 87 patients. LMCA was not observed in 11 patients. Single coronary artery was observed in 3 patients. RCA showed an interarterial course between aorta and pulmonary artery in 1 patient. C-CTA is an effective method in detecting coronary artery diseases, variations and anomalies. There are studies indicating that c-CTA is superior to catheter angiography in the diagnosis of coronary artery anomalies. Coronary artery anomalies are the uncommon category of cardiac diseases. Their incidence in the community is 1-2%. Our study supports that c-CTA is an imaging method that is used in the diagnosis of coronary artery anomalies and variations and provides detailed information. © 2019, Yuzuncu Yil Universitesi Tip Fakultesi.

Idiopathic Granulomatous Mastitis and Other Types of Mastitis; Comparison of Ultrasound Findings
(Yuzuncu Yil Universitesi Tip Fakultesi, 2021) Toprak, N.; Gündüz, A.M.
Idiopathic granulomatous mastitis (IGM) is a chronic autoimmune inflammatory condition that can negatively affect patient psychology, that effective diagnostic protocols and treatment plans have not yet been established. Since the treatment protocols used differ, other causes of mastitis should be excluded. The purpose of this study was to compare ultrasonography (US) findings of IGM with type of the other mastitis (OM) to identify the imaging signs essential for a correct differential diagnosis. This retrospective study was approved by the University Ethics Committee. This study was between August 2017 and August 2018. Parenchymal distortion and no discrete mass, mass-like lesions with indistinct borders, tubular connections, duct ectasia-periductal thickening, skin thickening and presence of an abscess were evaluated in US for each breast lesion. The fifty-seven patients with IGM and 38 with OM were included in the study. The mean age was 35.2±8.4 and 43.6±12.5 years for those with IGM and OM, respectively. US showed tubular connections (43(75.4%)) with finger-like projections that tended to coalesce (P˂0.01) and mass-like hypoechoic lesions (51(89.5%)) with irregular margins in IGM. Most cases of OM, 37 (97.4%), had mass-like lesions with indistinct borders. The US findings of IGM sometimes overlap with types of OM. Although core biopsy is typically diagnostic, US findings are very useful in the differential diagnosis of IGM and OM. Especially, observation of tubular-related hypoechoic mass-like lesions may suggest IGM in the reproductive age patient with chronic mastitis. © 2021, Yuzuncu Yil Universitesi Tip Fakultesi.

The Value of Flexion Mri Acquisition in Detection of Meniscal Tears
(TIP ARASTIRMALARI DERNEGI, 2010) Gündüz, A.M.; Arslan, H.; Avcu, S.; Etlik, O.; Doǧan, A.; Ünal, O.
Aim: The efficiency of MRI of the flexed knee was studied concerning meniscal lesion staging, existence of tears and meniscocapsulary separation (MCS). Method: In our study with 50 cases, saggital TSE Pd/T2W sequences were acquired in flexion position in addition to routine MRI sequences in neutral position. Subtle or apparent tears and MCSs observed on neutral position acquisitions (NPA) were also evaluated with knee in flexion acquisitions (KFA) in order to evaluate additional diagnostic findings. Statistical evaluation was performed using Chi-square and reliability of medical diagnostic tests. Result: There was no statistically significant difference between NPA and KFA concerning meniscal lesion grading (p>0.05). There was no statistically significant difference between NPA and KFA concerning tears due to signal increase extending to the joint surface. On the other hand, KFA contributed in tears due to MCSs (28,6%). Conclusion: KFA is an applicable method in closed system MR devices, does not disrupt patient comfort and is not time consuming. Using this method, additional information can be acquired with high contrast resolution images. KFA seems to be a superior method to NPA in patients with suspected meniscal tears and especially in cases of MCS. Further studies with extended number of patients will increase the reliability of the results.
