Abdominal Hydatid Disease: Long-Term Results of Percutaneous Treatment
(Blackwell Munksgaard, 2004) Etlik, O; Arslan, H; Bay, A; Sakarya, ME; Harman, M; Temizoz, O; Unal, O
Purpose: To evaluate the effectiveness of percutaneous treatment under sonographic guidance in abdominal hydatid cysts. Material and Methods: Fifty-two hydatid cysts in 33 patients were treated using a percutaneous approach under sonographic guidance. Forty-five cysts were located in the liver, 6 in the spleen, and I in the pancreas. Forty-nine cysts were type 1, and 3 were type II. Thirty-one cysts in 15 patients were treated with puncture and aspiration of the contents, injection of hypertonic saline solution, and respiration (PAIR); 15 cysts in 14 patients were treated with puncture, aspiration of cyst contents, injection of hypertonic saline solution, drainage, and injection of sclerosing agent (PAIDS); and 6 cysts in 4 patients were treated with puncture, aspiration of cyst contents, injection of sclerosing agent, and re-aspiration (mPAIDS). Hypertonic saline or alcohol was used as a scolicidal agent. The follow-up period was between 17 and 53 months. Results: A decrease in the dimensions of the cysts, solidification of the contents, and irregularity in the walls of cysts, all of which were considered signs of cure, were found in all patients. Recurrence was observed in one case and anaphylaxis in one. Conclusion: Percutaneous treatment of abdominal hydatid cysts is a safe, easily applicable, well-tolerated, and effective method.
Brain Abscess Drainage by Use of Mr Fluoroscopic Guidance
(Amer Soc Neuroradiology, 2005) Ünal, O; Sakarya, ME; Kiymaz, N; Etlik, O; Kayan, M; Kati, I; Harman, M
We describe herein the use of MR fluoroscopic guidance in the drainage of abscess cavities. We percutaneously drained 12 brain abscesses in 11 patients. A 0.3T open MR imaging system was used. Sixteen drainages were performed in 12 abscesses. Repeat drainage was needed in three recurrences and one residual lesion. No serious complications were seen. MR fluoroscopy-guided percutaneous brain abscess drainage in an open MR imaging system is feasible.
Demonstrating the Effect of Theophylline Treatment on Diaphragmatic Movement in Chronic Obstructive Pulmonary Disease Patients by Mr-Fluoroscopy
(Elsevier Sci Ireland Ltd, 2004) Etlik, O; Sakarya, ME; Uzun, K; Harman, M; Temizoz, O; Durmus, A
Introduction: The purpose of this study was to determine the increase in diaphragmatic excursion of patients with chronic obstructive pulmonary disease (COPD) treated with theophylline by MR-fluoroscopy which is an innovative method to demonstrate effectiveness of this treatment. Materials and methods: Investigations were performed on a 0.3 T open MR unit. MR-fluoroscopy images of 30 patients with COPD were obtained before and after theophylline treatment. Diaphragmatic movement values were recorded for evaluation. Results: The response of the diaphragmatic movement in COPD patients treated with theophylline was evaluated by MR-fluoroscopy and an increase of 48% in diaphragmatic contractility was determined after the treatment. The increase in contractility was found to be parallel with respiratory function tests and clinical status. Conclusion: Diaphragmatic movement and response to the medical therapy in patients with COPD can be evaluated by MR-fluoroscopy method which can allow accurate measurements.

Mr Arthrography in Chondromalacia Patellae Diagnosis on a Low-Field Open Magnet System
(Elsevier Science inc, 2003) Harman, M; Ipeksoy, U; Dogan, A; Arslan, H; Etlik, O
Objective: The purpose of this study was to compare the diagnostic efficacy conventional MRI and MR arthrography (MRA) in the diagnosis of chondromalacia patella (CP) on a low-field open magnet system (LFOMS), correlated with arthroscopy. Subjects and methods: Forty-two patients (50 knees) with pain in the anterior part of the knee were prospectively examined with LFOMS, including T1-weighted, proton density-weighted and T2-weighted sequences. All were also examined T1-weighted MRI after intraarticular injection of dilue gadopentetate dimeglumine. Two observers, who reached a consensus interpretation, evaluated each imaging technique independently. Thirty-six of the 50 facets examined had chondromalacia shown by arthroscopy, which was used as the standard of reference. The sensitivity, specificity and accuracy of each imaging technique in the diagnosis of each stage of CP were determined and compared by using the McNemar two-tailed analysis. Results: Arthroscopy showed that 16 facets were normal. Four (30%) of 13 grade 1 lesions were detected with T1. Four lesions (30%) with T2 and three lesions (23%) with proton-weighted images were detected. Seven (53%) of 13 grade 1 lesions were detected with MRA. Grade 2 abnormalities were diagnosed in two (33%) of six facets with proton density-weighted pulse sequences, two (33%) of six facets with T1-weighted pulse sequences, in three (50%) of six facets with T2-weighted pulse sequences, in five (83%) of six facets with MRA sequences. Grade 3 abnormalities were diagnosed in three (71%) of seven facets with proton density- and T1-weighted images, five (71%) of seven facets with T2-weighted pulse sequences, six (85%) of seven facets with MRA sequences. Grade 4 CP was detected with equal sensitivity with T1-, proton density- and T2-weighted pulse sequences, all showing seven (87%) of the eight lesions. MRA again showed these findings in all eight patients. All imaging techniques were insensitive to grade 1 lesions and highly sensitive to grade 4 lesion, so that no significant difference among the techniques could be shown. Conclusion: All imaging technique studied had high specificity and accuracy in the detection and grading of CP; however, MRA was more sensitive than T1-weighted and proton density-weighted MR imaging on a LFOMS. Although the arthrographic techniques were not significantly better than T2-weighted imaging, the number of false-positive diagnosis was greatest with T2-weighted MRI. (C) 2003 Elsevier Science Inc.

Mr Fluoroscopy-Guided Transthoracic Fine-Needle Aspiration Biopsy: Feasibilitty
(Radiological Soc North America, 2003) Sakarya, ME; Unal, O; Ozbay, B; Uzun, K; Kati, I; Ozen, S; Etlik, O
The purpose of this study was to evaluate the feasibility of using an open-configuration magnetic resonance (MR) imaging system with MR fluoroscopic guidance to perform percutaneous transthoracic fine-needle aspiration biopsy in patients with lung masses. Percutaneous transthoracic aspiration biopsy in patients with lung masses. Percutaneous transthoracic aspiration biopsies were performed with MR fluoroscopic guidance in 14 patients. The masses were 2-7 cm in diameter (mean, 4.1 cm). The needle was positioned by using a free-hand technique with MR fluoroscopic guidance. The needle tip reached the target lesion, and biopsy was performed. Analysis of the biopsy specimens facilitated a specific diagnosis in all patients. Pneumothorax was noted in two patients (14%) with chronic obstructive pulmonary disease. Study results showed that the described MR fluoroscopy-guided transthoracic biopsy technique can be used safely and successfully for lung masses. MR fluoroscopy can be used to reach the target lesion easily and accurately. (C) RSNA, 2003.
Mri Findings of Hepatic Alveolar Echinococcosis
(Elsevier Science inc, 2003) Harman, M; Arslan, H; Kotan, C; Etlik, O; Kayan, M; Deveci, A
Diagnosis of liver infestation by alveolar echinococcosis (AE) is based on serologic, sonographic and computed tomography (CT) findings. Experience with magnetic resonance imaging (MRI) demonstrates that features of this disease are limited. CT and MRI findings of 14 cases with hepatic AE were compared in this report. We have described the MRI appearance of hepatic AE, which exhibits variable signal intensities on T1- and T2-weighted images. Fibrous and parasitic tissue showed low signal both on T1- and, generally, on T2-weighted images. In a few cases, a high signal on T2-weighted images may be observed, due either to central necrotic zones or to small peripheral cyst. MRI than by CT was more easily identified central necrosis. However, MRI seemed to be less effective than CT in allowing us to reach a positive diagnosis, due to its inability to show microcalcifications. In addition, MRI may not reveal small lesions. In most cases, T1-weighted images revealed more clearly than CT did the margins of the lesions and the hepatic extension, especially to hepatic veins, vena cava and perihepatic spaces.

Myelopathy Due To Intrathecal Chemotherapy - Report of Six Cases
(Lippincott Williams & Wilkins, 2005) Bay, A; Oner, AF; Etlik, O; Yilmaz, C; Caksen, H
Intrathecal chemotherapy and systemic chemotherapy are used for both prophylaxis and treatment of central nervous system disease in hematologic malignancies. However, intrathecal treatment has some adverse effects, such as arachnoiditis, progressive myelopathy and leukoencephalopathy. The authors describe six children in whom myelopathy and adhesive arachnoiditis developed after administration of intrathecal chemotherapy including methotrexate, cytosine arabinoside, and prednisolone. Urinary retention and incontinence, the main presenting complaints in all patients, developed within 12 hours after intrathecal therapy and spontaneously resolved within 7 days. Two patients were unable to walk. In these two, weakness in the lower extremities gradually recovered by I month but urinary incontinence did not improve. None of the children had sensory loss. On follow-up periodic recurrent urinary tract infection was noted in four patients. MRI findings corresponded to arachnoiditis. No response was recorded on tibial nerve somatosensory evoked potentials in all patients. Intrathecal chemotherapy, especially methotrexate, can cause spinal cord dysfunction in children with acute lymphoblastic leukemia and non-Hodgkin's lymphoma. Arachnoiditis should be kept in mind as a causative factor in recurrent urinary tract infection in patients receiving intrathecal chemotherapy.

Tuberculosis in Dialysis Patients, Single Centre Experience From an Endemic Area
(Wiley, 2004) Erkoc, R; Dogan, E; Sayarlioglu, H; Etlik, O; Topal, C; Calka, F; Uzun, K
Because of immunity defect, patients with end-stage renal disease are at increased risk of developing infections, tuberculosis (TB) in particular. The incidence of TB is higher in dialysis patients than in general population. We retrospectively reviewed the charts of dialysis patients with TB in our facility. A total of 287 dialysis patients (153 male, 134 female, 223 haemodialysis (HD), 64 continuous ambulatory peritoneal dialysis (CAPD) patients, mean age 46 +/- 15) were reviewed from October 1997 to January 2002. TB developed in 30 patients (17 male, 13 female, 24 HD and six CAPD). Thirteen patients with TB presented with fever of unknown origin (FUO) and four of them subsequently developed military lesions on chest X-ray. Nine patients had pulmonary TB (four with pleural effusions), five patients had TB lymphadenits, two patients had TB peritonitis and one patient had vertebral TB. TB was presented mostly as FUO among dialysis patients in a region under poor socio-economic conditions. In such areas with endemic TB, dialysis patients who present with FUO should be carefully evaluated for the presence of TB, and test therapy for TB should be performed in otherwise unexplained FUO.
Unusual Presentation of Infantile Hemangioendothelioma
(Wiley, 2005) Bay, A; Öner, AF; Etlik, O; Koseoglu, B; Kaya, A
Infantile hemangioendothelioma is a rare benign hepatic tumor arising from mesenchymal tissue. Most of the cases present with congestive heart failure and asymptomatic abdominal mass were before 6 months of age. We described a patient with projectile vomiting, which is quite an Unusual presentation. Following surgical resection, neither recurrence nor symptoms were seen in 2 years of follow-up.
