Editorial Bilateral adrenal haemorrhage after blunt abdominal trauma(Ma Healthcare Ltd, 2023) Guvendi, Bulent; Koksal, Ali; Gozgec, Elif; Ogul, Hayri; Kantarci, Mecit; Medical Imaging Techniques Program[No Abstract Available]Article Citation - Scopus: 1Case Report of a Patient With Posttraumatic Perilymphatic Fistula(Sage Publications inc, 2022) Koksal, Ali; Ayyildiz, Veysel; Ogul, Hayri; Kantarci, Mecit; Medical Imaging Techniques ProgramOn a perilymphatic fistula, there is an extravasation of the perilymph fluid into the middle ear cavity. Cross-sectional imaging techniques have very important role in evaluation of inner and middle ear structures and temporal bone. While thin section CT scans can show successfully pneumolabyrinth and temporal bone fracture, high-resolution 3D volumetric MRI sequences can help to demonstrate posttraumatic ear effusion and cerebrospinal fluid fistula into inner ear or middle ear.Article Citation - WoS: 1Citation - Scopus: 1Cerebellar Developmental Venous Anomaly Causing Tinnitus and Hemifacial Spasm: a Case Report(Sage Publications inc, 2022) Ogul, Hayri; Unlu, Elif Nisa; Guclu, Derya; Koksal, Ali; Medical Imaging Techniques Program[No Abstract Available]Article Citation - WoS: 1Citation - Scopus: 1Detection of the Glenoid Bare Spot by Non-Arthrographic Mr Imaging, Conventional Mr Arthrography, and 3d High-Resolution T1-Weighted Vibe Mr Arthrography: Comparison With Ct Arthrography(Springer, 2023) Ozel, Mehmet Ali; Ogul, Hayri; Koksal, Ali; Kose, Mehmet; Tuncer, Kutsi; Eren, Suat; Kantarci, Mecit; Medical Imaging Techniques ProgramObjectivesTo determine the diagnostic accuracy of non-arthrographic MR imaging, conventional MR arthrography, and 3D T1-weighted volumetric interpolated breath-hold examination (VIBE) MR arthrography sequences as compared with a CT arthrography in the diagnosis of glenoid bare spot.MethodsA retrospective study of 216 patients who underwent non-arthrographic MR imaging, conventional MR arthrography, VIBE MRI arthrography, and CT arthrogram between January 2011 and March 2022 was conducted. The diagnostic accuracy of non-arthrographic MR imaging, direct MR arthrography, and VIBE MRI arthrography in the detection of glenoid bare spot was compared with that of CT arthrography. All studies were reviewed by 2 MSK radiologists. Interobserver agreement for MR imaging and MR arthrographic findings was calculated.ResultsSixteen of 216 patients were excluded. Twenty-three of 200 shoulders had glenoid bare spot on CT arthrographic images. The glenoid bare spot was detected in 11 (47.8%) and 7 (30.4%) patients on conventional non-arthrographic MR images and in 18 (78.3%) and 16 (69.6%) patients on conventional MR arthrograms by observers 1 and 2, respectively. Both observers separately described the bare spot in 22 of 23 patients (95.7%) on 3D volumetric MR arthrograms. Interobserver variabilities were fair agreement for conventional non-arthrographic MR imaging (kappa = 0.35, p < 0.05), moderate agreement for conventional MR arthrogram (kappa = 0.50, p < 0.05), and near-perfect agreement for 3D volumetric MR arthrogram reading (kappa = 0.87, p < 0.05).ConclusionsA 3D high-resolution T1-weighted VIBE MR arthrography sequence may yield diagnostic performance that is comparable with that of CT arthrography in the diagnosis of glenoid bare spot.Editorial Intracranial Dermoid Cyst Mimicking a Thrombosed Giant Aneurysm of the Anterior Communicating Artery(Ma Healthcare Ltd, 2022) Ogul, Hayri; Koksa, Ali; Kaya, Serhat; Kantarci, Mecit; Eren, Suat; Automotive Engineering[No Abstract Available]Article Magnetic Resonance Arthrographic Demonstration of Extension of Labral Defects in Paraglenoid Labral Cysts(Assoc Medica Brasileira, 2023) Kaya, Serhat; Ogul, Hayri; Koksal, Ali; Koru, Ahmet; Kiziloglu, Alper; Kantarci, Mecit; Medical Imaging Techniques Program; Automotive EngineeringOBJECTIVE: This study aimed to investigate the extension of labral tears associated with paraglenoid labral cysts by magnetic resonance arthrography. METHODS: The magnetic resonance and magnetic resonance arthrography images of patients with paraglenoid labral cysts who presented to our clinic between 2016 and 2018 were examined. In patients with paraglenoid labral cysts, the location of the cysts, the relation between the cyst and the labrum, the location and extent of glenoid labrum damage, and whether there was contrast medium passage into the cysts were investigated. The accuracy of magnetic resonance arthrographic information was evaluated in patients undergoing arthroscopy. RESULTS: In this prospective study, a paraglenoid labral cyst was detected in 20 patients. In 16 patients, there was a defect in the labrum adjacent to the cyst. Seven of these cysts were adjacent to the posterior superior labrum. In 13 patients, there were contrast solution leak into the cyst. For the remaining seven patients, no contrast-medium passage was observed in the cyst. Three patients had sublabral recess anomalies. Two patients had rotator cuff muscle denervation atrophy accompanying the cysts. The cysts of these patients were larger compared to those of the other patients. CONCLUSION: Paraglenoid labral cysts are frequently associated with the rupture of the adjacent labrum. In these patients, symptoms are generally accompanied by secondary labral pathologies. Magnetic resonance arthrography can be successfully used not only to demonstrate the association of the cyst with the joint capsule and labrum, but also to reliably demonstrate the presence and extension of labral defects.Editorial Multiple Oncocytomas of Bilateral Parotid Glands: a Case Report(Sage Publications inc, 2022) Aydin, Fahri; Ayyildiz, Veysel; Gozgec, Elif; Koksal, Ali; Ogul, Hayri; Kantarci, Mecit; Medical Imaging Techniques Program[No Abstract Available]Editorial Pontine Capillary Telangiectasia Mimicking Active Demyelinating Plaque in a Patient With Multiple Sclerosis(Springer-verlag Italia Srl, 2023) Koksal, Ali; Kiziloglu, Alper; Ogul, Hayri; Medical Imaging Techniques Program[No Abstract Available]Editorial A Rare Cause of Unilateral Opaque Lung: Giant Primary Myxoid Spindle Cell Liposarcoma(Ma Healthcare Ltd, 2022) Ayyildiz, Veysel; Koksal, Ali; Aydin, Yener; Ogul, Hayri; Medical Imaging Techniques Program[No Abstract Available]Editorial Rare Presentation of a Choroid Plexus Papilloma(Ma Healthcare Ltd, 2022) Yesilyurt, Mustafa; Koksal, Ali; Ogul, Hayri; Medical Imaging Techniques Program[No Abstract Available]
