Editorial Citation Count: 0Multiple 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]Article Citation Count: 0Topographic Radioanatomical Analysis of the Singular Canal: Computed Tomography Study(Wolters Kluwer Medknow Publications, 2024) Demir, Berin Tugtag; Koksal, Ali; Cankal, Fatih; Medical Imaging Techniques ProgramPurpose: The singular canal (SC) is where the singular nerve, a branch of the inferior vestibular nerve, which carries afferent information from the posterior semicircular canal (PSCC), passes and is important in the surgical approach of the presigmoid retrolabyrinthine. This study was carried out to evaluate the visibility of the SC on standard computed tomography (CT) images, its distance to the surrounding structures, and to investigate the variations of its anatomy and its relationship with the meatus acusticus internus.Materials and Methods: The study was carried out retrospectively using images of 194 temporal bones on temporal bone CT scans of 44 men and 53 women aged 18-65. In the study, various measurements were made, especially the presence of the SC, its length, its angle with the internal acoustic canal (IAC), and the distance between the internal acoustic pore (IAP) and the singular foramen. In addition, the presence of the high jugular bulb and PSCC dehiscence images were investigated.Results: The SC was detected in 85.1% of the analyzed images. The mean canal length was 3.93 +/- 1.22 mm, the angle between the SC and the IAC was 22.68 degrees +/- 3.60 degrees, and the distance between the SC and the IAP was 7.70 +/- 0.83 mm. While no difference was found between the sides, it was determined that the length and diameter of the SC did not differ according to gender.Conclusion: Detailed morphometric analysis of the SC and a thorough understanding of its relationship with the IAC, vestibulum, and PSCC will help to accurately define the posterior and lateral borders of the dissection for this region.Article Citation Count: 0Magnetic 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.Conference Object Citation Count: 9Modeling flexforming (fluid cell forming) process with finite element method(Trans Tech Publications Ltd, 2007) Ali Hatipoǧlu,H.; Polat,N.; Köksal,A.; Erman Tekkaya,A.; Medical Imaging Techniques ProgramIn this paper, the flexforming process is modeled by finite element method in order to investigate the operation window of the problem. Various models are established using explicit approach for the forming operation and implicit approach for the unloading one. In all analyses the rubber diaphragm has been modeled revealing that the modeling of this diaphragm is essential. Using the material Aluminum 2024 T3 alclad sheet alloy, three basic experiments are conducted: Bending of a straight flange specimen, bending of a contoured flange specimen and bulging of a circular specimen. By these experiments the effects of blank thickness, die bend radius, flange length and orientation of the rolling direction of the part have been investigated. Experimental results are compared with finite element results to verify the computational models.Article Citation Count: 1Change of frontal sinus in age of according to the international frontal sinus anatomy classification(Sage Publications Ltd, 2023) Koksal, Ali; Demir, Berin Tugtag; Cankal, Fatih; Medical Imaging Techniques ProgramBackground The radiological and surgical anatomy of the frontal sinus should be well-known in all age groups to successfully manage frontal sinus diseases and reduce the risk of complications in sinus surgery. Purpose To define frontal sinus and frontal cells according to the International Frontal Sinus Anatomy Classification (IFAC) criteria in pediatrics and adults. Material and Methods A total of 320 frontal recess regions of 160 individuals (80 pediatric, 80 adults) who underwent a computed tomography (CT) scan of the paranasal sinus (PNS) were included in the study. Agger nasi cells, supra agger cells, supra agger frontal cells, suprabullar cells, suprabullar frontal cells, supraorbital ethmoid cells, and frontal septal cells were evaluated in the CT analysis. Results The incidence rates of the investigated cells were determined to be 93.1%, 41.9%, 60.0%, 76.3%, 58.5%, 18.8%, and 0% in the pediatric group, respectively, and 86.3%, 35.0%, 44.4%, 54.4%, 46.9%, 19.4%, and 3.4% in the adult group, respectively. Considering the unilateral and bilateral incidence of the cells, agger nasi cells were highly observed bilaterally in both the pediatric group (89.87%) and the adult group (86.48%). Conclusion Our study results show that IFAC can be used as a guide to increase the chance of surgical treatment in the pediatric and adult groups and that the prevalence of frontal cells can be determined radiologically and contributes to the generation of estimations of the prevalence of frontal cells.Article Citation Count: 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]Editorial Citation Count: 0Pontine 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 Citation Count: 0A 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]Article Citation Count: 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.Article Citation Count: 0Case 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.
