A study of 3.0-Tesla lumbar MRI comparing skeletal, neural, and vascular markers(ELSEVIER SCIENCE INC, 2014) TÜRELİ, DERYA; Tureli, Derya; Ekinci, Gazanfer; Baltacioglu, FeyyazPurpose: This study aimed to determine the reliability of the iliolumbar ligament (ILL), 12th costa, aortic bifurcation (AB), Tight renal artery (RRA), and conus medullaris (CM) for numbering of vertebral segments. Subjects and methods: Five hundred five patients underwent routine lumbar MRI examinations including a cervicothoracic sagittal scout and T1 and T2-weighted sagittal and axial turbo spin echo images. Images were evaluated by two radiologists separately. Results: The identifiability of ILL and 12th costa were 85.7% and 48.1%. AB, RRA, and CM were located more caudally in lumbarized S1 and more cranially in sacralized L5 cases. Conclusion: Landmarks suggested by previous studies are not reliable alternatives to cervicothoracic scout images due to wide ranges of distribution and inconsistencies in identification.

O., Ekinci G., Afsar N. E. Y., Cavdar S.Publication Metadata only Utility of Interobserver Agreement Statistics in Establishing Radiology Resident Learning Curves During Self-directed Radiologic Anatomy Training(ELSEVIER SCIENCE INC, 2015) BALTACIOĞLU, FEYYAZ; Tureli, Derya; Altas, Hilal; Cengic, Ismet; Ekinci, Gazanfer; Baltacioglu, FeyyazRationale and Objectives: The aim of the study was to ascertain the learning curves for the radiology residents when first introduced to an anatomic structure in magnetic resonance images (MRI) to which they have not been previously exposed to. Materials and Methods: The iliolumbar ligament is a good marker for testing learning curves of radiology residents because the ligament is not part of a routine lumbar MRI reporting and has high variability in detection. Four radiologists, three residents without previous training and one mentor, studied standard axial T1- and T2-weighted images of routine lumbar MRI examinations. Radiologists had to define iliolumbar ligament while blinded to each other's findings. Interobserver agreement analyses, namely Cohen and Fleiss kappa statistics, were performed for groups of 20 cases to evaluate the self-learning curve of radiology residents. Results: Mean kappa values of resident-mentor pairs were 0.431, 0.608, 0.604, 0.826, and 0.963 in the analysis of successive groups (P <.001). The results indicate that the concordance between the experienced and inexperienced radiologists started as weak (kappa <0.5) and gradually became very acceptable (kappa >0.8). Therefore, a junior radiology resident can obtain enough experience in identifying a rather ambiguous anatomic structure in routine MRI after a brief instruction of a few minutes by a mentor and studying approximately 80 cases by oneself. Conclusions: Implementing this methodology will help radiology educators obtain more concrete ideas on the optimal time and effort required for supported self-directed visual learning processes in resident education.Publication Open Access Atypical presentations of eosinophilic fasciitis(MEDKNOW PUBLICATIONS & MEDIA PVT LTD, 2016) SALMAN, ANDAÇ; Ergun, Tulin; Seckin, Dilek; Salman, Andac; Ocak, Esra Sarac; Yucelten, Ayse Deniz; Direskeneli, Haner; Demirkesen, Cuyan; Ekinci, Gazanfer; Bayik, MahmutEosinophilic fasciitis is an uncommon connective tissue disease that may mimic and overlap with other sclerosing disorders such as morphea and lichen sclerosus. Herein, we report four patients (two men and two women, aged 16-64 yeas) with eosinophilic fasciitis. There was overlap with both morphea and lichen sclerosus in 2 patients and with morphoea alone in 1 patient. Magnetic resonance imaging (MRI) was used for diagnosis in three patients and for assessing treatment response in one patient. Eosinophilic fasciitis may co-exist with morhoea and lichen sclerosus. In view of the overlapping clinical and histopathological features of these disorders, MRI may be helful in delineating the conditions by detecting involvement of fascia.Publication Metadata only Progressive dysarthria and dysphagia in an otherwise healthy girl(PERGAMON-ELSEVIER SCIENCE LTD, 2013) EKİNCİ, GAZANFER; Koytak, Pinar Kahraman; Alibas, Hande; Ekinci, Gazanfer; Uluc, KayihanPublication Metadata only The effectiveness of ultrasonography and ultrasonographic elastography in the diagnosis of carpal tunnel syndrome and evaluation of treatment response after steroid injection(ELSEVIER IRELAND LTD, 2018) EKİNCİ, GAZANFER; Asadov, Ruslan; Erdal, Ayse; Bugdayci, Onur; Gunduz, Osman Hakan; Ekinci, GazanferPurpose: To evaluate if there is a place for ultrasonography (US) and ultrasonographic elastography (UE) in the diagnosis and follow up of carpal tunnel syndrome treatment. Materials and methods: The study was performed on 25 patients (study group) and 17 healthy volunteers (control group). Measured US and UE criteria were median nerve area (MNA), proximal median nerve area (pMNA), difference between MNA and pMNA (dMNA) and strain values of carpal tunnel content (CTC) and median nerve (MN). Patients in the study group were also evaluated using the Boston questionnaire, Visual Analogue Scale (VAS) and nerve conduction studies. Thirty-three wrists in 23 patients received steroid injections on the same day. Patients were re-evaluated 6 weeks after steroid injection. To establish a cut off value for MNA, ROC Curve analysis was used. Results: Mean MNA and dMNA values in the control group were significantly lower than in the study group (7.33 +/- 1.31 vs. 15.44 +/- 5.10; p = < 0.05 and 1.58 +/- 0.75 vs. 8.91 +/- 4.93; p = 0.00 respectively). Median nerve and CTC strain indices were significantly higher in the control group (p = 0.00 and p = 0.036). Decrease in MNA and dMNA values after treatment was meaningful (p = 0.00). While there was no significant change in MN elasticity, mean CTC strain index of the study group (4.680 +/- 1.664) decreased significantly after treatment (3.621 +/- 1.054 p = 0.002). This decrease in the CTC index was more pronounced in patients who benefited from treatment (p = 0.001). Conclusion: US and UE can be useful in the diagnosis of CTS and its response to treatment, if used together with clinical and electroneurophysiological tests.Publication Open Access Cervical-Intracranial Atherosclerosis and Serum Uric Acid Level Association in Acute Stroke(GAZI UNIV, FAC MED, 2020-03-01) EKİNCİ, GAZANFER; Suer, Devran; Midi, Ipek; Ekinci, GazanferObjective: We aimed to identify whether high uric acid levels were associated with atherosclerotic intracranial/extracranial arterial stenosis and atrial fibrillation (AF) and to determine if serum uric acid (SUA) levels were an independent risk factor. Methods: One hundred seventy-four patients who presented with acute stroke within 24 hours of onset and were admitted to our hospital between December 2016 and September 2017 were included in the study. Bamford classification was used for Stroke classification. The degree of vascular stenosis was classified as lumen contour irregularity, mild, moderate and severe stenosis using the The North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria. Results: The average age of 174 patients was 69 +/- 12.7 years. Elevated serum uric acid levels were found in 66 patients. The mean SUA level was 7.33 +/- 1.02 mg/dL in these patients. Thirty-six patients were examined with AF and 14 of these patients had high SUA levels. It was found that high SUA levels were mostly related with lacunar infarct (LACI) and partial anterior circulation infarct (PACI), respectively. High SUA levels were seen more commonly in the anterior circulation, especially in the extracranial part of the carotid artery, but this was not statistically significant (p>0.05). We found a statistically significant relation between high SUA levels in moderate and severe stenosis of the extracranial portion of the posterior circulation in women (p=0.01). There was a relationship between atrial fibrillation and extracranial atherosclerosis of the anterior circulation as contour irregularity and moderate stenosis (p=0.05). Conclusions: In our study, it was found that high SUA levels were related to LACI and PACI, respectively. Further studies with larger groups are needed.Publication Metadata only Bilateral agenesis of arcuate fasciculus demonstrated by fiber tractography in congenital bilateral perisylvian syndrome(ELSEVIER SCIENCE BV, 2015) EKİNCİ, GAZANFER; Kilinc, Ozden; Ekinci, Gazanfer; Demirkol, Ezgi; Agan, KadriyeCongenital bilateral perisylvian syndrome (CBPS) is a type of cortical developmental abnormality associated with distinctive clinical and imaging features. Clinical spectrum of this syndrome is quite heterogeneous, With different degrees of neurological impairment in affected individuals. High-definition magnetic resonance imaging (MRI) has a great importance in revealing the presence of CBPS, but is limited in elucidating the heterogeneous clinical spectrum. The arcuate fasciculus (AF) is a prominent language tract in the perisylvian region interconnecting Broca and Wernicke areas, and has a high probability of being affected developmentally in CBPS. Herein, we report a case of CBPS with investigation of AF using diffusion tensor imaging (DTI) and fiber tractography in relation to clinical findings. We postulated that proven absence of AF on DTI and fiber tractography would correlate with a severe phenotype of CBPS. (C) 2014 The Japanese Society of Child Neurology. Published by Elsevier B.V.
