    Diffusion MR Imaging in Sporadic Creutzfeldt-Jakob Disease
    (2014) Pekoz, Burcak Cakir; Alkan, Ozlem; Giray, Semih; Demir, Senay; Altinkaya, Naime; 0000-0001-7526-3460; 0000-0003-1348-8167; 0000-0002-4209-9075; 0000-0002-0722-3181; AAM-4169-2021; AAM-5169-2021; AAK-9310-2021; AAH-1091-2020
    Creutzfeldt-Jakob disease (CJD) is a rare dementing disease and is thought to caused by a prion. It is characterized by rapidly progressive dementia, ataxia, myoclonus, akineticmutism and eventual death. Brain biopsy or autopsy is required for a definitive diagnosis of CJD. Diffusion-weighted imaging became an important tool for early diagnosis of CJD because of the high sensitivity. We present 59-year-old female patient diagnosed as sporadic CJD with typical MR imagings.

    Diagnostic Value of T2*-Weighted Gradient-Echo MRI for Segmental Evaluation in Cerebral Venous Sinus Thrombosis
    (2015) Altinkaya, Naime; Demir, Senay; Alkan, Ozlem; Tan, Meliha; 0000-0002-4209-9075; 0000-0003-1348-8167; 0000-0001-7526-3460; 25148696; AAK-9310-2021; AAM-5169-2021; AAM-4169-2021
    Objective: We evaluated the diagnostic value of gradient-echo (GRE) imaging in patients with "cerebral venous and sinus thrombosis" (CVST). Materials and Methods: In total, 130 thrombosed venous segment signal intensities in 45 patients with CVST were analyzed retrospectively using magnetic resonance imaging and magnetic resonance venography. Results: The T2* GRE sequence had a diagnostic value for detecting acute and subacute superior sagittal sinus (SSS) thrombosis and thrombosis of the deep veins (DVs), and cortical veins (CVs; P<.05). Conclusions: The T2* GRE sequence had a high diagnostic value for detecting both acute and subacute SSS, DV, and CV thromboses. (C) 2015 Elsevier Inc. All rights reserved.

    Prevalence of Persistent Median Artery in Carpal Tunnel Syndrome: Sonographic Assessment
    (2016) Altinkaya, Naime; Leblebici, Berrin; https://orcid.org/0000-0003-1348-8167; https://orcid.org/0000-0002-6241-268X; 26324380; AAM-5169-2021; AAM-3220-2021
    This study investigated the frequency of persistent median artery (PMA) in patients with carpal tunnel syndrome (CTS) and controls. A total of 84 CTS patient wrists, and 136 wrists of control subjects without CTS, were examined on ultrasonography (US) and color Doppler US (CDUS), and by electrophysiological evaluations. The frequency of PMA in CTS was evaluated. Of 84 CTS patient wrists, 2 (2.4 %) had a PMA (both on the right side). Of 136 control wrists, 12 (9 %) had a PMA, which was unilateral in eight (three right and five left), and bilateral in two, cases. There was no significant difference between the CTS patient and control groups with respect to the frequency of PMA (P > 0.05). There was no significant difference between the CTS patient and control groups in the frequency of PMA. We suggest that an ipsilateral PMA does not increase the risk of CTS.

    Lumbar Multifidus Muscle Changes İn Unilateral Lumbar Disc Herniation Using Magnetic Resonance Imaging
    (2016) Altinkaya, Naime; Cekinmez, Melih; https://orcid.org/0000-0003-1348-8167; https://orcid.org/0000-0001-9658-9005; 26377578; AAM-5169-2021
    To assess multifidus muscle asymmetry using the cross-sectional area (CSA) and perpendicular distance of the multifidus muscle to the lamina (MLD) measurements in patients with nerve compression due to lumbosacral disc hernia. In total, 122 patients who underwent microdiscectomy for unilateral radiculopathy caused by disc herniation, diagnosed by magnetic resonance imaging (MRI), were evaluated retrospectively. Posterolateral or foraminal disc herniation at only one disc level, the L3-4, L4-L5, or L5-S1 region, was confirmed using MRI. Subjects were divided by symptom duration: 1-30 days, (group A), 31-90 days (group B), and > 90 days (group C). There were 48 cases in group A, 26 in group B, and 48 in group C. In groups A, B, and C, the median MLD differed significantly between the diseased and normal sides (P < 0.05). The MLD increased on the diseased side with symptom duration by lumbar disc herniation. The diseased side MLD was 5.1, 6.7, and 7.6 mm in groups A, B, and C, respectively (P < 0.05). The cut-off values for the MLD measurements were 5.3 mm (sensitivity = 62.3 %, specificity = 55.5 %; P < 0.05). In groups A, B, and C, the median CSA of the multifidus muscle was not significantly different between the diseased and the normal side (P > 0.05). The MLD measurement correlated significantly with multifidus asymmetry in patients with lumbar disc herniation.
