H., BALTACIOĞLU F.the detection of lumbosacral transitional vertebrae (LSTV) and vertebral enumeration. Patients and Methods: Institutional review board approval was obtained. Routine lumbar magnetic resonance (MR) imaging that included sagittal cervicothoracic scout images in 972 cases were evaluated retrospectively. Six segments were created in the vertebral column with 7 lines. CA and SMA ostiums were localized in these segments. Results: Coeliac artery and SMA levels were detected more caudally in lumbarized S1 and more cranially in sacralized L5 cases compared to non-LSTV cases. Conclusion: Coeliac artery and SMA origin levels as anatomical markers are not dependable for vertebral numbering due to their wide variabilityPublication Metadata only Lomber spinal stenozda faset tropizması ve foramen çapı arasındaki korelasyon: Çok merkezli radyolojik çalışma(2022-12-10) ÇEKİÇ, EFECAN; BIYIKLI, ERHAN; HARMAN, FERHAT; SARIGÜL B., ÇEKİÇ E., BIYIKLI E., Şirinoğlu D., HARMAN F.Publication Open Access Pilocytic Astrocytoma of the Cerebellopontine Angle with cerebrospinal fluid Spread in an Adult: A Case Report(2022-12-01) KURŞUN, MELTEM; OĞUZSOY, TUBA; BOZKURT, SÜHEYLA; BAYRAKLI, FATİH; BIYIKLI, ERHAN; Bıyıklı E., Kurşun M., Oğuzsoy T., Bozkurt S., Bayraklı F.Introduction Pilocytic astrocytoma of the cerebellopontine angle (CPA) is uncommon, and its spread to the cerebrospinal fluid (CSF) at the time of diagnosis has not been reported in the literature. Case Presentation We report the case of a 33-year-old man with multifocal pilocytic astrocytoma diagnosed by magnetic resonance imaging (MRI) and confirmed by histopathological examination, and present the radiological and histopathological findings. Conclusion In the case herein reported, we observed spread of the pilocytic astrocytoma of the CPA to the CSF at the initial diagnosis, and early detection by MRI is very important regarding the treatment modality and prognosis.Publication Open Access The intensity or duration of inflammatory back pain has no impact on the detection of sacroiliitis by magnetic resonance imaging in axial spondyloarthritis(2023-06-15) BIYIKLI, ERHAN; BUĞDAYCI, ONUR; KUTLUĞ AĞAÇKIRAN, SEDA; ATAGÜNDÜZ, MEHMET PAMİR; SEVİK G., BIYIKLI E., BUĞDAYCI O., ABACAR K. Y., KUTLUĞ AĞAÇKIRAN S., ÇOLAKOĞLU ÖZKAYA Ş., EKİNCİ G., ATAGÜNDÜZ M. P.Background: Sacroiliac joint (SIJ) magnetic resonance imaging (MRI) is an established tool in the evaluation of patients with axial spondyloarthritis (axSpA). In the validation study of the ASAS classification criteria for axSpA, only 63.1% of patients had sacroiliitis on the SIJ-MRI.[1] Studies that enrolled patients with axSpA based on expert opinion reported the sensitivity of MRI between 35 to 42% in detecting sacroiliitis.[2,3] Objectives: This study aimed to evaluate the temporal relationship between ASAS defined positive MRI and the characteristics of low back pain (LBP) in axSpA. Methods: Following axSpA groups were enrolled in the study whenever an attending physician ordered an SIJ-MRI. Patients fulfilling both the Rudwaleit criteria for inflammatory back pain (IBP) and Amor criteria, patients with a previous classification with either modified New York or ASAS classification criteria.[1] A blinded rheumatologist (GS) recorded the intensity and duration of IBP using a questionnaire before SIJ-MRI. MRI appointments were based on availability. Therefore some patients did not have IBP at acquisition. Two radiologists assessed SIJ-MRIs using the ASAS/OMERACT MRI group definition of active sacroiliitis.[4] In case of discrepant reporting, a third experienced radiologist (GE) adjudicated the SIJ-MRIs. The probability of axSpA is estimated using sum scores for SpA features excluding the SIJ-MRI.[5] The correlation between an ASAS-defined positive MRI and LBP characteristics was analyzed. Results: Fifty-nine patients (32 F/27M) were included. Patient characteristics are given in Table 1. Overall, 28 of 59 patients (47.5%) had a positive SIJ-MRI defined by ASAS. The median duration of LBP was 15 (43) days and the highest intensity of LBP was felt 6.5 ± 1.2 days before the MRI appointment. At acqusition, 13 (22.0%) patients reported no LBP. There was no significant difference between the presence of LBP within 10 days prior to MRI and sacroiliitis on MRI. (p=0.6) (Sacroiliitis in 45.7% with, and 53.8% without LBP) In LBP reporting patients, pain duration and pain VAS score were 3.3 ±2.3 and 7.1 ±1.9 in patients with sacroiliitis, and 8.7 ±3.6 and 6.8 ±1.7 in patients without sacroiliitis on MRI, respectively. (p=0.48, p=0.10) Age, sex, BASDAI, CRP and calculated probability of axSpA had no correlation with the presence of sacroiliitis on MRI. Adding sacroiliitis on SIJ-MRI to axSpA probability score increased the rate of patients with a probability of >90% for axSpA from 71.2 to 83.1% but the rate of sacroiliitis on MRI was similar in all probability groups. Conclusion: These results suggest that the presence of LBP and the duration of intense pain do not affect the detected rate of sacroiliitis on SIJ-MRI in axSPA. The low prevalence of sacroiliitis in this study population implies its value as a classification tool. Further studies with larger sample sizes are needed to clarify the factors affecting the SIJ-MRI findings in axSpA patients.Publication Metadata only “Transient global amnezi” tanılı olgudauncus’ta difüzyon kısıtlaması(2023-05-11) BIYIKLI, ERHAN; SEMİZ OYSU, ASLIHAN; Melik F., BIYIKLI E., SEMİZ OYSU A.Giriş: Transient global amnezi, ani başlangıçlı anterograd amnezi ile karakterize, tekrarlayan sorgulamanın eşlik ettiği, bazen retrograd bileşenli, 24 saate kadar süren ve diğer nörolojik işlevlerden ödün vermeyen klinik bir sendromdur. Tipik olarak 50-70 yaşlarındaki hastalarda rastlanır. Prosedürel hafıza da dahil olmak üzere diğer nörolojik fonksiyonlar korunur (1). Manyetik rezonans görüntüleme (MRG), hipokampüsün değerlen- dirilmesi için tercih edilen görüntüleme yöntemidir. Standart beyin protokolünün yanı sıra, epilepsi, demans veya transient global am- nezi (TGA) gibi belirli klinik senaryolara göre hipokampal çalışmaya ayrılmış sekanslar kullanılır. TGA’nın etiyolojisi ve patofizyolojisi be- lirsizliğini korumaktadır.
