Introduction: The aim of the study was to investigate the effects of radiological distribution on COVID-19 clinic and prognosis and to determine the relationship between laboratory parameters and thorax CT findings. Materials and Methods: Patients with COVID-19 were evaluated retrospectively. Laboratory parameters were obtained from medical records. Ground-glass opacities (GGO) and consolidation were evaluated on thorax CT. The presence of a single lobe lesion was considered as limited while multiple lobe lesions were considered as diffuse involvement for both GGO and consolidation. Result: A total 200 patients with COVID-19 were evaluated. 178 of them (89%) were discharged, 17 patients (8.5%) were transferred to the ICU and five patients died (2.5%). The ratios of mortality and transfer to the ICU in patients with diffused GGO were significantly higher compared to patients with limited GGOs. It was observed that troponin ≥0.06 µg/L, platelet

Objective The purpose of this study was to establish the diffusion-weighted magnetic resonance imaging (DW-MRI) findings of the caudate nucleus and putamen in patients with obsessive-compulsive disorder (OCD) and to obtain new information on the etiopathogenesis of OCD, which is still unclear. Methods The study comprised 20 patients with OCDs and 20 healthy volunteers. In these cases, DW-MRI and diffusion-weighted echo-planar images (DW-EPI) at b600 and b1000 gradient values were taken and the measurements were made using the apparent diffusion coefficient (ADC) maps of each group at b600 and b1000 values from the caudate nucleus and putamen. Results When the DW-MRI examination in patients with OCD was compared with the control group, the mean ADC values in the caudate nucleus and putamen were not found to have statistically significantly changed. In addition, there were no significant differences regarding the right and left caudate nuclei and putamen ADC values at the b600 and b1000 in the patients with OCD or the control group. Conclusion There are still many unknowns about the neurobiology of OCD. When the DW-MRI examination of the patients with OCD was compared with the control group in our study, no significant difference was found between the ADC values of the caudate nucleus and putamen. Further studies are required for this present study on DW-MRI in patients with OCD to be meaningful.

Coronary artery disease is one of the most common and important health problems in the world. Early diagnosis of this disease is very important to treat before severe myocardial damage occurred. Myocardial perfusion scintigraphy (MPS) and computed tomography coronary angiography (CTCA) which evaluates regional myocardial perfusion and coronary arteries, respectively, are reliable and non-invasive methods in terms of coronary artery disease. In this study we aimed to compare MPS and CTCA based on conventional coronary angiography (CCA). Totally 60 patients were included in the study. CCA and MPS were performed to 30 patients; CCA and CTCA were performed to the rest of the patients (30 patients). Lesions were classified as mild, moderate and severe in these imaging methods. MPS and CTCA were compared with CCA by using chi-square and Fisher’s exact test. MPS and CTCA’s p values were found for left anterior descending artery (LAD) p: 0, p: 0.271; for circumflex artery (Cx) p: 0.256, p: 0.08 and for right coronary artery (RCA) p: 0.033, p: 0.271, respectively. Furthermore MPS and CTCA’s sensitivity, specificity, accuracy, positive predictive value and negative predictive value were calculated 81% to 87%; 70% to 49%; 73% to 72%; 54% to 72%; 90% to 71%, respectively. CCA results were found more concordant with MPS for LAD and RCA lesions and more concordant with CTCA for Cx lesions. It was also found that positive predictive value of MPS and negative predictive value of CTCA were significantly higher than the others. As a result, MPS and CTCA were suggested as complementary techniques for the diagnosis of coronary artery disease, not as alternatives to each other.

UNLABELLED We present a 20 year-old male patient who had prominent positional proptosis of the right eye and admitted to the hospital for tonsillectomy operation. After conventional ophthalmological examination, magnetic resonance imaging (MRI) and Tc 99m labeled erythrocyte scintigraphy were performed to confirm the diagnosis. Although it is rare to perform scintigraphy for this pathology, the visualization of intraorbital hemangioma was very obvious and we would like to present the visualization of the intraorbital hemangioma both with scintigraphy and MRI. CONFLICT OF INTEREST None declared.

Objectives A retrospective study to investigate the relationship between epicardial adipose tissue thickness (EATT) and presence of coronary artery plaque, coronary artery disease (CAD) and CAD risk factors. Methods Multidetector computed tomography (MDCT) coronary angiography images were reviewed. Left anterior decending artery, right coronary artery and left circumflex artery pericoronary EATT were measured. Demographic, clinical and CAD risk factor data were obtained from medical records. Results Patients with CAD ( n = 49) had significantly larger mean EATT than those without CAD ( n = 101). Pericoronary EATT was significantly correlated with body mass index, total cholesterol level, coronary artery calcium score, hypertension and diabetes mellitus history. Conclusions There is an association between pericoronary EATT and CAD, as well as CAD risk factors. Pericoronary EATT measurement may become a widely used, easy-to-perform method for determining CAD risk.

Portal vein aneurysm (PVA) is a rare vascular anomaly. It can be seen duo to congenital or iatrogenic event. Wide application of ultrasonography (US) and Doppler US provided increase in diagnosis of asymptomatic PVA. In this article, we aimed to present ultrasonografic findings of left portal vein aneurysm with review of literature which was diagnosed incidentally a patient with abdominal pain. ©2008, Firat University, Medical Faculty., Portal ven anevrizması nadir görülen vasküler bir anomalidir.

Immature mediastinal teratomas are rare malignant neoplasms that can metastasize and recur, are characterized by the presence of various tissues that histologically resemble embryonal structures. Computerized tomography (CT) shows the location and extent of the tumors as well as intrinsic elements including soft tissue, fat, fluid, and calcification. CT is the radiological modality choice for the diagnostic evaluation of these tumors and also combination of magnetic resonance imaging (MRI) best defines the characterisation, location and operability of tumor. In this report, we present radiological findings of immature mediastinal teratoma.©2008, Fırat Üniversitesi, Tıp Fakültesi, İmmatür mediastinal teratom, metastaz ve rekürrrens bulguları gösterebilen, nadir, malign bir neoplasm olup, histolojik olarak embriyonel dokulardan oluşan farklı bir yapıya sahiptir.

The aim of this study was to evaluate the utility of apparent diffusion coefficient (ADC) values in differentiation between solid adrenal masses. The ADC values of 73 adrenal lesions (54 benign, 19 malignant) in 69 patients were measured at b 100, 600 and 1000 gradients on diffusion-weighted magnetic resonance imaging (DW-MRI). No statistically significant difference was found between ADC values of benign and malignant adrenal masses, nonadenomatous benign adrenal masses and malignant adrenal masses, adrenal adenomas and nonadenomatous lesions, adenomas and metastases, adenomas and pheochromocytomas, metastases and pheochromocytomas. ADC values are not helpful in the differentiation between solid adrenal masses. (C) 2014 Elsevier Inc. All rights reserved.

A 35-year-old woman presented with a solitary neurofibroma in an unusual presacral location without neurofibromatosis manifesting as bilateral chronic sciatica for 2 years. She was initially considered as having a giant right ovarian mass, but was referred with a prediagnosis of solitary giant sacral nerve sheath tumor. The initial differential diagnosis was based on neuroimaging. A right-sided J incision with the extraperitoneal approach provided good exposure and handling of the tumor bed. Almost total excision without neurological deficit was possible. The histological diagnosis was neurofibroma. Benign retroperitoneal neural sheath tumors in patients without von Recklinghausen's disease are quite rare. Intrapelvic tumors are often diagnosed at a later stage. Neuroimaging is very helpful to delineate this unusual site and the extent of tumor development, and to determine the appropriate surgical intervention. A clear understanding of retroperitoneal anatomy is essential for safe removal of such tumors. Complete resection is preferred to prevent local recurrence and malignant transformation. Although root section is inevitable, neurological deficit is unlikely.
