Öğe Comparison of Different Slice Thicknesses on Chest Computed Tomography for Evaluation of COVID-19-Associated Pneumonia(Aves, 2022) Atasoy, Dilara; Cetinkaya, Nazim; Caylak, Halil; Sariismailoglu, Ragip; Atalar, Mehmet HaydarOBJECTIVE: To compare the value of chest computed tomography at 1-mm and 5-mm slice thickness in terms of computed tomography severity score and computed tomography evaluation time in the diagnosis of COVID-19. MATERIAL AND METHODS: Sixty-five patients were included in the study group who are reverse-transcription polymerase chain reaction-positive for COVID-19 and had chest computed tomography. The 1 mm and 5 mm reconstructed images were evaluated in 2 different sessions with 4-week intervals by 2 certificated general radiologists. The presence of COVID-19-related findings, COVID-19 final category, and evaluation time were recorded. Thin and thick slices were compared for these variables and inter-reader reliability calculated with the Statistical Package for the Social Sciences (SPSS) for Windows. RESULTS: There was no significant difference between the COVID-19-related findings on thorax computed tomography between 1-mm and 5-mm slices except crazy paving appearance, microvascular enlargement, and septa! thickening. The frequency of the final categories of computed tomography results was consistent between the thick and thin slices. The computed tomography assessment time was significantly lower in 5 mm slices. The inter-reader reproducibility analysis results demonstrated good and excellent reproducibility of measurements between readers for both slice thicknesses. CONCLUSION: It was found that 5-mm reconstruction thickness of chest computed tomography can be employed for the initial detec- tion of COVID-19-related findings and the final diagnostic category-related COVID-19 rather than 1-mm slices with a faster availability of results which can be beneficial on pandemic hospitals.Öğe Crossed Cerebellar Diaschisis(TURKISH NEUROLOGICAL SOC, 2018) Yildiz, Bulent; Kose, Neslihan; Atalar, Mehmet Haydar; Caylak, Halil; Yildiz, Ozlem Kayim…Öğe Thorax CT Findings in Novel Coronavirus Disease 2019 (COVID-19)(Erciyes Univ Sch Medicine, 2021) Atalar, Mehmet; Caylak, Halil; Atasoy, Dilara; Cetinkaya, Nazim; Dogan, Omer Tamer; Gul, EnesNovel coronavirus disease 2019 (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 has high mortality rates. It has become a severe pandemic worldwide. Real-time PCR testing is still the gold standard test method for the definitive diagnosis of COVID-19 despite the possibility of false negatives. Radiological imaging methods, especially computed tomography (CT), are important assistant methods in the diagnosis and management of the disease. This review presents the role of CT in COVID-19 pneumonia, its diagnostic accuracy, thorax CT findings of the disease and differential diagnosis.Öğe Thorax CT findings of temporal changes in a case with COVID-19 pneumonia(Bayrakol Medical Publisher, 2021) Atalar, Mehmet H.; Caylak, Halil; Atasoy, Dilara; Cetinkaya, Nazim; Sarlismailoglu, RagipCoronavirus disease 19 (COVID-19), which has recently become a worldwide pandemic with high mortality, causes severe pneumonia. The major routes of transmission of this disease are direct inhalation of respiratory droplets or contact with surfaces contaminated with them. Its definitive diagnosis is made by a real-time PCR test. Radiological methods, especially computed tomography (CT), play an important role in supporting the diagnosis and determining disease stage and complications. In this paper, we report the CT findings of COVID-19 pneumonia at different disease stages in a patient diagnosed with the disease, and we provide a discussion of the relevant literature.
