In this study, the chest computed tomography (chest CT) findings of patients with suspected COVID-19 admitted to the
emergency department were examined, and it was evaluated whether chest CT should be performed in each patient with suspected
COVID-19. Patients with suspected COVID-19 and who had chest CT were included in the study. Swab samples were taken from the
throat and nose of the patients for RT-PCR. Chest CT was applied to the patients according to the physician's decision. A team of 5
radiologists evaluated the chest CT reports. 251 patients were included in the study. In the chest CT of 154 patients (61.4%), findings
compatible with COVID-19 pneumonia were found. The number of patients who were found to have COVID-19 by PCR test result was
138 (55.0%). The most common pneumonia finding was found to be ground glass (55.8%) Most of the patients had findings in both
lungs (25.9%). Less frequently, the right lung (23.1%) was affected. The least affected was the left lung (14.7%). The most frequently
affected part of the left lung was the lower lobe. In emergency services, the use of chest CT after the physical examination of the
patients with suspected lung involvement may be useful in the diagnosis of COVID-19.
