INTRODUCTION
COVID-19 pneumonia was detected for the first time in the world in Wuhan, China in 2019 and has spread all over the world over time. This virus, SARS-CoV-2, enters the body and causes from an asymptomatic course to a severe pneumonia with the need for intubation probably depending on the strength of the immune system, viral load, age of the patient and comorbid diseases. Hence the virus can lead to a wide spectrum of findings, additional testing is a must to make the correct diagnosis. The sensitivity of the real-time reverse transcription–polymerase chain reaction (RT-PCR) tests used for diagnosis is variable and the use of Computed Tomography (CT) is very important for diagnosis in cases with pneumonia. (1–3) As the number of cases increased all over the world, CT findings of COVID 19 pneumonia have become better recognized and the scope of findings has expanded.(4) Total number of cases worldwide has reached 62 million by October, 2020 (5). Since the March 10, 2020; when the first case was seen in our country, CT examination was routinely performed to patients with suspicion of covid pneumonia together with the PCR testing. We think that our experience of CT findings in COVID-19 pneumonia was increased with the increasing number of cases in this timeframe. Besides, there may have been differences in the evaluation of CT examinations due to the increasing workload in the days when the number of admission was high.
In this study, it was aimed to find out the possible changes in the awareness and knowledge level of the radiology department by retrospectively re-evaluating the reports of the chest computed tomography images of patients who admitted to the emergency room with the suspicion of COVID-19.
