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.
