Evaluation of CT examinations structure for hospitalized patients with COVID-19

The aim of the current study was to evaluate CT-examinations structure for patients with COVID-19 at the hospital stage of treatment. The number of CT examinations and the effective dose per scan, per whole hospital treatment and for the entire period of illness were analyzed for samples of patients with various CT-stages of viral pneumonia. The results of the study indicate that the largest number of CT examinations were performed for patients with CT-4 stage;there were no significant differences between the samples of patients with CT-1,2,3 stages. Conducting more than two CT studies in COVID-19 is mainly driven by the need to assess the patient's condition dynamics. The maximum doses were determined in patients with the CT-4 stage, the minimum - with the CT-3 stage, what can be explained, first of all, by the anthropometric characteristics of individual patients. © 2021 Author(s).
