Abstract
Introduction: The spread of the COVID-19 disease and respiratory symptoms in affected patients have increased requests for high-resolution computed tomography (HRCT) imaging. It have increased the workload and radiation exposure of employees in radiology departments.
Materials and Methods: The present descriptive-analytical study examined the number of CT scans performed between 1398 and 1402 in the affiliated hospitals of Sabzevar University of Medical Sciences.
Results: According to the graphs comparing the years 1398 to 1402, it can be seen that the highest number of requests for CT scan in these five years is related to Shahrivar 1400 with the number of 9677 requests registered in this month, which can indicate the high prevalence of the Coronavirusin this month. After that, Mordad 1400 has the second rank with 9394 requests, which to some extent reveals the fact that 1400 was a critical year in terms of the spread of the Corona pandemic and overall, the year 1400 was the worst year in terms of the spread of the Corona pandemic, which accounted for the highest spread of the virus.
Conclusion: The spread of respiratory diseases, the increase in requests for HRCT scans, and the lack of manpower in these departments cause the amount of radiation exposure to reach the limits of the body's tolerable dose and sometimes exceed this amount. Accordingly, it is recommended taking necessary measures to prevent problems that are more serious for radiology personnel at risk.
