COVID-19 and cancer risk arising from ionizing radiation exposure through CT scans: a cross-sectional study.

Publication date: Mar 05, 2024

The surge in the utilization of CT scans for COVID-19 diagnosis and monitoring during the pandemic is undeniable. This increase has brought to the forefront concerns about the potential long-term health consequences, especially radiation-induced cancer risk. This study aimed to quantify the potential cancer risk associated with CT scans performed for COVID-19 detection. In this cross-sectional study data from a total of 561 patients, who were referred to the radiology center at Imam Hossein Hospital in Shahroud, was collected. CT scan reports were categorized into three groups based on the radiologist’s interpretation. The BEIR VII model was employed to estimate the risk of radiation-induced cancer. Among the 561 patients, 299 (53. 3%) were males and the average age of the patients was 49. 61 +/- 18. 73 years. Of the CT scans, 408 (72. 7%) were reported as normal. The average age of patients with normal, abnormal, and potentially abnormal CT scans was 47. 57 +/- 19. 06, 54. 80 +/- 16. 70, and 58. 14 +/- 16. 60 years, respectively (p-value
