Abstract
Does imaging of the pelvis using a set of radiographs and computed tomography (CT) cause cancer? A computer-based simulation study using 5 different imaging and radiation dose protocols has calculated the lifetime risk of malignancy for young adults for pelvic radiographs and CT scans. The cumulative lifetime-attributable risk of cancer was 0.2% for males and 0.35% for females. This appears low but the numbers needed to harm were 952 for males and 564 for females. However, the authors have based their calculations on the linear no-threshold model, which is controversial, and a linear relationship between dose and risk may not exist.
