Diagnostic errors remain an inevitable occurrence during abdominopelvic CT (APCT) interpretation, despite advances in imaging technology. The main cause of error is failure to identify a lesion (i.e. perceptual error) and failure to recognize a finding's significance (i.e. interpretive or cognitive error). Awareness and understanding of the causes of errors can reduce their occurrence and may lead to a reduction in morbidity and mortality. This pictorial essay highlights various causes of error in interpreting APCT scans and briefly discusses possible solutions for minimizing these errors.
