Radiologist-initiated double reading of abdominal CT: retrospective analysis of the clinical importance of changes to radiology reports.

Lauritzen PM, Andersen JG, Stokke MV, et al. BMJ quality & safety. 2016;25:595-603.

Investigators interpreted more than 1000 abdominal CT scans twice and found clinically significant changes on the second read in 14% of cases. The authors suggest that using expert second radiology interpretation may enhance diagnostic accuracy.
