Diagnostic accuracy of ai for opportunistic screening of abdominal aortic aneurysm in ct: a systematic review and narrative synthesis

HIGHLIGHTS

SUMMARY

    The radiation exposure associated with CT restricts its application as a screening 2 of 16 method, but CT data can be used for opportunistic AAA detection either while reporting the study or via retrospective analysis of scans with the abdominal aorta in the field of view. The reported AI sensitivity (95%) for AAA detection in noncontrast CT was higher than the AAA incidental detection sensitivity by radiologists (65%). 62.5% of included studies used a single AAA-positive CT scan to validate their algorithm, which does not allow estimation of the accuracy, specificity, and . . .
