Background:
Although the aim of cardiac computed tomographic angiography (CTA) is to visualize the cardiac, coronary, and great vessels, portions of noncardiac structures such as lung, mediastinum, bones and abdomen are visible on the scan. some have suggested that the scans should be evaluated in all field of view. Some other believe that reporting accidental findings can lead to unnecessary follow up and anxiety. prevalence and seriously of the findings can guided the need for reporting the accidental findings or not. The aim of our study was to evaluate the prevalence and seriously of accidental extracardiac findings on MDCT angiography of coronary arteries.
