At the authors' level 1 trauma center, postgraduate year 3 and 4 radiology residents interpret urgent overnight imaging studies, which are reviewed by attending radiologists the next morning. The goals of this study were to determine the discrepancy rate for torso computed tomography between resident radiologists' preliminary interpretations and attending radiologists' final interpretations and to identify adverse patient events secondary to the delayed diagnoses. ⋯ At the authors' institution, there was a 2.0% discrepancy rate between residents' preliminary interpretations and attending radiologists' final interpretations of overnight torso computed tomography, with a small rate of additional intervention as a result of the major discrepancies. No adverse patient effects were directly attributable to discrepant interpretations. In discrepant cases, there was a 15% disagreement rate (17 of 112) between attending radiologists, suggesting some degree of interreader variance in interpretation. In addition, this disagreement rate among attending radiologists may imply that these cases were complex. Because there is educational value in overnight call, independent radiology resident coverage should continue.

Comparative Study
Comparison of image quality and arterial enhancement with a dedicated coronary CTA protocol versus a triple rule-out coronary CTA protocol.
To compare the image quality of dedicated coronary computed tomography angiography (cCTA) to that of triple rule-out (TRO) CTA designed to evaluate the coronary arteries, thoracic aorta, and pulmonary arteries. ⋯ A TRO-CTA protocol using 95 mL of contrast can provide comparable coronary image quality and coronary vascular enhancement as compared to dedicated cCTA with 70 mL of contrast.
