PURPOSE: The aim of this study was to evaluate ECG-gated whole chest CTA as a routine triage tool for @entity1 with acute @entity662 . MATERIAL AND METHODS: Whole chest CTA with retrospective ECG-gating was performed in 30 @entity1 with acute atypical @entity662 . The ten main segments of the coronary arteries, the pulmonary arteries, the aorta, and the myocardium (function, morphology) were independently analyzed by a resident and two senior radiologists. The inter-observer agreement between resident and senior radiologists was calculated. A final diagnosis was determined by consensus. RESULTS: Thirty @entity1 were included. The coronary artery segments, myocardium and pulmonary arteries were considered analyzable in 84%, 90% and 97% of cases respectively. A final diagnosis for the cause of @entity158 was retained in 19 @entity1 : significant @entity3979 (5), @entity358 (5), aortic dissection (1), @entity296 (2), @entity358 (5), and @entity357 (1). Inter-observer agreement ranged from 0.76 to 1 between senior radiologists and from 0.76 to 1 between resident and senior radiologists. The average time of image interpretation ranged from 14 to 15 minutes. CONCLUSION: ECG-gated whole chest CT angiography appears as a promising tool for the evaluation of acute @entity662 . Combined evaluation of appearance and function of the myocardium can reveal additional interesting information.
