目的：目的：探讨延迟增强多层螺旋CT（MSCT）对冠状动脉造影（冠脉造影）正常的心肌炎和心肌梗死的鉴别诊断价值。方法：选择12例因急性胸痛而冠脉造影正常的患者。患者入院后36小时内和4天内分别进行延迟增强MSCT和钆后延迟增强磁共振成像（MRI）检查。延迟增强MSCT和MRI之间的比较进行了3个独立的盲观察员在最终诊断，涉及的节段数，和transmarticleextends.Results：心肌炎和心肌梗死之间的最终诊断是相同的延迟增强MSCT和MRI的参与节段数和transmarticleextension的显着协议。观察者间的再现性是好的两种techniques.Conclusions：我们证明，延迟增强MSCT可以区分心肌梗死和心肌炎，在急性期与MRI相比，具有相同的准确性。
Objective: To evaluate the accuracy of delayed-enhanced multi-detector computed tomography (MSCT) for differentiating between myocarditis and myocardial infarction in patients with normal x-ray coronary angiography.Methods: Twelve consecutive patients referred for acute chest pain and normal coronary arteries on x-ray coronary angiography were involved in this study. Delayed-enhanced MSCT and postgadolinium delayed-enhanced magnetic resonance imaging (MRI) examinations were performed within 36 hours and 4 days, respectively, after patient admission. Comparison between delayed-enhanced MSCT and MRI was performed by 3 independent blinded observers in term of final diagnosis, number of involved segments, and transmural extent.Results: Final diagnosis between myocarditis and myocardial infarction was identical for delayed-enhanced MSCT and MRI with a significant agreement for number of involved segments and transmural extension. Interobserver reproducibility was good for both techniques.Conclusions: We demonstrated that delayed-enhanced MSCT allows differentiation between myocardial infarction and myocarditis with the same accuracy at acute phase compared with MRI.
