摘　　要：目的　探讨电子束CT(EBCT)在先天性冠状动脉异常诊断中的临床价值。方法　对EBCT诊断为先天性冠状动脉异常 ,并有心血管造影和 (或 )手术结果的 2 0例患者进行回顾性分析。其中 16例行心血管造影。男 13例 ,女 7例 ,年龄 5个月至 70岁 ,平均 15 5岁。除 1例行连续容积扫描外 ,19例采用单层增强扫描 ,其中 1例同时行单层平扫和电影序列 ,1例加行电影序列。结果　 2 0例中 ,EBCT提示 19例先天性冠状动脉异常征象并做出正确诊断 ,包括 5例起源分布异常、6例单支冠状动脉畸形和 8例冠状动脉瘘 ;造影 16例确诊 15例。两种诊断方法诊断结果无显著性差异 (经 χ2 检验 ,χ2 =0 32 ,P >0 0 5 )。Objective To evaluate the role of electron beam CT (EBCT)in the diagnosis of patients with congenital coronary artery anomalies. Methods Twenty patients with angiocardiography and (or) operation outcomes, and diagnosed as congenital coronary artery anomalies by means of EBCT were analyzed retrospectively. 16 patients had angiocardiographic results. The 13 male and 7 female patients ranged in age from 5 months to 70 years (median age was 15 5 years). Continuous volume scan (CVS) was performed on 1 patient, enhanced single slice mode (SSM) were done on 19 patients (95%) including one adding both plain SSM and cine study, and the other adding cine study. Results EBCT suggested signs of congenital coronary artery anomalies and made correct diagnosis in 19 patients, including 5 patients with anomalous origin and course, 6 patients with single coronary artery and 8 patients with coronary artery fistula. The correct diagnostic rate of EBCT was 19/20, while that of angiocardiography was 15/16. In the Chi square test, χ 2=0 32, P >0 05, so that there wasn′t significant difference between them. Conclusion Because of its remarkable advantage in demonstrating origin, course, and drainage sites of coronary artery anomalies, EBCT is an excellent noninvasive method in the diagnosis of coronary artery anomalies.
