To retrospectively evaluate the clinical value of dual-source computed tomography (DSCT) coronary angiography in the diagnosis of coronary artery anomalies.
A large cohort of 3625 consecutive patients, who underwent DSCT coronary angiography in our institute, was reviewed for coronary artery anomalies. All images were evaluated by two experienced readers using axial source images, multi-planar reformations (MPR), maximum intensity projections (MIP) and volume rendering (VR). Coronary artery anomalies were found in 36 patients (male 20, female 16, mean age 48 years, range 15-76 years). Of the 36 patients, 19 patients also underwent conventional coronary angiography (CCA).
The incidence of coronary artery anomalies was 0.99% (36/3625). Six different types of coronary artery anomalies were diagnosed by DSCT coronary angiography: (1) 11 anomalies of the right coronary artery; (2) five anomalies of the left coronary artery; (3) 10 anomalies of the left circumflex artery; (4) two single coronary artery; (5) one anomalous pulmonary origin of the coronary artery; (6) seven coronary artery fistula. Evaluation of the CCA resulted in a precise diagnosis in 53% (10/19) patients.
DSCT coronary angiography is a good diagnostic tool to examine coronary artery anomalies.
回顾性评价双源 CT（DSCT）冠状动脉成像在诊断冠状动脉异常中的临床价值。
对在我院行 DSCT 冠状动脉成像的 3625 例连续患者的大样本进行了冠状动脉异常的回顾性评估。两名有经验的读者使用轴位源图像、多平面重建（MPR）、最大密度投影（MIP）和容积再现（VR）对所有图像进行了评估。在 36 例患者（男 20 例，女 16 例，平均年龄 48 岁，范围 15-76 岁）中发现了冠状动脉异常。其中 19 例患者还接受了常规冠状动脉造影（CCA）。
冠状动脉异常的发生率为 0.99%（36/3625）。DSCT 冠状动脉成像诊断了 6 种不同类型的冠状动脉异常：（1）11 例右冠状动脉异常；（2）5 例左冠状动脉异常；（3）10 例左回旋支异常；（4）2 例单支冠状动脉异常；（5）1 例异常肺起源的冠状动脉；（6）7 例冠状动脉瘘。CCA 的评估在 53%（10/19）的患者中得到了准确的诊断。
DSCT 冠状动脉成像术是一种很好的检查冠状动脉异常的诊断工具。
