| Objective To retrospectively evaluate the clinical value of dual-source CT (DSCT) coronary angiography in the diagnosis of coronary artery anomalies. Methods A large cohort of 3625 consecutive patients, who underwent DSCT coronary angiography in our institute, were reviewed for coronary artery anomalies. All images were evaluated by two experienced readers using axial source images, multi-planar reformation (MPR), maximum intensity projection (MIP) and volume rendering (VR). Coronary artery anomalies were found in 36 patients (male 20, female 16, mean age 48 years, ranged 15—76 years). Of the 36 patients, 19 patients also underwent conventional coronary angiography (CCA). Results The incidence of coronary artery anomalies was 0.99% (36/3625). Six different types of coronary artery anomalies were diagnosed by DSCT coronary angiography: 11 anomalies of the right coronary artery, 5 anomalies of the left coronary artery, 10 anomalies of the left circumflex artery, 2 single coronary artery, 1 anomalous pulmonary origin of the coronary artery, 7 coronary artery fistula. Evaluation of the CCA resulted in a precise diagnosis in 52.63% (10/19) patients. Conclusion DSCT coronary angiography is a good diagnostic tool to examine variable coronary artery anomalies. |
