ABSTRACT

Objective To evaluate the value of multi-slice spiral computed tomography angiography(MSCTA)scanning and reconstruction technology in detecting anomalous origin of coronary artery(AOCA).Methods Retrospective analysis was done in 3 856 patients who accepted MSCTA.Volume rendering(VR),multi-planar reformation(MPR),curved planar reformation(CPR)and maximum intensity projection(MIP)were used to observe the origin and course of coronary artery.Results 42 patients with AOCA were detected among 3 856 objects,and the detection rate was 1.09%.The detection rates had no statistically significant difference between male(1.17%)and female(0.98%).The rate of patients with anomalous origin of left coronary artery was 30.95%(13/42), and 9 objects(69.23%,9/13)of them had the anomalous origin of left circumflex.The rate of patients with anomalous origin of right coronary was 66.67%(28/42),and 35.71% of them(17/28)were found to have the anomalous origin of right coronary artery from the left sinus of valsalva.Conclusion MSCTA scanning and reconstruction technology is noninvasive,rapid,accurate and intuitive.
