Abstract:
Objective To observe the role of dual-source CT (DSCT) in the diagnosis of coronary artery fistula. Methods Nine patients with coronary artery fistula were examined with dual-source CT coronary artery angiography. Then the source images were post processed using volume rendering (VR), multiple planar reformation (MPR), maximum intensity projection (MIP) and curved planar reformation (CPR), and sequential segmental analysis of the intracardiac and extracardiac anomalies was performed. Results Coronary artery fistula in all the 9 patients were accurately displayed with DSCT, including 2 with left main trunk to right ventricle fistula, 7 with left main trunk and (or) left anterior descending artery to main pulmonary trunk fistula, 5 with complex coronary-pulmonary artery fistula. Conclusion Dual-source CT coronary artery angiography is convenient, fast, non-invasive, and may be the preferable method for diagnosis of coronary artery fistula.
