Objective:
To determine the clinical value of 64-slice computed tomography angiography (CTA) in the diagnosis of coronary artery anomalies.
Methods:
The coronary artery imaging data of 852 patients who underwent 64-slice CTA from July 2006 to May 2007 were retrieved. The imaging features of coronary artery anomalies confirmed by selective coronary angiography were reviewed.
Results:
Eight (0.9%) coronary artery anomalies were found in the patients, which included 3 cases of anomalous aortic origin of coronary arteries, 3 cases of anomalous origin of the left main coronary artery from pulmonary artery, 1 case of coronary fistula from the right coronary artery to right atrium, and 1 case of coronary aneurysm.
Conclusion:
The 64-slice CTA can detect coronary anomalies and delineate the anatomic relationships among the peripheral structures, which can be considered as an early screening for coronary anomalies.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
