Duplicated right coronary artery: multidetector CT angiographic findings.

Multidetector CT is becoming an alternative method for the diagnosis of coronary artery anomalies. We present the multidetector coronary CT angiography findings from a patient with right coronary artery duplication. Two separate right coronary arteries originating from the right aortic sinus were observed. Their anatomical course was well depicted, and atherosclerosis was excluded based on the CT angiography findings.
