Non-invasive demonstration of coronary artery anomaly performed using 16-slice multidetector spiral computed tomography.

Coronary artery anomalies are some of the most confusing, neglected topics in cardiology. Presently, no techniques are able to routinely screen those morphological alterations which can create potentially life-threatening complications, especially in young healthy subjects. Many efforts have been made to non-invasively image the coronary arteries using magnetic resonance, electron beam computed tomography, and recently multidetector computed tomography (MDCT). Even though interesting results have been reported, these techniques have hardly become an adequate substitute for conventional catheter coronary angiography. A new generation of MDCT scanners with 16 arrays of detectors and a higher temporal and spatial resolution have recently been introduced. We report a case of an anomalous coronary artery origin documented using a 16-slice MDCT scanner.
