Evaluation of anomalous coronary artery anatomy using multi-detector CT.

Objective: Anomalous coronary vessels can result in sudden cardiac death. Coronary angiography is typically used to make the diagnosis; however, other modalities have been used, including transesophageal Doppler ultrasound, MRI, electron beam CT, and helical CT. We report two cases of evaluation of anomalous coronary vessels using multi-detector CT without cardiac gating.

Conclusion: Our experience suggests that multi-detector CT with its rapid scanning time, superior spatial resolution, and wide availability could make it a viable tool in the evaluation of anomalous coronary anatomy in angiographically equivocal cases.
