title: Value of fast gradient echo magnetic resonance angiography as an adjunct to coronary arteriography in detecting and confirming the course of clinically significant coronary artery anomalies.
abstract: We investigated the additional value of magnetic resonance (MR) angiography in 12 patients with clinically significant coronary anomalies. In 5 patients, the referring cardiologist requested additional evaluation because coronary arteriography was inconclusive about the course of the anomaly. For comparison, 7 patients with known anomalous coronary arteries were collected from our database. In these patients, there had been no doubt about the course of the anomalous coronary arteries. MR angiography provided the diagnosis in all 5 patients in whom the diagnosis was inconclusive beforehand. From the 7 patients in whom diagnosis had been established previously by contrast arteriography, the anomaly was confirmed in 5 by MR angiography. In 1 patient, the initial diagnosis at contrast arteriography had to be changed as a result of MR angiography. In 1 patient, the MR image was of insufficient quality to be conclusive. In conclusion, in patients with angiographically suspected coronary anomalies, fast gradient echo MR angiography is a helpful adjunct to coronary arteriography in identifying and confirming the origin and course of clinically significant coronary anomalies. The additional value of fast gradient echo MR coronary angiography is the visualization of both the artery and its surrounding structures.
