Magnetic resonance imaging of coronary arteries, the ischemic cascade, and myocardial infarction

Sensitivity and specificity in detecting single vein grafts with 50% and 70% stenosis were 94%/63% and 96%/ 92%, respectively. [...]MRI flow velocity measurements may be useful for detecting flow-limiting lesions in bypass grafts and recipient vessels.
