Myocardial perfusion MRI with SW-CG-HYPR allows increased spatial coverage (whole left ventricular coverage), resolution, signal-to-noise ratio and reduced motion artifacts. The accuracy of this technique for detecting CAD has not been determined in a large number of patients. In this work, we have prospectively examined the diagnostic value of adenosine-induced stress myocardial perfusion MRI using SW-CG-HYPR in 50 patients with suspected CAD. Using the SW-CG-HYPR method, perfusion MRI was able to cover the whole left ventricle with an accuracy of 90% and 93% based on per-patient and per-vessel analyses, respectively, using X-ray coronary angiography as a reference standard.
