Background The effects of ischemia are first realized in the subendocardium and progress transmurally. Hence, detection of the transmural extent of myocardial perfusion (MP) defects has important diagnostic/prognostic implications. Systolic MP imaging using ECG-gated methods has been shown to provide improved visualization of subendocardial defects [1]. We developed an innovative non-ECGgated p...
Introduction: Coronary MR Angiography is a valuable tool for non-invasive assessment of coronary arteries. Presently, contrastenhanced, fat-saturated, ECG-triggered and navigator-gated 3D spoiled gradient-echo sequence is employed for whole-heart Coronary MRA at 3T. However, large static field variations at 3T frequently result in non-uniform fat-suppression over the field-of-view (FOV), obscur...
