MRI coronary angiography

MRCA Imaging A form of MR angiography used to ID clinically important coronary artery stenoses; with standard MRI spin-echo and gradient-echo techniques, coronary arterial visualization is suboptimal and limited to the proximal segments, apparently related to respiratory and cardiac movements; in MRCA, the image is obtained while holding the breath, reducing the respiratory 'noise'; cardiac movement is minimized by obtaining the image during mid-diastole–a point of the cardiac cycle with relative diastasis; the temporal resolution is minimized by using
k-space segmentation
