A consistent, reliable, 3D myocardial first-pass perfusion sequence is developed using a stack-of-stars design and tested at both stress and rest during free-breathing. A compressed sensing algorithm is used to compensate for the high undersampling rates, including a modified form with temporal pixel reordering designed to better cope with respiratory motion. Reconstructions were successful, despite large respiratory motion, in all cases. An example of a perfusion defect in a coronary artery disease patient is presented, with confirmation from recent SPECT myocardial perfusion scintigraphy.
