Traditional coronary magnetic resonance angiography (MRA) is performed during the quiescent mid-diastolic period of the cardiac cycle. There is another quiescent period at end systole that has been not exploited for coronary MRA imaging. This study demonstrates the feasibility of imaging during this systolic period without a detrimental effect on image quality. This is made possible by using parallel imaging in the form of sensitivity encoding (SENSE) at 3T to abbreviate the systolic image data acquisition window.
