MR Coronary angiography (MRCA) technology can observe the anatomical morphology of coronary arteries and detect lumen stenosis, dilation, and abnormal wall lesions [1]. MRCA technology is relatively complex with long scanning time [2]. Compressed SENSE (CS) technology can greatly shorten the scanning time and improve the rate of succussed examination. This study aim to explore the clinical feasibility of Compressed SENSE technology in non-contrast agent MRA and explore the best acceleration factor of CS.
