This
study was to evaluate the ability of black-blood coronary wall MRI to identify
and classify coronary plaques by comparing with 64-MDCT.15 patients underwent
black-blood coronary wall MRI and coronary 64-MDCT. In MRI, the plaque
burden, maximal wall thickness, SNR, CNR in the coronary walls containing
plaques were greater than those of the normal coronary walls.The SNR in the
soft plaque was greater than those in calcified and mixed plaques. The
conclusion was coronary wall MRI can identify coronary plaques, and has the
potential to differentiate plaque types based on signal intensity.
