In the study, we sought to determine whether coronary vessel wall imaging using inversion recovery prepared SSFP correlate with atherosclerosis detected by 64 raw MDCT. IR-SSFP can be used to non-invasively visualize the coronary vessel wall and to detect the presence of (sub)clinical coronary atherosclerosis . HSI of IR-SSFP may be indicative of plaque inflammation and/or hemorrhage. Therefore, coronary plaque vulnerability could be predicted by cardiac MRI. Further studies are needed to define the importance of these findings in the detection and treatment of vulnerable plaques.
