This study evaluated the ability of black blood coronary arterial wall MRI to identify the coronary artery plaque, using intravascular ultrasound (IVUS) as the golden standard. The vessel cross-sectional area (CSA), luminal CSA, maximal wall thickness, plaque burden of MRI cross-section coronary wall imaging in 19 patients were compared with IVUS. And It showed a good agreement between IVUS and MRI with regard to extent of wall thickening although MRI overestimated plaque burden and degree of luminal stenosis, which is the difference in spatial resolution between techniques.
