To assess whether 3D MRIPH and 3D TOF MRA at 3T could be used for arterial wall evaluation independent of 2D multi-contrast MRI sequences. 10 patients were scanned and acquired 3D High-Spatial-Resolution MRIPH, 3D TOF, and 2D multi-contrast MRI. Lumen boundary on 3D TOF and outer wall boundary on 3D MRIPH were segmented, as well as on the 2D multi-contrast images. There is very close agreement between 3D MRIPH combined with 3D TOF MRA when compared to the 2D multi-contrast MRI. This methods give a thorough description of atherosclerotic vessel wall disease. It potentially overcomes some problems of prolonged scan time and registration of images from multiparametric 2D data sets.
