Synopsis
IVIM signal intensities could be compared with the ‘ground truth’ by use of a micro-vessel phantom in this study. In IVIM imaging, images with b = 0 are often included in the analysis, but this study indicated that images with b = 0 should be excluded. In this study, IVIM analysis showed a tendency to overestimate D* and underestimate f.
