IVIM has been proposed as a method of imaging blood volume fraction and perfusion in the brain. In this study we directly compared both the images and the values measured with IVIM to a multi post label delay pCASL sequence in the same imaging session. Although the units are not directly comparable, the images can be visually compared, and it was hypothesised that inter-subject variability in resting CBF in grey matter across subjects would result in a positive correlation between measures from the 2 modalities. Although visually similar, no correlation was observed in the quantitative data.
