Extended Data Fig. 4: mvPI maps and the high mvPI probability density distribution map of all other participants.
From: Assessing cerebral microvascular volumetric with high-resolution 4D cerebral blood volume MRI at 7 T
a, mvPI maps of all other young participants (besides S06, S07 and S08 shown in Fig. 3a), including 3 ones with retest session (green frame). Furthermore, these three subjects demonstrated relatively high repeatability in their results, despite the long intervals between scans (5–8 months). b, mvPI maps of all elder participants. As we can see, compared to young, the mvPI maps of older participants show the higher variability across participants. c, High mvPI probability density distribution map in white matter. The regions with high mvPI frequently seems localize to watershed areas between different vascular territories in the white matter.
