M4Raw Brain v1.6
M4Raw Brain is a multi-contrast, multi-repetition, four-channel k-space
dataset acquired on a 0.3-T whole-body MRI system. The release contains T1w,
T2w, FLAIR, and GRE brain acquisitions from healthy volunteers, including
explicit motion subsets and an expanded repeated-acquisition test cohort.
Companion dataset: M4Raw-Abdomen

Dataset Details
Dataset Description
As a membrane separating circulating blood and brain extracellular
fluid, the blood-brain barrier (BBB) is the protection layer that blocks most
foreign drugs. Thus the ability of a drug to penetrate the barrier to deliver
to the site of action forms a crucial challenge in development of drugs for the
central nervous system.
