Intravoxel incoherent motion (IVIM) #MRI can sense both diffusion & microcirculation. We talked to Eric Sigmund—an authority on IVIM & a lead author of #IVIM guidelines—about why this dual capability matters, how standards can aid translation, & where cotton candy fits in: cai2r.net/eric-sigmund...

New for diffusion MRI researchers: the RICE toolbox for computing rotational invariants of the cumulant expansion (RICE). In recent work we demonstrate 21 such invariants, 14 of which are yet to be explored. Also sharing example data: cai2r.net/resources/ro... + @elsfi.bsky.social #diffusion #MRI 🧪
