Placental Blood‐Flow Velocity Quantification From Diffusion MRI
ABSTRACT Purpose Altered placental capillary blood flow is closely linked to obstetric complications, yet quantifying capillary‐scale blood velocity remains challenging with existing imaging methods. This is partially because capillary networks form disordered microvascular beds at the voxel scale, rather than coherent, directional vessels.

Intravoxel incoherent motion (IVIM) modelling separates tissue diffusion from microcapillary perfusion in diffusion-weighted MRI, but the estimated parameters depend strongly on the fitting model and algorithm, and most implementations are script-based ...

Effect of intravoxel incoherent motion on diffusion parameters in normal brain
At very low diffusion weighting the diffusion MRI signal is affected by intravoxel incoherent motion (IVIM) caused by dephasing of magnetization due to incoherent blood flow in capillaries or other sources of microcirculation.

This schematic illustrates an L‐NAME‐induced preeclampsia (PE) rat model generated via L‐NAME administration to pregnant dams, wherein Morris water maze assessments confirmed progressive postpartum cognitive dysfunction that emerged at 10 days post‐partum and deteriorated further at 1 and 3 months post‐partum. Multimodal magnetic resonance imaging (MRI)

Diffusion MRI of the Body: Beyond PGSE‐EPI
ABSTRACT Diffusion magnetic resonance imaging (dMRI) is a widely used clinical imaging technique which is sensitive to changes in tissue microstructure including cellularity, perfusion, and tissue damage. DMRI has been used in whole‐body imaging as well as in targeted imaging of every major anatomical region.
