Placental Blood‐Flow Velocity Quantification From Diffusion MRI

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2967-2977, December 2026.
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.

Combined ADC and T2 Mapping in the Prostate Using a 3D Reduced FOV Sequence

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2292-2308, November 2026.
ABSTRACT Purpose To develop a 3D reduced FOV sequence for combined ADC and T2 mapping in the prostate in a single scan. Methods A 3D ADC and T2 mapping reduced FOV acquisition is enabled using T2 and diffusion preparation modules with slab‐selective tip‐down pulses and magnitude stabilizer gradients.

Selective microvascular muscle perfusion imaging in the shoulder with intravoxel incoherent motion (IVIM)

, 2017
The evaluation of local muscle recruitment during a specific movement can be done indirectly by measuring changes in local blood flow. Intravoxel incoherent motion perfusion imaging exploits some properties of the magnetic resonance to measure locally ...

High‐Resolution IVIM MRI Characterizes Diffusion–Perfusion Properties of the Parasagittal Dura

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
Parasagittal dura demonstrates intermediate diffusion and elevated perfusion‐related IVIM metrics compared with brain parenchyma, reflecting its unique microfluidic environment at the CSF–dura interface. IVIM imaging of the parasagittal dura provides a rapid, noncontrast MRI approach to assess dural fluid transport and may offer a potential imaging ...

Brain protein burden is related to intravoxel incoherent motion: PET-MR imaging study

Frontiers in Neuroscience
IntroductionDysfunction in brain protein clearance mechanisms is thought to contribute to many neurodegenerative diseases, yet non-invasive assessment of these mechanisms in humans remains challenging.

Exploring the Mechanism of Postpartum Cognitive Dysfunction in a Preeclampsia Rat Model via Multimodal Imaging

The FASEB Journal, Volume 40, Issue 19, 15 October 2026.
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)

Progress of intravoxel incoherent motion diffusion-weighted imaging in liver diseases

World Journal of Clinical Cases, 2020
Traditional magnetic resonance (MR) diffusion-weighted imaging (DWI) uses a single exponential model to obtain the apparent diffusion coefficient to quantitatively reflect the diffusion motion of water molecules in living tissues, but it is affected by blood perfusion.

Diffusion MRI of the Body: Beyond PGSE‐EPI

Journal of Magnetic Resonance Imaging, Volume 64, Issue 4, Page 881-897, October 2026.
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.
