Predicting Clinical Improvement in Chronic Low Back Pain Using Exercise‐Induced IVIM Perfusion: Threshold Evaluation and Disability‐Dependent Effects

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
Previous findings showed that IVIM measures in lumbar muscles in response to acute exercise could predict response to exercise‐based rehabilitation in chronic low back pain. Here, we tested this in a larger independent cohort (n = 37), confirming greater increases in muscle diffusion (D) after exercise in those who responded to rehabilitation. However,

Histogram analysis of IVIM MRI for differentiating glioma IDH-1 status, grade, and Ki-67 expression: a comparison of bi-exponential models at multiple B-value

BMC Medical Imaging
Background Intravoxel Incoherent Motion (IVIM) offers valuable insights into tumor microstructural heterogeneity through diffusion and perfusion. However, the relationship between these features and glioma grading, IDH-1 status, and Ki-67 expression ...

Image denoising substantially improves accuracy and precision of intravoxel incoherent motion parameter estimates. [PDF]

PLoS ONE, 2017
Applicability of intravoxel incoherent motion (IVIM) imaging in the clinical setting is hampered by the limited reliability in particular of the perfusion-related parameter estimates.

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)

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.

Noninvasive assessment of endometrial fibrosis in patients with intravoxel incoherent motion MR imaging

Scientific Reports, 2021
Recently, few noninvasive methods have been reported to evaluate endometrial fibrosis. Our study was to investigate the feasibility of intravoxel incoherent motion (IVIM) MR imaging in the detection of endometrial fibrosis in patients with intrauterine ...

Simultaneous T2, T2*, and R2′ Mapping for Multiple Sclerosis Using Nonlinear Model‐Based Reconstruction of Undersampled Radial RARE‐EPI MRI

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1872-1892, October 2026.
ABSTRACT Purpose To demonstrate the synergy of undersampled radial 2in1‐RARE‐EPI acquisition and nonlinear model‐based reconstruction for accelerated and simultaneous T2, T2*, and R2′ mapping in brains of patients with multiple sclerosis (MS). Methods 2in1‐RARE‐EPI combines a RARE module with an EPI module to capture T2 and T2* information.

Role of intravoxel incoherent motion diffusion-weighted MRI in differentiation of renal cell carcinoma subtypes

The Egyptian Journal of Radiology and Nuclear Medicine
Background Renal cell carcinoma is the most fatal form of renal tumors, representing about ninety percent of all renal cancers. There are different variations in prognosis among various histological types of RCC. In recent years, there has been a greater

Technical Feasibility of IVIM for Prostate Cancer Imaging Using High‐Amplitude Whole‐Body Gradient System With Spiral Readout and Velocity‐Compensated Diffusion Encoding

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
The combination of velocity‐compensated diffusion encoding, spiral readout and strong gradients enabled high‐quality prostate IVIM imaging, offering a promising framework for the development of reliable IVIM‐based biomarkers for prostate cancer detection, characterisation and monitoring.
