Predicting Clinical Improvement in Chronic Low Back Pain Using Exercise-Induced IVIM Perfusion: Threshold Evaluation and Disability-Dependent Effects. [PDF]

NMR Biomed
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,

High-Resolution IVIM MRI Characterizes Diffusion-Perfusion Properties of the Parasagittal Dura. [PDF]

NMR Biomed
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 ...

Placental Blood-Flow Velocity Quantification From Diffusion MRI. [PDF]

Magn Reson Med
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.

Accurate estimation of intravoxel incoherent motion parameters based on implicit neural representation. [PDF]

Med Phys
Abstract BackgroundIntravoxel incoherent motion (IVIM) diffusion‐weighted imaging has important value in treatment response monitoring. However, traditional voxel‐wise independent fitting methods are highly sensitive to noise and do not utilize spatial correlation, resulting in unstable parameter estimation. Although existing deep learning methods have

Prognostic value of IVIM-DWI parameters for overall and recurrence-free survival in resected esophageal squamous cell carcinoma [PDF]

Cancer Imaging
Purpose Prognostic stratification after surgical resection remains challenging in esophageal squamous cell carcinoma (ESCC), as pathological staging cannot quantitatively capture intratumoral heterogeneity. Intravoxel incoherent motion diffusion-weighted
