Simple and reliable determination of intravoxel incoherent motion parameters for the differential diagnosis of head and neck tumors. [PDF]

PLoS ONE, 2014
Intravoxel incoherent motion (IVIM) imaging can characterize diffusion and perfusion of normal and diseased tissues, and IVIM parameters are authentically determined by using cumbersome least-squares method.

Prandial Effects on Intravoxel Incoherent Motion Quantification in the Liver

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the feasibility of detecting prandial (i.e., meal) induced changes in microvascular flow in the liver, including changes in the spatial distribution of flow velocities, using intravoxel incoherent motion (IVIM) MRI. Methods Thirteen (n = 13) healthy volunteers underwent two liver MR exams: one preprandial after fasting and ...

IVIM dataset

, 2016
IVIM.nii.gz is an acquired IVIM dataset with 21 b-values acquired in 3 directions, registered to each other and the directions were averaged into one. So this dataset is 4D where the 4th dimension is the b-values.IVIM.bvecs are the b-vectors, which are ...

Enabling highly accelerated multi-shot IVIM-DWI with a Data-sharing-guided framework: Joint image reconstruction and biomarker estimation

NeuroImage
Purpose: To develop a novel deep learning-based data-sharing-guided framework for jointly generating high-quality intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) images and IVIM-biomarker maps from highly accelerated under-sampled ...

Repeatability of IVIM biomarkers from diffusion‐weighted MRI in head and neck: Bayesian probability versus neural network [PDF]

, 2021
Purpose: The intravoxel incoherent motion (IVIM) model for DWI might provide useful biomarkers for disease management in head and neck cancer. This study compared the repeatability of three IVIM fitting methods to the conventional nonlinear least-squares

Parametric response mapping of co-registered intravoxel incoherent motion magnetic resonance imaging and positron emission tomography in locally advanced cervical cancer undergoing concurrent chemoradiation therapy

Physics and Imaging in Radiation Oncology
Background and Purpose: Intravoxel-incoherent-motion (IVIM) magnetic-resonance-imaging (MRI) and positron-emission-tomography (PET) have been investigated independently but not voxel-wise to evaluate tumor microenvironment in cervical carcinoma patients.

Real‐Time Targeted Slice Reacquisition for Motion‐Corrupted Fetal Diffusion MRI

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2140-2151, November 2026.
ABSTRACT Purpose To develop and evaluate a real‐time framework for targeted slice‐level reacquisition in fetal diffusion MRI. Methods A DW‐SE‐EPI sequence was modified to support independent diffusion preparation per slice. A pathology‐robust nnU‐Net segmentation network, updated from a previously published baseline (V1) using pathological fetal cases ...
