Effects of Echo Time on IVIM Quantification of the Normal Prostate [PDF]
Scientific Reports, 2018 The two-compartment intravoxel incoherent motion (IVIM) theory assumes that the transverse relaxation time is the same in both compartments. However, blood and tissue have different T2 values, and echo time (TE) may thus have an effect on the ...

Bifurcated topological optimization for IVIM [PDF]
Frontiers in Neuroscience, 2021 In this work, we shed light on the issue of estimating Intravoxel Incoherent Motion (IVIM) for diffusion and perfusion estimation by characterizing the objective function using simplicial homology tools.

On the Origins of the Cerebral IVIM Signal [PDF]
, 2017 PurposeIntravoxel incoherent motion (IVIM) has been proposed as a means of non-invasive MRI measurement of perfusion parameters such as blood flow and blood volume. Its main competitor in the brain is arterial spin labelling (ASL). In theory, IVIM should

Intravoxel Incoherent Motion (IVIM)
, 2020 Intravoxel incoherent motion (IVIM) can be seen as subfield of diffusion MRI. It allows tissue microcirculation (perfusion) to be investigated in addition to tissue microstructure (from molecular diffusion).

Longitudinal Correlations Between Intravoxel Incoherent Motion (IVIM) and Dynamic Contrast-Enhanced (DCE) MRI During Radiotherapy in Prostate Cancer Patients [PDF]
Frontiers in Oncology, 2022 PurposeIntravoxel incoherent motion (IVIM) is a promising technique that can acquire perfusion information without the use of contrast agent, contrary to the more established dynamic contrast-enhanced (DCE) technique.

Neural networks improve repeatability of intravoxel incoherent motion (IVIM) parameter estimation in pancreatic diffusion-weighted MRI. [PDF]
Med Biol Eng ComputIntravoxel incoherent motion (IVIM) analysis in diffusion-weighted MRI (DWI-MRI) shows potential for characterizing pancreatic tissue, but its clinical application remains limited by sensitivity to fitting algorithms.
