Validation of Intravoxel Incoherent Motion (IVIM) Methods in the Liver using the NIST Diffusion Phantom

ISMRM Annual Meeting
Intravoxel incoherent motion (IVIM) MRI is used to measure quantitative biomarkers of liver fibrosis, but accuracy and reproducibility of various methods requires validation. Six IVIM methods with different acquisition parameters (motion control techniques, b-values, single shot EPI v. SMS) were assessed using the NIST diffusion phantom.

Test-retest repeatability of intravoxel incoherent motion (IVIM) MRI in the cervical cord at 3T

ISMRM Annual Meeting
Motivation: High precision of intravoxel incoherent motion (IVIM) MRI parameters in the cervical cord can facilitate studies targeting perfusion impairment and substantiate clinical findings. Goal(s): To determine the test-retest repeatability of IVIM in the cervical cord using four different common model fitting approaches.

[Intravoxel incoherent motion (IVIM) imaging using an experimental MR unit with small bore].

Nihon Igaku Hoshasen Gakkai zasshi. Nippon acta radiologica, 1989
IVIM images were constructed from a pair of spin echo (SE) sequences on a 2T MR unit with small bore. In the current study, two types of SE were used: the standard SE and the other sensitized to microscopic incoherent motion by adding motion probing gradient on either side of 180 degrees pulse.
