Hybrid intravoxel incoherent motion–diffusion kurtosis imaging in brain MRI: A scoping review of applications, insights, and emerging directions

Journal of Magnetic Resonance Open
Intravoxel incoherent motion (IVIM) and diffusion kurtosis imaging (DKI) are advanced diffusion MRI techniques that respectively characterize microvascular perfusion and non-Gaussian diffusion.

Non-parametric intravoxel incoherent motion analysis in patients with intracranial lesions: Test-retest reliability and correlation with arterial spin labeling

NeuroImage: Clinical, 2016
Intravoxel incoherent motion (IVIM) analysis of diffusion imaging data provides biomarkers of true passive water diffusion and perfusion properties. A new IVIM algorithm with variable adjustment of the b-value threshold separating diffusion and perfusion

Bi-Stretched Exponential Model and Parameters Estimation Based on Dual Minimization Deep Neural Network

Journal of Harbin University of Science and Technology
Intravoxel incoherent motion ( IVIM) is the only medical imaging technique that does not require contrast agent. However, existing bi-exponential model cannot reflect the non-Gaussian features of diffusion and perfusion motions, and the fitting method of

Intravoxel incoherent motion perfusion in patients with Moyamoya disease: comparison with O-gas positron emission tomography

Acta Radiologica Open, 2019
Background Intravoxel incoherent motion magnetic resonance imaging (IVIM) enables non-invasive measurement of brain perfusion. Purpose To investigate whether IVIM could be used to evaluate the hemodynamic disturbance of Moyamoya disease (MMD) by ...
