Intravoxel incoherent motion MRI in neurological and cerebrovascular diseases

NeuroImage: Clinical, 2018
Intravoxel Incoherent Motion (IVIM) is a recently rediscovered noninvasive magnetic resonance imaging (MRI) method based on diffusion-weighted imaging. It enables the separation of the intravoxel signal into diffusion due to Brownian motion and perfusion-

Perfusion measurement in brain gliomas with intravoxel incoherent motion MRI [PDF]

American Journal of Neuroradiology, 2014
BACKGROUND AND PURPOSE: Intravoxel incoherent motion MRI has been proposed as an alternative method to measure brain perfusion. Our aim was to evaluate the utility of intravoxel incoherent motion perfusion parameters (the perfusion fraction, the ...

Dependence of brain intravoxel incoherent motion perfusion parameters on the cardiac cycle.

PLoS ONE, 2013
Measurement of microvascular perfusion with Intravoxel Incoherent Motion (IVIM) MRI is gaining interest. Yet, the physiological influences on the IVIM perfusion parameters ("pseudo-diffusion" coefficient D*, perfusion fraction f, and flow related ...

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).

Functional mapping of the human visual cortex with intravoxel incoherent motion MRI.

PLoS ONE, 2015
Functional imaging with intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) is demonstrated. Images were acquired at 3 Tesla using a standard Stejskal-Tanner diffusion-weighted echo-planar imaging sequence with multiple b-values. Cerebro-

Intravoxel incoherent motion imaging using spin echoes.

Magnetic Resonance in Medicine, 1991
International audienceThe purpose of this paper is to review the basic principles of diffusion measurement with spin echoes. These principles can be combined with those of MR imaging to generate maps of diffusion coefficients.
