Selective microvascular muscle perfusion imaging in the shoulder with intravoxel incoherent motion (IVIM)

, 2017
The evaluation of local muscle recruitment during a specific movement can be done indirectly by measuring changes in local blood flow. Intravoxel incoherent motion perfusion imaging exploits some properties of the magnetic resonance to measure locally ...

Intravoxel Incoherent Motion Imaging in Small Vessel Disease Microstructural Integrity and Microvascular Perfusion Related to Cognition

, 2017
Background and Purpose-Cerebral small vessel disease (SVD) is associated with cognitive impairment. This may be because of decreased microstructural integrity and microvascular perfusion, but data on these relationships are scarce.

Research progress on application of diffusion weighted imaging and introvoxel incoherent motion in the diagnosis of diabetic nephropathy

Linchuang shenzangbing zazhi, 2020
Diabetic nephropathy(DN)is one of main chronic microvascular complications of diabetes mellitus(DM).Previous early diagnosis of DN mainly relied on medical history,laboratory examination and renal biopsy,but laboratory examination was easily affected by ...

Regional disparities in cerebral perfusion and brain tissue microstructure damage in adult patients with Moyamoya syndrome

Scientific Reports
In Moyamoya syndrome (MMS), cerebral perfusion and tissue microstructure are impaired, but regional differences remain unclear. This study analyzed 22 adult MMS patients using CT perfusion (CTP) and intravoxel incoherent motion (IVIM).

IVIMFitSlicer: an open-source 3D Slicer extension for multi-model intravoxel incoherent motion (IVIM) diffusion-MRI analysis

SoftwareX
Intravoxel incoherent motion (IVIM) modelling separates tissue diffusion from microcapillary perfusion in diffusion-weighted MRI, but the estimated parameters depend strongly on the fitting model and algorithm, and most implementations are script-based ...

Intravoxel incoherent motion perfusion imaging in acute stroke: initial clinical experience

, 2014
Introduction: Intravoxel incoherent motion (IVIM) imaging is an MRI perfusion technique that uses a diffusion-weighted sequence with multiple b values and a bi-compartmental signal model to measure the so-called pseudo-diffusion of blood caused by its ...
