Assessment of Intravoxel Incoherent Motion Diffusion‐Weighted Imaging in Insomnia
Brain and BehaviorPurpose Few studies have investigated insomnia using intravoxel incoherent motion imaging. The aim ofthis study was to evaluate the classification performance of intravoxel incoherent motion diffusion‐weighted imaging in differentiating between insomnia ...

Evaluation of Whole Brain Intravoxel Incoherent Motion (IVIM) Imaging
DiagnosticsIntravoxel Incoherent Motion (IVIM) imaging provides non-invasive perfusion measurements, eliminating the need for contrast agents. This work explores the feasibility of IVIM imaging in whole brain perfusion studies, where an isotropic 1 mm voxel is ...

A Simplified Model for Intravoxel Incoherent Motion Perfusion Imaging of the Brain [PDF]
American Journal of Neuroradiology, 2016 Despite a recent resurgence, intravoxel incoherent motion MRI faces practical challenges, including limited SNR and demanding acquisition and postprocessing requirements. A simplified approach using linear fitting of a subset of higher b-values has seen success in other organ systems.

Whole-body intravoxel incoherent motion imaging [PDF]
European Radiology, 2015 OBJECTIVES To investigate the technical feasibility of whole-body intravoxel incoherent motion (IVIM) imaging. MATERIALS AND METHODS Whole-body MR images of eight healthy volunteers were acquired at 3T using a spin-echo echo-planar imaging sequence with eight b-values. Coronal parametrical whole-body maps of diffusion (D), pseudodiffusion (D*), and the

On the Reproducibility of Inversion Recovery Intravoxel Incoherent Motion Imaging in Cerebrovascular Disease. [PDF]
AJNR Am J Neuroradiol, 2018 Intravoxel incoherent motion imaging can measure both microvascular and parenchymal abnormalities simultaneously. The contamination of CSF signal can be suppressed using inversion recovery preparation. The clinical feasibility of inversion recovery-intravoxel incoherent motion imaging was investigated in patients with cerebrovascular disease by ...

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-

Echo-planar imaging of intravoxel incoherent motion.
Radiology, 1990 The recently established single-shot technique of echo-planar imaging of intravoxel incoherent motion (IVIM) for determining and imaging the variations of microscopic motions of water has been applied to studies of water perfusion in phantoms and to in vivo studies of diffusion and perfusion in cat and human brains. The phantom results demonstrate that

Intravoxel incoherent motion imaging using spin echoes
Magnetic Resonance in Medicine, 1991 AbstractThe 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. Diffusion imaging can be extended to imaging of other intravoxel incoherent motions (IVIM), such as blood microcirculation.

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-

Incoherent-motion magnetic resonance imaging and pediatric Crohn disease
Archives of Clinical and Experimental Surgery, 2016 Crohn disease is a chronic inflammatory bowel disease of unknown etiology with approximately one-third of patients being children and adolescents. Long-standing inflammation can result in fibrostenosing disease, usually of the terminal ileum.
