Perfusion/Diffusion Quantitation with Magnetic Resonance Imaging

Investigative Radiology, 1992
Quantitation of perfusion and diffusion in tissues using magnetic resonance imaging (MRI) techniques is an active area of research in many laboratories. Several different approaches have been taken to address the problem of determining microcirculatory flow or perfusion in the body with MRI.

Diffusion tensor magnetic resonance imaging in multiple sclerosis

Neurology, 2001
To quantify, using diffusion tensor imaging (DTI), the tissue damage in lesions and normal-appearing white matter (NAWM) from a large cohort of patients with MS and to investigate the magnitude of the correlation between DTI-derived metrics and clinical disability.Dual-echo and DTI scans were obtained from 78 patients with relapsing-remitting ...

Diffusion Magnetic Resonance Imaging in Infantile Neuroaxonal Dystrophy

Journal of Computer Assisted Tomography, 2003
A 7-month-old girl with infantile neuroaxonal dystrophy is reported. In diffusion MRI, the pyramidal tracts and dentate nuclei had high signal on b = 1,000 s/mm2 images and low apparent diffusion coefficient (ADC) values. This pattern likely reflected the presence of abnormal (dystrophic) axons with restricted mobility of water molecules.

Diffusion tensor magnetic resonance imaging

2018
The microstructure of the heart has a major impact on its mechanical and electrical properties. Diffusion tensor magnetic resonance imaging (DTI) exploits the anisotropic restriction of water diffusion in the myocardium to resolve its microstructure.

Nonketotic Hyperglycinemia: Diffusion Magnetic Resonance Imaging Findings

Journal of Computer Assisted Tomography, 2003
We report about a boy with nonketotic hyperglycinemia who was studied at 15 days of life with a follow-up examination at age 6 months. Magnetic resonance (MR) imaging revealed progressive atrophy, callosal thinning, and delayed myelination. Glycine peaks were shown by proton MR spectroscopy at 3.56 ppm with a long echo time (TE, 135 milliseconds; TR ...

Diffusion Magnetic Resonance Imaging in Neuroimaging

2008
Diffusion is one of the basic phenomena in nature and can be quantified with magnetic resonance imaging (MRI) in terms of signal attenuation. Diffusion MRI portrays the geometry of microstructures based on the fact that molecular diffusion varies in different directions and that the geometry can be faithfully reflected by the probability density ...

[Diffusion, perfusion and functional magnetic resonance imaging].

Journal des maladies vasculaires, 1995
Recent developments in the use of Magnetic Resonance Imaging (MRI) to measure and image molecular diffusion and blood microcirculation (perfusion) hold significant promise in the noninvasive evaluation of normal brain function and functional disorders. Molecular diffusion is the result of spontaneous random motion that involves all molecules and probes
