Diffusion Tensor Magnetic Resonance Imaging of Brain Tumors

Magnetic Resonance Imaging Clinics of North America, 2005
DTI seems to offer the possibility of adding important information to presurgical planning. Although experience is limited, DTI seems to provide useful local information about the structures near the tumor, and this seems to be useful in planning. In the future, DTI may provide an improved way to monitor intraoperative surgical procedures as well as ...

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 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.

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 of Solid Vestibular Schwannomas

Journal of Computer Assisted Tomography, 2003
Six patients with solid vestibular schwannomas were studied by diffusion magnetic resonance imaging to assess if this modality adds new information for these tumors, because there is no previous report in the relevant literature. The sizes of the tumors ranged from 2.2 to 4.7 cm with respect to their largest diameters.

Canavan Disease: Diffusion Magnetic Resonance Imaging Findings

Journal of Computer Assisted Tomography, 2003
A 15-month-old boy with Canavan disease is reported in whom a restricted diffusion pattern on diffusion magnetic resonance imaging (MRI) (high signal on b = 1,000 mm2/s images and low apparent diffusion coefficient [ADC] values) was evident in the affected regions of the brain, including the peripheral white matter, globi pallidi, thalami, brainstem ...

[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
