Pelvic Applications of Diffusion Magnetic Resonance Images

Magnetic Resonance Imaging Clinics of North America, 2011
Diffusion-weighted imaging (DWI) is a powerful imaging technique in neuroimaging; its value in abdominal and pelvic imaging has only recently been appreciated as a result of improvements in magnetic resonance imaging technology. There is growing interest in the use of DWI for evaluating pathology in the pelvis. Its ability to noninvasively characterize

Diffusion-Weighted Magnetic Resonance Imaging

1997
Contrast in magnetic resonance imaging (MRI) is generated by exploiting a variety of physicochemical properties. Conventional clinical MRI techniques are largely based upon disease-induced changes in water relaxation, but these have been complemented by a number of other approaches, including a sensitization to the diffusion of water. It has been shown

[Diffusion magnetic resonance imaging of thorax].

Tuberkuloz ve toraks, 2014
Although magnetic resonance imaging (MRI) of Thorax is only useful for morphological evaluation, currently we can use it for functional evaluation such as diffusion weighted imaging. Currently, we can obtain higher quality images because of new technologies such as software that decrease motion artefact, use of multi-channel, parallel imaging and fast ...

Diffusion tensor magnetic resonance image regularization

Medical Image Analysis, 2004
As multi-dimensional complex data become more common, new regularization schemes tailored to those data are needed. In this paper we present a scheme for regularising diffusion tensor magnetic resonance (DT-MR) data, and more generally multi-dimensional data defined by a direction map and one or several magnitude maps.

Phenylketonuria: Diffusion Magnetic Resonance Imaging and Proton Magnetic Resonance Spectroscopy

Journal of Computer Assisted Tomography, 2003
Two patients with phenylketonuria are reported with white matter lesions. Diffusion magnetic resonance (MR) imaging revealed restricted diffusion patterns (high signal) on b = 1000 s/mm2 images associated with low apparent diffusion coefficient values ranging between 0.44 x 10-3 mm2/s and 0.56 x 10-3 mm2/s.

Diffusion weighted magnetic resonance imaging in stroke

European Journal of Radiology, 2003
Diffusion weighted magnetic resonance imaging has evolved from an esoteric laboratory experiment to a critical aspect of routine clinical care of the patient presenting with symptoms suspicious of acute ischemic stroke. The purpose of this article is to review the basis of diffusion weighted imaging (DWI), to consider its application in acute stroke ...

Magnetization Transfer and Diffusion Tensor Magnetic Resonance Imaging

2002
Patients with primary progressive (PP) multiple sclerosis (MS) represent a subgroup with clinical and magnetic resonance (MR) imaging (MRI) characteristics which differ from those of patients with relapsing-remitting (RR) MS or secondary progressive (SP) MS [1,2]. Although they experience a progressive disease course from onset, the burden and activity

Diffusion Magnetic Resonance Imaging in Multiple Sclerosis

Neuroimaging Clinics of North America, 2011
Multiple sclerosis (MS) is considered the most common inflammatory autoimmune neurologic disorder and the most frequent cause of nontraumatic neurologic disability in young and middle-age adults. This article reviews the basic features of its magnetic resonance (MR) imaging lesions and, primarily, the use of diffusion MR imaging, which is increasingly ...

Magnetic resonance imaging studies of diffusion in polymers

Food Additives and Contaminants, 1997
For a number of polymer/penetrant systems, for example fatty foods in direct contact with plastic wrapping, the migration of substances from the polymer is governed by the amount of penetrant entering the polymer. For food packaging this means that the rate of migration of substances into the food can be governed by the uptake of food into the ...

Magnetic resonance imaging and diffusion‐weighted imaging in methylmalonic acidemia

Acta Radiologica, 2005
Methylmalonic acidemia (MMA) is an inborn disorder of amino acid metabolism, often presenting with neurological symptoms. We present the results of magnetic resonance imaging (MRI) and diffusion‐weighted imaging (DWI) of the brain in a 16‐month‐old male patient with classic neurological and laboratory findings for MMA.
