Diffusion-weighted imaging in neonates

Child's Nervous System, 2001
Diffusion-weighted imaging (DWI) can readily be performed in the neonate, although currently studies remain a few years behind-those carried out on adults. DWI relies on the random diffusion of water molecules. As for the adult population, a pulsed gradient spin echo sequence (PGSE) with cardiac gating can be used to exploit the effect of diffusion on ...

Diffusion-weighted imaging in Sydenham’s chorea

Child's Nervous System, 2012
The purpose of this study was to determine of caudate nucleus changes in diffusion-weighted magnetic resonance imaging.A total of 13 children (four males and nine females) with history of Sydenham's chorea and 13 healthy controls were included in to the study.

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

From diffusion‐weighted MRI to anomalous diffusion imaging

Magnetic Resonance in Medicine, 2008
AbstractWe present a novel interpretation of non‐monoexponential diffusion‐weighted signal decay with b‐value in terms of the theory of anomalous diffusion. Anomalous diffusion is the theory of diffusing particles in environments that are not locally homogeneous, such as brain tissue.

Diffusion‐weighted imaging in brain aspergillosis

European Journal of Neurology, 2007
Brain aspergillosis is a rare pathology, occurring mainly in immunocompromised patients, responsible for multiple cerebral septic infarctions. Some researchers have described magnetic resonance (MR) findings in cerebral invasive aspergillosis, but diffusion‐weighted imaging (DWI) has rarely been reported, especially in typical non‐enhancing lesions ...

Diffusion-weighted imaging in multiple sclerosis

The Italian Journal of Neurological Sciences, 1999
Diffusion-weighted imaging (DWI) provides a unique form of magnetic resonance (MR) contrast that enables the diffusional motion of water molecules to be quantitatively measured. As a consequence, DWI provides information about the orientation, size and geometry of brain structures.

Diffusion-Weighted Imaging Analysis

2013
In this chapter, we present methods to analyze three types of diffusion-weighted imaging (DWI), i.e., diffusion tensor imaging (DTI), Q-ball imaging (QBI), and diffusion spectrum imaging (DSI). DWI is one of the methods to measure water diffusion in tissues.

Diffusion-weighted imaging of the orbit

Clinical Radiology
Orbital lesions compose a heterogeneous group of pathologies that often present with non-specific imaging findings on conventional magnetic resonance imaging (MRI) sequences (T1-and T2-weighted). Accordingly, the application of diffusion MRI offers an opportunity to further distinguish between lesions along this spectrum.
