Diffusion-weighted imaging in prostate cancer
Magnetic Resonance Materials in Physics, Biology and Medicine, 2021Diffusion-weighted imaging (DWI), a key component in multiparametric MRI (mpMRI), is useful for tumor detection and localization in clinically significant prostate cancer (csPCa). The Prostate Imaging Reporting and Data System versions 2 and 2.1 (PI-RADS v2 and PI-RADS v2.1) emphasize the role of DWI in determining PIRADS Assessment Category in each of

Diffusion-weighted imaging in Crohn’s disease
Die Radiologie, 2023Diffusion-weighted MRI (DWI) is routinely used in abdominal imaging. In addition to neoplastic diseases, inflammatory changes can be delineated and diagnosed based on diffusion restriction in DWI. DWI is also increasingly used in the context of MRI of the small and large intestine.This article focuses on the technical aspects of DWI and its role in the

Diffusion-weighted imaging in Sydenham’s chorea
Child's Nervous System, 2012The 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
1997Contrast 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‐weighted imaging in brain aspergillosis
European Journal of Neurology, 2007Brain 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, 1999Diffusion-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.

Sparse registration of diffusion weighted images
Computer Methods and Programs in Biomedicine, 2017Registration is a critical step in group analysis of diffusion weighted images (DWI). Image registration is also necessary for construction of white matter atlases that can be used to identify white matter changes. A challenge in the registration of DWI is that the orientation of the fiber bundles should be considered in the process, making their ...

Diffusion-weighted imaging of the orbit
Clinical RadiologyOrbital 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.

Diffusion-Weighted Imaging Analysis
2013In 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.
