Conventional magnetic resonance imaging (MRI) is widely used for the diagnosis and monitoring of multiple sclerosis (MS), because it is more sensitive than clinical assessment in detecting disease dissemination over space and time [1] and for revealing the occurrence of disease activity and the accumulation of disease burden over time.

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 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 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

Technical Basics of Diffusion-Weighted Imaging
Magnetic Resonance Imaging Clinics of North America, 2021Diffusion-weighted images provide a unique contrast that shows the ability to assess tissue structure and condition on a micrometer scale. Notably, these equations are necessary to understand diffusion MR imaging as a theory but not for real imaging, particularly in clinical practice.

Water Molecules Diffusion in Diffusion Weighted Imaging
2014In the studying of fibers microstructure of brain white matter, many reconstruction methods have been proposed to interpret the diffusion-weighted signal. Those methods can be categorized into model-based and model-free methods. In this paper, the diffusion configuration of water molecules are discussed, and two questions are put forward to analyze the

Diffusion-weighted imaging of the spinal cord
Neuroimaging Clinics of North America, 2002Spinal cord DWI may be useful in providing information not available with conventional MR imaging. More work, however, is required to explain what the qualitative and quantitative results actually represent. Computer simulations and detailed radiologic-histologic correlations will therefore be necessary.

Diffusion-weighted Magnetic Resonance Imaging (dMRI) has long proven to be a versatile tool for the in vivo microstructural investigation of the human brain (Le Bihan 2003), the spinal cord (Clark et al. 1999), or even muscle tissue (Sinha et al. 2006). In contrast to conventional weighted MRI or functional MRI discussed in the preceding Chap. 4, it is

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 ...

A new method for diffusion weighted imaging
Magnetic Resonance Imaging, 1993A new method for generating diffusion contrast in magnetic resonance imaging is presented. This technique is robust enough to allow implementation on conventional imaging systems without hardware modifications. Results from phantom measurements are reported. Qualitative contrast changes in magnetic resonance images derived from live mammalian brain are
