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.

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.

Diffusion Weighted Imaging in Spine Tumors
Neuroimaging Clinics of North America, 2023Diffusion weighted imaging (DWI) has developed into a powerful tool for the evaluation of spine tumors, particularly for the assessment of vertebral marrow lesions and intramedullary tumors. Advances in magnetic resonance techniques have improved the quality of spine DWI and diffusion tensor imaging (DTI) in recent years, with increased reproducibility

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 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

Diffusion-Weighted Imaging of Cerebral Malaria
Journal of Neuroimaging, 2005Cerebral malaria occurs in 2% of patients infected by Plasmodium falciparum. Magnetic resonance imaging findings of small white matter infarcts due to cerebral malaria have been previously reported, however nonspecific. Since diffusion-weighted imaging can differentiate acute embolic infarcts from other chronic or nonspecific white matter lesions, it ...

MRI plays a pivotal role in the management of patients with cancer, being used at every stage of the cancer patient’s journey. However, morphological assessments have substantial limitations. For example, detection of malignant lesions can often be difficult, particularly when disease burden is small and intermixed with normal tissues or benign disease

How to perform diffusion-weighted imaging
Child's Nervous System, 2001Diffusion-weighted imaging (DWI) has become an invaluable tool in the management of patients with stroke. DWI relies on detecting the random diffusion of water molecules. In normal tissues this movement may be restricted by the presence of cellular structures, which provide a barrier to free movement.

Diffusion-Weighted Imaging of the Male Pelvis
Radiologic Clinics of North America, 2012Diffusion-weighted magnetic resonance (MR) imaging (DWI) is now widely incorporated as a standard MR imaging sequence for the assessment of the male pelvis. DWI can improve the detection, characterization, and staging of pelvic malignancies, such as prostate, bladder, and rectal cancers.
