DWI of the Breast – Possibilities and Limitations
RoFo Fortschritte Auf Dem Gebiet Der Rontgenstrahlen Und Der Bildgebenden Verfahren, 2022Background The MRI of the breast is of great importance in the diagnosis of disorders of the breast. This can be stated for the primary diagnosis as well as the follow up. Of special interest is diffusion weighted imaging (DWI), which has an increasingly important role.

AbstractDiffusion‐weighted MR imaging (DWI) is capable of imaging ischemia‐induced changes in water protons in either animal or man. Technical developments are described that allow the routine clinical utility of DWI in a stroke setting to provide objective criteria beyond the neurological exam by which the pathophysiology of stroke can be evaluated ...

ISMRM Annual Meeting, 2023
Diffusion MRI provides unique information on the structure, organization, and integrity of the nasopharyngeal carcinoma (NPC) non-invasively. Higher b-values diffusion-weighted imaging could improve the detection rate of malignancies. We use the combination of DWI TSE Multivane XD and computed DWI to generate the high b values diffusion for ...

DWI of the brain: Postmortal DWI of the brain in comparison with in vivo data
Forensic Science International, 2012Changes in water diffusion can be quantified by diffusion-weighted MR imaging. However, there are only few reports about changes in post mortem brain. The aim of this study was to investigate the temporal pattern of the apparent diffusion coefficient (ADC) in the brain after death, to compare the values to in vivo brain and to assess the value of ex ...

Dynamic contrast-enhanced MRI (DCE-MRI) of the breast has high sensitivity for breast cancer detection but lacks specificity for characterizing breast tumors. Hence, several studies have investigated the role of advanced MRI techniques, such as diffusion-weighted imaging (DWI), to improve the specificity of MRI for the evaluation of breast lesions and ...

Introduction: Our aim was to determine the prevalence and factors associated with delayed appearance of DWI lesion among initially DWI-negative clinically suspected stroke patients in the follow-up DWIs during in-hospital care. Method: Among 5271 patients admitted to stroke unit as ...

Future applications of DWI in MS
Journal of the Neurological Sciences, 2001Diffusion imaging is a noninvasive technique for measuring the movement of water molecules. Although it has had its greatest impact thus far in the area of stroke imaging, the information garnered from diffusion experiments can provide an indication of myelin injury and perhaps axonal integrity.

Neurologic care is increasingly being defined by rigorous assessment of therapeutic interventions. However, the therapeutic paradigm creates challenges when applied to diagnostic tests. Diagnostic information is only one of the many factors influencing decisions about the course of medical care.

DWI has expanded its applications outside the brain in the last years because of technological improvements in gradient strengths and sequences. Nowadays, DWI forms part of “state-of-the-art” liver MRI protocols, although lack of standardization limits its widespread use.
