Diffusion weighted magnetic resonance imaging in stroke

European Journal of Radiology, 2003
Diffusion weighted magnetic resonance imaging has evolved from an esoteric laboratory experiment to a critical aspect of routine clinical care of the patient presenting with symptoms suspicious of acute ischemic stroke. The purpose of this article is to review the basis of diffusion weighted imaging (DWI), to consider its application in acute stroke ...

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

Magnetic resonance imaging and diffusion‐weighted imaging in methylmalonic acidemia

Acta Radiologica, 2005
Methylmalonic acidemia (MMA) is an inborn disorder of amino acid metabolism, often presenting with neurological symptoms. We present the results of magnetic resonance imaging (MRI) and diffusion‐weighted imaging (DWI) of the brain in a 16‐month‐old male patient with classic neurological and laboratory findings for MMA.

Diffusion-weighted Magnetic Resonance Imaging in Pituitary Abscess

Journal of Computer Assisted Tomography, 2006
Pituitary abscess is a rare but potentially life-threatening disease. The correct preoperative diagnosis of pituitary abscess is difficult and rarely made. We present a case of pituitary abscess where diffusion-weighted magnetic resonance imaging was useful in making the preoperative diagnosis of pituitary abscess.

Diffusion-Weighted Magnetic Resonance Imaging in Alzheimer’s Disease

Dementia and Geriatric Cognitive Disorders, 1999
Diffusion-weighted imaging (DWI) is a powerful new magnetic resonance imaging technique for evaluating tissue pathophysiology in vivo. We performed DWI in three orthogonal spatial directions in 10 patients with mild to moderate Alzheimer’s disease (AD) and 11 control subjects.

Diffusion-weighted magnetic resonance imaging in colorectal cancer

Journal of Visceral Surgery, 2016
Magnetic resonance imaging (MRI) plays now a major role in patients with colorectal cancer regarding tumor staging, surgical planning, therapeutic decision, assessment of tumor response to chemoradiotherapy and surveillance of rectal cancer, and detection and characterization of liver or peritoneal metastasis of colorectal cancers.

Diffusion-weighted magnetic resonance imaging in autoimmune pancreatitis

Japanese Journal of Radiology, 2009
The aim of this study was to investigate the usefulness of diffusion-weighted magnetic resonance imaging (DWI MRI) for the diagnosis and evaluation of autoimmune pancreatitis (AIP).A total of 4 consecutive patients with AIP, 5 patients with chronic alcoholic pancreatitis (CP), and 13 patients without pancreatic disease (controls) were studied.

Whole-body diffusion-weighted magnetic resonance imaging

European Journal of Radiology, 2009
Diffusion-weighted magnetic resonance imaging (DWI) provides information on the diffusivity of water molecules in the human body. Technological advances and the development of the concept of diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) have opened the path for routine clinical whole-body DWI.

Diffusion-weighted magnetic resonance imaging of pancreas tumours

European Radiology, 2009
The purpose of this study was to evaluate the accuracy of diffusion-weighted imaging (DWI) in diagnosis of pancreas cancer, to compare DWI with a conventional comprehensive MRI (MRI-c) and to analyse apparent diffusion coefficient (ADC) values of lesions.

Diffusion-weighted magnetic resonance imaging in the management of cholesteatoma

European Archives of Oto-Rhino-Laryngology, 2009
Diffusion-weighted (DW) MRI has recently increasingly gained popularity in the diagnosis of post-operative cholesteatoma. The aim of this study is to prospectively evaluate the usefulness of echo-planar imaging (EPI) for the diagnosis of residual cholesteatoma. Fifty patients underwent DW-EPI before surgery.
