Liver magnetic resonance diffusion weighted imaging: 2011 update

Clinics and Research in Hepatology and Gastroenterology, 2011
Diffusion-Weighted-Imaging (DWI) assesses proton motion on a cellular scale. Owing to recent instrumentation developments, diffusion sequences are now routinely used for liver imaging. This review will go through the physical principles that underlie this technique, and then highlight up-to-date liver applications including quantification of liver ...

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.

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.

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.

Central nervous system aspergillosis: magnetic resonance imaging, diffusion-weighted imaging, and magnetic resonance spectroscopy features

Acta Radiologica, 2006
Aspergillus infection is invasive in nature in the immunosuppressed population and disseminates throughout the body, with the brain being a common site. Conventional magnetic resonance imaging (MRI) combined with diffusion-weighted imaging (DWI) and magnetic resonance spectroscopy (MRS) play a life-saving role in the early diagnosis and treatment ...

Breast magnetic resonance imaging: diffusion-weighted imaging.

Magnetic resonance imaging clinics of North America, 2013
More imaging centers are incorporating diffusion-weighted imaging (DWI) into the clinical breast magnetic resonance (MR) examination, with the potential of increasing the specificity of breast MR imaging. This article reviews the role of DWI in the evaluation of breast lesions. The principles, technique, and protocol of DWI are discussed, including the

Isotropic anomalous filtering in Diffusion-Weighted Magnetic Resonance Imaging

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
Noise is inherent to Diffusion-Weighted Magnetic Resonance Imaging (DWI) and noise reduction methods are necessary. Although process based on classical diffusion is one of the most used approaches for digital image, anomalous diffusion has the potential for image enhancement and it has not been tested for DWI noise reduction.
