Diffusion‐weighted MRI of fatty liver

Journal of Magnetic Resonance Imaging, 2011
AbstractPurpose:To investigate the effect of fat infiltration on the apparent diffusion coefficient (ADC) of liver, and assess the relationship between ADC and hepatic fat fraction (HFF).Materials and Methods:MRI scans of 120 consecutive patients were included in this retrospective study. Of these, 42 patients were included in the fatty liver group and

Diffusion-Weighted MRI

2003
Although conventional T2-weighted magnetic resonance imaging (MRI) is sensitive for the detection of multiple sclerosis (MS) lesions, it is not without important limitations. First, MRI lacks specificity with regard to the heterogeneous pathological substrates of individual lesions, and in consequence does not allow tissue damage to be quantified ...

Diffusion-weighted MRI in cervical cancer

European Radiology, 2008
The purpose was to investigate the potential value of apparent diffusion coefficient (ADC) measurement with MRI in the assessment of cervix cancer. Diffusion-weighted MRI was performed in 47 patients with cervical carcinoma undergoing chemoradiation therapy and 26 normal controls on a 1.5-T system with a b-value of 600 s/mm(2). FIGO stage, tumor volume,

Fiber Enhancement in Diffusion-Weighted MRI

2012
Diffusion-Weighted MRI (DW-MRI) measures local water diffusion in biological tissue, which reflects the underlying fiber structure. In order to enhance the fiber structure in the DW-MRI data we consider both (convection-)diffusions and Hamilton-Jacobi equations (erosions) on the space \mathbbR3 \rtimes S2Unknown control sequence '\rtimes' of 3D ...

Identification of “Premyelination” by Diffusion-Weighted MRI

Journal of Computer Assisted Tomography, 1995
The purpose of this study was to compare white matter maturation as demonstrated with diffusion-weighted MRI and with myelin-sensitive histological staining.The diffusion-, T1-, and T2-weighted SE MRI at 4.7 T was performed weekly in a total of 16 rat pups, aged from 5 days to 8 weeks, 2 animals evaluated per week.

Diffusion-Weighted MRI and Liver Metastases

Magnetic Resonance Imaging Clinics of North America, 2010
Liver metastases are the most frequently encountered malignant liver lesions in the Western countries. Accurate diagnosis of liver metastases is essential for appropriate management of these patients. Multiple imaging modalities, including ultrasound, CT, positron emission tomography, and MRI, are available for the evaluation of patients with suspected

Diffusion-Weighted MRI in the Diagnosis of Cholesteatomas

ORL, 2009
<i>Objective:</i> The diagnosis of a cholesteatoma can be difficult in cases with an intact tympanic membrane. The aim of our study was to examine whether diffusion-weighted MRI can confirm the diagnosis of a cholesteatoma. <i>Study Design:</i> A preoperative diffusion-weighted MRI (echo-planar imaging) scan of the temporal bone

Diffusion-weighted MRI in cortical ischaemia

Neuroradiology, 2004
We carried out MRI on 16 male and three female comatose patients, aged 2 days to 79 years, with suspected cortical ischaemia referred from our intensive care units. Using a head coil, and following standard imaging, including coronal fluid-attenuated inversion-recovery images, we performed diffusion-weighted imaging (DWI) using a whole-brain multislice

Conventional and Diffusion-Weighted MRI of the Hippocampus

2014
The human hippocampus is a highly complex structure located on the medial surface of the cerebral hemispheres as a part of the intralimbic gyrus. For clinical purposes, in addition to routine transverse MRI slices, acquisitions parallel and perpendicular to the long axis of the hippocampus need to be performed to fully appreciate its curved anatomy ...

The physical basis of diffusion-weighted MRI

Journal of the Neurological Sciences, 2001
Diffusion-weighted (DW) magnetic resonance imaging (MRI) is the only technique that permits a non-invasive in vivo assessment of water molecular diffusion, which reflects tissue configuration at a microscopic level. Therefore, this technique appears to be particularly useful in monitoring brain abnormalities.
