A few interesting tumors, including lymphomas and some highly malignant gliomas, may show significant restriction of diffusion and thus appear remarkably bright on DW images. The ADC values of tumors is inversely correlated with cellularity. Cell walls form barriers to the diffusion of water ...
The vast majority of neoplasms do not restrict diffusion or change it only mildly. A few interesting tumors, including lymphomas and some highly malignant gliomas, may show significant restriction of diffusion and thus appear remarkably bright on DW images. ...
Marked reduction in tissue diffusion occurs much less commonly than diffusion prolongation, but when it occurs it can have a dramatic effect on the diffusion-weighted MR images, rendering the abnormal areas "light-bulb bright". Diseases where this may occur include acute ischemia, infections, absces...
(DW-MRI) for up to 6 h following clot placement. SD is the mechanism of the cytotoxic edema of developing infarction that is diagnosed by DW-MRI, and DW-MRI also captures transient diffusion restriction caused by SD in less injured or healthy brains. Here, images (b = 0, 375, ...

DTI and fat-suppressed T2-weighted scans of the forearms were performed on a 3.0T MRI scanner. Fibre tractography of the median and ulnar nerves was performed to extract diffusion parameters: fractional anisotropy (FA), mean (MD), axial (AD) and radial (RD) diffusivity. Cross-sectional ...
To assess the capability of multimodal apparent diffusion (MAD) weighted magnetic resonance imaging (MRI) to distinguish between malignant and benign breast lesions, and to predict Ki-67 expression level in breast cancer. This retrospective study was con
Bevacizumab is an anti-vascular endothelial growth factor (VEGF) antibody with activity against recurrent malignant glioma inducing high rates of objective responses as assessed by magnetic resonance imaging (MRI). However, the mechanisms of the anti-tumor action of bevacizumab are controversial. In par...
