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. ...

The same is true for diffusion restriction and ADC values on mpMRI; therefore, mixed tissue probably has higher ADC values [33]. Alternatively, a cumulative reduction of diffusion is typical of the aggressive disease being related to a dense growth pattern (Supplemental Fig. 4A-D). We showed...
Here, we describe a case of a female patient who presented to our center after being found unresponsive with magnetic resonance imaging (MRI), revealing bilateral basal ganglia diffuse restriction hyperintensities secondary to a diagnosis of opioid overdose. Opioid overdose-induced bilateral basal ...
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 ...
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...

Material and Methods: We performed conventional MRI including T1, T2-Weighted and DOI fluid attenuated inversion recovery (FLAIR) sequences and DWI in 16 patients with viral encephalitis & 02 patients of hypoxic ischaemic encephalopathy diagnosed on the basis of laboratory, clinical and radiologic ...
Diffusion-Weighted MRI in Predicting the Efficacy of Neoadjuvant Chemotherapy of Breast Cancer. Objective: To approach the apparent diffusion coefficient(ADC) obtained on diffusion weighted imaging (DWI) in predicting the response of breast cancer to neoadjuvant chemotherapy. Methods: 53 locally advanced ...
