MRISUMMARY Aims: The purpose of this paper is to investigate the effect of bevacizumab (BEV) on the diffusion properties of irradiated brain gliomas. Materials & methods: Neuroimaging studies and medical records of 44 patients undergoing treatment for cerebral gliomas were reviewed. MRIs were ...
Cell walls form barriers to the diffusion of water molecule and so the more cells, the more barriers. If the packing density is very efficient, then the amount of extracellular space (where diffusion is normally freer) is also reduced. Uniform small round or hexagonal cells (as seen in ...

One such condition is acute encephalopathy with biphasic seizures and restricted diffusion also called as acute leukoencephalopathy with restricted diffusion. Here, the routine MRI sequences such as T1, T2, and fluid-attenuated inversion recovery sequences can be normal. Here, we have reviewed the ...
Infarction of the corpus callosum is rare, and other conditions can cause magnetic resonance imaging (MRI) restricted diffusion in the callosum, leading to diagnostic uncertainty. We sought to characterize the etiology of lesions with diffusion restriction in the corpus callosum. Methods Callosal lesion...

Several investigations into the sites of action of opioid analgesics have utilized peripherally acting mu-opioid receptor antagonists (PAMORAs), which have been incorrectly assumed to possess limited permeability across the blood-brain barrier. Unfortuna
The query parameters were age 7 to 13 years, IQ greater than 70, and structural MRI present. The minimum age was set as 7 years because that was the age of the youngest participant made available by the ABIDE Consortium. Additionally, the maximum age was capped at 13 years Supekar and...
We investigated IL-6 associations with age in T1-weighted segments and microstructural diffusion indices using MRI in aged rhesus monkeys (Macaca mulatta). Further, we determined if long-term 30% calorie restriction (CR) reduced IL-6 and attenuated its association with lower tissue volume and ...
