BACKGROUND AND PURPOSE It is unclear why only some patients with lacunar infarction and radiological evidence of diffuse white matter abnormalities have dementia. The purpose of this study is to investigate the value of callosal atrophy as an indicator of cognitive impairment. METHODS We used magnetic resonance imaging to evaluate 11 right-handed male patients with lacunar infarction and exte...

Introduction: Malignant gliomas are currently evaluated by subjective assessment of T2and contrast-enhanced T1-weighted imaging. Glioblastoma multiforme (GBM) is largely considered a single clinical entity for the purposes of treatment rationalisation, although genetic biomarkers which predict response to treatment in glioma from biopsy samples have been discovered. Non-invasive imaging biomark...

Magnetic resonance imaging (MRI) is a well-established imaging modality to evaluate increased iron deposition in the liver. Both standard liver imaging series with in-phase and out-of-phase T1-weighted sequences for visual detection, as well as advanced T2- and T2*-weighted measurements may be used for mapping the iron concentration. In this article, we describe different forms of liver iron ac...

A giant vertebral notochordal rest is a newly described, benign entity that is easily confused with a vertebral chordoma. As microscopic notochordal rests are rarely found in adult autopsies, the finding of a macroscopic vertebral lesion is a new entity with only seven previously presented cases. We report here radiological findings, including diffusion weighted images, of a patient with a gian...

A 63-year-old man presented with painless jaundice, loss of appetite and significant weight loss. Cross-sectional imaging showed a diffusely enlarged pancreas, with no significant fat stranding and a hypodense rim on computed tomography, which appeared hypointense on T2-weighted magnetic resonance imaging. There was a narrowed pancreatic duct and features of common bile duct narrowing in the re...

We analyze a diffuse interface type approximation, known as the diffuse domain approach, of a linear coupled bulk-surface elliptic PDE system. The well-posedness of the diffuse domain approximation is shown using weighted Sobolev spaces and we prove that the solution to the diffuse domain approximation converges weakly to the solution of the coupled bulk-surface elliptic system as the approxima...

this presentation aims to focus on different types of sub arachnoid hemorrhage (diffuse ,central and perimesencephalic) with different etiology and their important imaging considerations that are important to know when a radiologist encounter to a case of sub arachnoid hemorrhage.
