BACKGROUND AND PURPOSE Deposition of iron has been recognized recently as an important factor of pathophysiologic change including neurodegenerative processes in multiple sclerosis (MS). We propose that there is an excess accumulation of iron in the deep gray matter in patients with MS that can be measured with a newly developed quantitative MR technique--magnetic field correlation (MFC) imagin...

Purpose: This study is designed to determine the sex differences in brain weight and volume of left hemisphere and its gray and white matters in right-handed normal subjects and the right-handed subjects which were suffered from Alzheimer and Parkinson diseases. Materials and Methods: This study was performed on 72 normal human brains (38 male, 34 female), 11 brains suffered from Alzheimer (4 ...

Minimum spanning tree and normalized cut based segmentation method are evaluated with respect to segmentations made by humans. The segmentation error is determined by two discrepancy measures, as a sum of miss-counted segmented pixels. Gray value images are used for the evaluation. This benchmarking is well suited in finding the class of images best suited for a particular method.

Acute regional cerebral ischemia was produced in the middle cerebral artery (MCA) territory in monkeys (Macaca mulatta) by selective embolization of the internal carotid (ICA) bifurcation with minimum surgical intervention in the neck under sedated conditions. Two of five hours after embolization, brain water (measurement of dry weight) and tissue concentration of sodium and potassium were dete...

In multiple sclerosis (MS), the correlation between lesion load on conventional magnetic resonance imaging (MRI) and clinical disability is weak. This clinico-radiological paradox might partly be due to the low sensitivity of conventional MRI to detect gray matter demyelination. Magnetization transfer ratio (MTR) has previously been shown to detect white matter demyelination in mice. In this st...
