OBJECTIVE: Cavernous malformations are angiographically occult cerebrovascular malformations
found in approximately 0.5% of the population. To help further understand the natural …

PURPOSE: To categorize leukoencephalopathies of unknown origin into a few major
groups by using magnetic resonance (MR) imaging criteria to facilitate further studies, and to …

BACKGROUND Brain stem tumors in children have been classified pathologically as low
grade or high grade gliomas and descriptively as diffuse gliomas, intrinsic gliomas, midbrain …

Evidence from numerous structural magnetic resonance imaging (MRI) studies has
converged to implicate mesial temporal lobe structures in the pathophysiology of several …

Object. Although cavernous malformations (CMs) are not detected in angiographic studies,
they have a characteristic appearance on magnetic resonance (MR) images. A number of …

Quantitative, single‐voxel proton NMR spectroscopy of normal brain was performed in five
adult beagle dogs using the cerebral water signal as an internal intensity reference. The …

Individuals with Down syndrome (DS), a disorder of known genetic etiology (trisomy of
chromosome 21), exhibit several types of structural brain abnormalities that are detectable …
