Background Focal dystonia is a neurological disorder characterized by unwanted muscle
spasms. Blepharospasm is a focal dystonia producing an involuntary closure of the eyelid. Its …

BACKGROUND: Several lines of evidence suggest that autism may be associated with
abnormalities in white matter development. However, inconsistencies remain in the literature …

MION‐46L, a superparamagnetic iron oxide contrast agent, was investigated for its ability to
increase the sensitivity of in vivo 3D MRI in the detection of brain lesions in a chronic …

BACKGROUND AND PURPOSE To determine whether occult disease fluctuates with
macroscopic lesions during the natural history of multiple sclerosis (MS) and whether therapeutic …

Purpose: Typically, the final step in volume registration is the reslicing of the volume of interest.
The purpose of this work is to examine the effects of this reslicing on functional MRI (fMRI…

A robust, automatic volume registration algorithm based on intensity gradients is presented.
This algorithm can successfully perform registrations under conditions of unrelated …

Studies with functional magnetic resonance (MR) imaging produce large unprocessed raw
data sets in minutes. The analysis usually requires transferring of the data to an off-line …

BACKGROUND AND PURPOSE: Although the exact nature of the physiological differences
between normal and multiple sclerosis (MS) brains are unknown, it has been shown that …

Purpose To investigate whether the method of applying image masks can alter quantifiable
measures determined from whole‐brain MTR calculations. Materials and Methods Thirty‐five …

A biomembrane sample system where millimolar changes of cations induce reversible large
scale (≥ 200 Å) changes in the membrane-to-surface distance is described. The system …
