Neuroradiologists may encounter, on a daily basis, a challenging diversity of neurologic
disorders, including stroke, trauma, epilepsy, and even neurodegenerative conditions, such as …

Purpose: The objective of this study was to separate multiple signal components present in
functional MRI (fMRI) data sets. Blind source separation techniques were applied to the …

PURPOSE: To determine the clinical utility of gadolinium-enhanced fluid-attenuated
inversion-recovery (FLAIR) magnetic resonance (MR) imaging of the brain by comparing results …

PURPOSE To evaluate the spatial specificity of functional MR imaging by comparing it with
intraoperative electrocortical mapping. METHODS Functional MR imaging was performed in …

BACKGROUND AND PURPOSE: No widespread clinical method provides specific information
about the angiogenic characteristics of gliomas. We characterized blood volume and …

OBJECTIVE: To illustrate how lesion-induced neurovascular uncoupling at functional
magnetic resonance imaging (fMRI) can mimic hemispheric dominance opposite the side of a …

Neuroradiologists generally do not fully appreciate the importance of the territory of the
ascending pharyngeal artery. The ascending pharyngeal artery is a small but important artery …

This study demonstrates normal white matter structures of the supratentorial system revealed
by diffusion tensor imaging. Their anatomic connections and functional significance are …

A left-handed patient with a grade II left frontal lobe astrocytoma had spontaneous seizures
causing speech arrest and uncontrolled right upper extremity movements. Word-generation …

BACKGROUND AND PURPOSE In Gilles de la Tourette syndrome, PET scanning and EEG
suggest an abnormal organization of the sensorimotor cortex and basal ganglia. The …
