BACKGROUND: Functional imaging studies indicate that imbalances in cortico-limbic activity
and connectivity may underlie the pathophysiology of MDD. In this study, using functional …

The mechanisms by which antidepressant-induced neurochemical changes lead to physiological
changes in brain circuitry and ultimately an antidepressant response remain unclear. …

Cross-correlation of low-frequency temporal fluctuations (<0.08 Hz) was used to correlate
widely separated anatomic regions during continuous performance of a spatial working …

The use of cerebral water as an internal intensity standard for the quantitation of spatially
localized proton spectra of the human brain is investigated. The method is validated on …

PURPOSE: To study the correlation of low-frequency blood oxygenation level–dependent (BOLD)
fluctuations on magnetic resonance (MR) images obtained of the left- and right-…

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

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

Perineural spread of head and neck tumors is a form of metastatic disease in which tumor
disseminates to noncontiguous regions along the endoneurium or perineurium. Both …

Functional magnetic resonance imaging (FMRI) has been successfully used to non‐invasively
map language function, but has several disadvantages. These include severe motion …

A variety of lesions may occur in the jugular foramen, arising from the structures normally
found within the jugular foramen or from contiguous structures. The most common jugular …
