OBJECTIVE: To study changes in cerebral hemodynamics related to HIV infection. BACKGROUND: Cerebral injury is a well-known manifestation of HIV infection. Physiologic changes in the HIV brain may precede structural changes and may be detected by functional MRI (fMRI). METHODS: Dynamic contrast fMRI was used to measure the cerebral blood volume (CBV) in 13 patients infected with HIV and in 7 healthy control subjects. RESULTS: Significant increases in dynamic CBV were found in the deep (p < ...Expand abstract
