Cerebral Blood Flow Measurement Using fMRI and PET: A Cross-Validation Study
fMRI PET Cerebral Blood Flow Measurement
2009/9/4
An important aspect of functional magnetic resonance imaging (fMRI) is the study of brain hemodynamics, and MR arterial spin labeling (ASL) perfusion imaging has gained wide acceptance as a robust and...

We investigated whether rCBF values obtained with the SPECT technique are different in schizophrenics with predominantly positive or negative symptoms and assessed the biological underpinnings of psyc...
Measurement of cerebral blood flow in rats and mice by hydrogen clearance during hyperbaric oxygen exposure
CO2 carbon dioxide hydrogen hyperbaric cerebral blood flow air animal mice
2009/6/8
The hydrogen (H2) clearance method was adapted for the measurement of regional cerebral blood flow (rCBF) in anesthetized rats and mice during hyperbaric oxygen (HBO2) exposure. Polarographic platinum...
Will prior hyperventilation reduce cerebral blood flow during escape from a submarine?
decompression submarin cold exercise decompression
