Global cerebral blood flow was significantly lower in Rett syndrome (54 vs 69 mL/100 g per minute), and the flows in prefrontal and(More)

To assess the regional changes in cerebral blood flow, 10 healthy volunteers were given 400 micrograms thyrotropin-releasing hormone iv in a double-blind, randomized, cross-over study. Regional cerebral blood flow was determined simultaneously in two slices of the brain, using a single photon emission computerized tomograph and inhalation of 133Xe.(More)
