Abstract:
The values for regional cerebral blood flow at rest were obtained from 60 right handed normal Korean adults(48 males, 12 females) with an age range of 24 to 69 years. The results were summarized as follows. 1) Mean rCBF were Fg ; 74.8+/-13.3ml/100g/min., Fw ; 19.2+/-3.1ml/100g/min, Wg ; 44.0+/-5.4% and CBF(inf) ; 39.8+/-7.6ml/100g/min. 2) In normal regional flow distributions throughout each hemisphere, values of Fg, Fw and CBF(inf) were higher in the frontal lobes and lower in the parietal lobes. A trend for higher values for Wg was seen in occipital and temporal lobes and lower values in the frontal lobes of both hemispheres. 3) When normal limits of the interregional variety values were predicted as mean ICV+2 SD(p<0.05), those values were Fg ; 12%, Fw ; 12%, CBF(inf) ; 10%, FFg ; 4% and Wg ; 10% of mean hemispheric rCBF. 4) There was a significant progressive decline of parameters of Fg, CBF(inf) and Wg with advancing age.
