Abstract
There is a growing interest in the tomographic measurement of regional cerebral blood flow and oxygen utilisation using continuous inhalation of C15O2 and 15O2. This paper examines the influence of certain assumptions in the underlying steady-state model. Estimations are made for possible errors in the actual measurement of these quantities in grey and white matter.
摘要
使用连续吸入C15O2和15O2对局部脑血流量和氧利用率进行断层测量的兴趣与日俱增。本文研究了基础稳态模型中某些假设的影响。对灰质和白质中这些量的实际测量中可能出现的误差进行了估计。
