脑血流图作为一种简便易行而又无痛苦的脑血管病辅助诊断方法,近年来日益受到重视.但不同型号的脑血流图机,其工作频率、电桥精密度各不相同;各作者使用的电极形状、大小,以及受检者所取的体位等也都有差别;大家所采用的指标也不统一,甚至对同一指标的生理意义的看法也不甚一致.为此,本文拟将河南地区191名正常人的脑血流图结果进行分析,以求得出正常值范围,同时对有关问题进行讨论.
As a simple, convenient and painless diagnosis method of cerebrovascular disease, cerebral blood flow diagram has been paid more and more attention in recent years, but different types of cerebral blood flow chart machine have different operating frequency and bridge precision. The shapes and sizes of the electrodes used by the authors, as well as the position taken by the subject also have differences; the indicators used by everyone are not unified and even the physiological meaning of the same indicator is not very consistent.To this end, It is planned to analyze the results of cerebral blood flow tests in 191 normal people in Henan Province in order to find the normal range and to discuss the related issues at the same time.
