Abstract

A computer assisted method of exact automatic measurement of BAEPs, mainly for the purpose of localization of brain-stem lesions, is described. The method presents analogue curves with superimposed confidence regions for the amplitudes and peak latencies of separate waves. The numerical output presents peak latencies, amplitudes, interpeak time intervals and central conduction times, all with normative values (60 healthy subjects), and +/- 2 and +/- 3 S.D. intervals and automatic labelling of pathological parameters (outside the chosen statistical limits). With the exception of the identification of separate waves in the often greatly distorted pathological BAEP the whole processing and display of the results are fully automatic.

摘要

描述了一种计算机辅助的脑干听觉诱发电位(BAEPs)精确自动测量方法,主要用于脑干病变的定位。该方法呈现出模拟曲线,并叠加了各个波的振幅和峰潜伏期的置信区间。数值输出包括峰潜伏期、振幅、峰间时间间隔和中枢传导时间,均带有标准值(60名健康受试者)以及±2和±3标准差区间,并自动标记病理参数(超出选定的统计界限)。除了在通常严重扭曲的病理BAEP中识别各个波外,结果的整个处理和显示都是完全自动的。
