多层螺旋CT灌注成像、彩色脑电地形图、视觉诱发电位及其地形图在急性脑梗死诊断中的对比研究

A comparison study of multislice CT perfusion imaging,color brain atlas,visual evoked potential mapping and other atlas in the diagnosis of acute cerebral infarction

目的 比较多层螺旋CT灌注成像 (multisliceCT perfusionimaging ,MSCTPI)、彩色脑电地形图 (colorbrainatlas,CBA)、视觉诱发电位及其地形图 (visualevokedpotentialmapping ,VEP M )在急性脑梗死诊断中的价值。方法 2 0 0 0 - 0 8～ 2 0 0 3- 0 8河北医科大学附属第四医院神经内科对 2 7例临床诊断为急性脑梗死的患者 ,行常规CT平扫后分别进行MSCTPI、CBA、VEP M检查。结果 MSCTPI表现为与临床症状相对应的灌注缺损区 ;CBA表现为在Scale为 32时 ,病变区δ、θ频带出现局限性高功率阴影 ;VEP M表现为在曲线图中P10 0的潜伏期延长、病变侧波幅降低 ,其地形图功率值分布表现为病变部功率值较对应部位明显降低 ,分布不对称。结论 MSCTPI、CBA、VEP M联合应用 ,可弥补三种检查方法各自的不足 ,进一步提高急性脑梗死的诊断率。

Objective Compare the value of multislice CT perfusion imaging (MSCTPI)?color brain atlas (CBA)?visual evoked potential mapping (VEP-M) in the diagnosis of acute cerebral infarction.Methods After routine CT was performed,the 27 cases of acute cerebral infarction underwent MSCTPI?CBA?and VEP-M respectively.Results The examination of MSCTPI showed that abnormal perfusion changes were in accordance with clinical symptoms;the examination of CBA showed that in 32 scale local high power shadow presented on the power of δ?θ of lesion;the examination of VEP-M showed the prolongation of latency of P100?degrade of amplitude on the lesion of the chart,the power of the lesion degraded obviously on the map of distribution of power,and distribution asymmetry.Conclusion Combined use of MSCTPI?CBA?VEP-M in the diagnosis of acute cerebral infarction can remedy the defects and improve diagnostic rate of acute cerebral infarction further.
