摘要
目的 对比研究脑电地形图(BEAM)、CT和TCD对缺血性脑血管病的诊断价值。方法 选择缺血性脑血管病发病七天以内的100例病人，进行BEAM、TCD和CT检查并对比分析其结果。结果 发病2天以内的病人，BEAM诊断为TIA者32例(82.1％)，脑梗塞者53例(86.8％)：TCD诊断为TIA者16例(41％)；未发现脑梗塞。CT既未发现TIA也未发现脑梗塞。发病3～7天以内的病人，BEAM发现TIA 36例(92.3％)，脑硬塞55例(90.1％)：TCD发现TIA 23例(58．0％)；脑梗塞51例(83.6％)；CT发现脑梗塞61例(100％)。结论 BEAM对缺血性脑血管病的诊断具有明显高于TCD和CT的阳性检出率．具有超前的诊断价值。
ve To study the diagnostic value with BEAM , TCD and CT on ischemic cerebrovascular disease. Methods 100 cases of ischemic cerebrovascular disease with 7 days illness were selected and given the examination of BEAM , TCD and CT , the results were analysed comparatively. Results 32 cases of patients with 2 days illness were diagnosed as TIA with BEAM (82%), 53 cases as infarction(86%), comparing with TCD only 16 cases as TIA (41%), none as TIA or infarction with CT . 36 cases of patients with 3 - 7 days illness were found as TIA with BEAM (92.3%), 55 cases as infarction(90.1%), 23 cases as TIA(58%) with TCD, 51 cases as infarction (83.6%) . 61 cases as infarction with CT(100%) . Conclusion BEAM has obviously higher positive detecting rate than TCD and CT does on ischemic cerebrovascular disease, and has early diagnostic value.
