摘要

对４８例脑外伤患者进行了９９ｍＴｃ－ＥＣＤＳＰＥＣＴ脑血流灌注显像。其中４１例在ＳＰＥＣＴ检查的前后两周内同时行脑ＣＴ检查。结果ＳＰＥＣＴ对轻、中、重型脑外伤的检出率分别为６０％（６／１０）、９０％（１０／１１）和１００％（９／９）；而ＣＴ分别为１０％（１／１０）、６０％（６／１０）和１００％（９／９）。同一病人中ＳＰＥＣＴ比ＣＴ发现的病灶早、数目多（前者为７４，后者为３６）、范围大。对脑外伤综合征及后遗症ＳＰＥＣＴ检出率分别为８０％和９０％；ＣＴ分别为２５％和７１．４２％，显然ＳＰＥＣＴ探测脑外伤的灵敏度高于ＣＴ，但特异性不如ＣＴ。提示两种技术联合应用能更确切地反映脑外伤的病理、生理改变和进一步提高方法的灵敏度与特异性，对指导治疗更有意义。

Abstract

? Cerebral blood flow perfusion SPECT imaging with 99m Tc-ECD were studied in 48 patients of cerebral trauma

among them 41 cases also performed CT within 2 weeks of SPECT imaging. The results showed that the detection rate of SPECT and CT for mild

moderate and severe cerebral trauma were 60%（6/10）

90%（10/11）

100%（9/9） and 10%（1/10）

60%（6/10）

100%（9/9） respectively. Besides

detection rate of SPECT and CT in cerebral trauma symdrome and sequela groups were 80%

90% and 25%

71% respectively. Apparently

the sensitivity of SPECT was higher than CT but not the specificity. However

the more earlier the appearence of the lesion site

the more sites and extent of the lesion will be find in SPECT than CT. It was concluded that through the combined use of these two technologies

the pathophysiologic changes of cerebral trauma can be accurately reflected

their sensitivity and specificity further elevated

thereby have more significance for therapeutic guiding.
