摘要
目的评价在超急性和急性缺血性脑梗死鉴别诊断中应用磁共振弥散张量成像(DTI)的效果。方法回顾性分析2016年1月至2017年2月间于我院就诊的发病72 h以内、临床高度怀疑脑梗死的42例患者,比较患者病灶与对侧相应位置的DTI各项参数的差异,分析DTI用于超急性和急性缺血性脑梗死的诊断效能。结果42例患者中,超急性缺血性脑梗死患者16例,急性缺血性脑梗死患者20例,短暂性脑缺血发作6例。病灶区域的FA、ADC、DCavg和EA值与对侧对应区域存在明显差异(P<0.05);超急性期和急性期的病灶区域FA、ADC和DCavg值存在明显差异(P<0.05)。DTI对于超急性期脑梗死的诊断准确率为80.95%,灵敏度为81.25%,特异度为80.77%;对于急性期脑梗死的诊断准确率为95.24%,灵敏度为95.00%,特异度为95.45%。结论在早期临床高度怀疑脑梗死的患者中,应用DTI诊断超急性和急性缺血性脑梗死具有较好的诊断效能。
Objective To explore the efficacy of diffusion tensor imaging （DTI） in differential diagnosis of hyper-acute ischemic cerebral infarction （HAICI） and acute ischemic cerebral infarction （AICl）. Methods From January 2016 to February 2017, the DTI parameters of 42 highly suggestive AICI and HAICI patients were retrospectively analyzed, and the diagnostic efficiency of DTI for AICI and HAICI were analyzed. Results There were 16 cases of HAICI, 20 cases of AICI and 6 cases of transient ischemic attack （TIA）. There were statistical difference between lesions and contralateral position in the value of FA, ADC, DCavg and EA, also between AICI and HAICI in FA, ADC and DCavg （P 〈0.05）. The diagnosis accurate rate, sensitivity, specificity of DTI for HAICI were 80.95%, 81.25% and 80.77%, and for AICI were 95.24%, 95.00% and 95.45%. Conclusions For clinical diagnosis of highly suggestive ischemic cerebral infarction patients, DTI has good diagnostic efficiency on hyper-acute and acute ischemic cerebral infarction.
