摘要 目的 探讨SPECT和CT对老年急性脑梗死病人检查的异同和优缺点,以指导临床诊断和治疗。方法 对同一患者在发病后3d内进行CT和SPECT检查。结果 CT的病灶检出率为54%,SPECT为92%,两者存在相关关系(χ² =0.953,P >0.1),SPECT检出率高(χ² =30.422,P <0.05);SPECT可发现远隔损害。结论 SPECT可对老年急性脑梗死作出预警性诊断,发现的病灶更易解释临床症状;CT可发现小的深部梗死灶,可清晰地鉴别脑出血和脑梗死;两者不能互相替代。

Abstract Objective Toinvestigate thedifferences of brain ⁹⁹ Tc^m -ECD SPECT and X-CT inexamining elderly patients with acute cerebral infarction thus to guide clinicaldiagnosisand treatment.methods 100 elderly patients with acute cerebralinfarction underwent ⁹⁹ Tc^m -ECD SPECT and X-CT between 1996 and1997.On each patient,the two procedures were performed sequentially within threedays.Results Thepositive rate of X-CT was 54%,while the positive rate of SPECT was 92%.The results of X-CTcorrelated with the results of SPECT (χ² =0.953,P >0.1),andthe positive rate of SPECT was higher (χ² =30.422,P <0.05).SPECTshowed not only primary ischemic lesions,but also remote consequential lesions.Conclusions ⁹⁹ Tc^m -ECDSPECT is better at predictivediagnosis of elderly acute cerebral infarction and gainvaluable time for in-time treating,and it ismore sensitive fordetecting and localizing thelesions andmakes the interpretation of clinical symptoms and signs easier.X-CT ismoresensitive todetect basal ganglionic lacunar infarction and todistinguish cerebralinfarction from cerebral hemorrhage.SPECT and X-CT can not be used in place of each other.
