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=0953,P>01),SPECT检出率高(χ2=30422,P<005);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。
Objective To investigate the differences of brain 99 Tc m ECD SPECT and X CT in examining elderly patients with acute cerebral infarction thus to guide clinical diagnosis and treatment Methods 100 elderly patients with acute cerebral infarction underwent 99 Tc m ECD SPECT and X CT between 1996 and 1997 On each patient, the two procedures were performed sequentially within three days Results The positive rate of X CT was 54%, while the positive rate of SPECT was 92% The results of X CT correlated with the results of SPECT (χ 2=0 953,P>0 1), and the positive rate of SPECT was higher (χ 2=30 422, P<0 05) SPECT showed not only primary ischemic lesions, but also remote consequential lesions Conclusions 99 Tc m ECD SPECT is better at predictive diagnosis of elderly acute cerebral infarction and gain valuable time for in time treating, and it is more sensitive for detecting and localizing the lesions and makes the interpretation of clinical symptoms and signs easier X CT is more sensitive to detect basal ganglionic lacunar infarction and to distinguish cerebral infarction from cerebral hemorrhage SPECT and X CT can not be used in place of each other
