老年缺血性中风的CT、SPECT及临床

The relationship among manifestatons on CT,SPECT and clinical features in elderly ischemic stroke patients

目的用头颅ＣＴ和ＳＰＥＣＴ观察比较老年缺血性中风的临床表现、治疗和预后情况，比较二者的异同和优缺点，以及ｒＣＢＦ、ＣＴ病灶与脑功能改变之间的内在联系。方法对９０例临床诊断的老年缺血性中风患者同时进行头颅ＣＴ和ＳＰＥＣＴ检查，并与临床症状、体征进行相关研究。结果９０例老年缺血性中风患者的头颅ＣＴ及ＳＰＥＣＴ异常率分别为７４．４４％和９５．５５％；ＣＴ、ＳＰＥＣＴ病灶和临床的符合率分别为６８．２０％和９７．５６％。结论ＳＰＥＣＴ可以对早期中风患者做出预警性诊断，并可以发现ＣＴ所不能发现的远隔损害。ＳＰＥＣＴ比ＣＴ对老年缺血性中风的诊断阳性率高且出现早。

Objective The relationships among manifestations on CT, SPECT and clinical features in elderly ischemic stroke patients were investigated. [WT5”HZ〗Methods 90 patients with ischemic stroke were diagnosed by CT,SPECT or clinical criteria. All patients had CT scan and SPECT examinations within one week after admission. The results of CT, SPECT and clinical features were analyzed. Results The abnormality rates on CT and SPECT were 74.44% and 95.55% respectively. Difference between two variables was significant(P<0 05). The coincidence rates of CT,SPECT foci with clinical features was 68.02% and 97.56% respectively. Difference between two variables was also significant(P<0 05). Conclusion SPECT is more sensitive than CT in early diagnosis of ischemic stroke of elderly patients. Remote lesions can be defected by SPECT but not CT.SPECT can also be used as a valuable tool for the evaluation of treatment and prognosis.
