目的探讨CT与MRI对脑梗死的 诊断价值对比。方法 选取本院脑梗死患 者76例作为研究对象，均行CT和MRI诊 断，并分析检查结果。结果 本组76例 脑梗死患者，MRI对脑梗死病灶的检出率 为94.74%显著高于CT64.47%，检出病灶 数较CT多，差异显著(P<0.05)；MRI对 ＜6h、6-24h时间段脑梗死的检出率分别 为90.03%、97.22%均显著高于CT，差异显 著(P<0.05)。结论 与CT相比，MRI对早期 脑梗死的检出率较高。

Objective To investigate the value of CT and MRI in the diagnosis of cerebral infarction. Methods 76 patients with cerebral infarction in the hospital were selected as the research objects. All the objects received CT and MRI diagnosis and the results were analyzed. Results Among the 76 cases of cerebral infarction patients, the detection rate of MRI for cerebral infarction lesions was 94.74% which was significantly higher than 64.47% of CT and the number of detected lesions was higher than that of CT. The differences were significant (P<0.05). The detection rates of MRI for cerebral infarction during the period that was shorter than 6h and during 6 to 24h were 90.03% and 97.22%, respectively which were significantly higher than those of CT. The difference was significant (P<0.05). Conclusion Compared with CT, the detection rate of MRI for early cerebral infarction is higher.
