目的 分析CT和MRI在脑血管疾病(CVD)中的诊断有效性及效果。方法 回顾性分析2015年1月-2017年1月我院88例 CVD患者的临床资料，其中脑梗死40例，脑出血38例，动脉瘤10例，先后CT及MRI检查，对比不同CVD类型患者的 CT与MRI诊断的符合率。结果 MRI对脑梗死患者的诊断符合率(100.00%)高于CT(85.00%)，差异具有统计学意义 (P<0.05)；MRI与CT对脑出血与动脉瘤的诊断符合率对比差异无统计学意义(P>0.05)。结论 MRI与CT在CVD诊断中各 具优势，其中对于微小病灶、不易发现的病灶结合患者的经济能力可选用MRI。

Objective To investigate the diagnostic effectiveness and effect of CT and MRI in cerebrovascular disease (CVD). Methods The clinical data of 88 patients with CVD in our hospital from January 2015 to January 2017 were analyzed retrospectively, included 40 cases of cerebral infarction, 38 cases of cerebral hemorrhage, 10 cases of aneurysm. Both of them were examined by CT and MRI respectively. The coincidence rate of CT and MRI in the patients with different CVD types was observed and compared. Results The diagnostic accuracy of MRI in patients with cerebral infarction was higher than that of CT (100.00% vs. 85.00%), the difference was statistically significant (P<0.05). There was no significant difference in the comparison of the coincidence rate between MRI and CT in the diagnosis of cerebral hemorrhage and aneurysm (P>0.05). Conclusion MRI and CT have respective advantages in CVD diagnosis. For small lesions and difficult to detect lesions, MRI can be selected combined with the economic ability of patients
