目的 研究CT和MRI在脑血管疾病 中的诊断有效性及其效果，为临床提供依 据。方法 选取2014年3月-2016年3月医院 诊治的96例脑血管疾病患者资料进行研 究，入院后对患者先行CT检查，然后采用 MRI检查，比较CT和MRI在脑血管疾病中 的诊断有效性及效果。结果 CT、MRI及 CT+MRI在脑出血诊断中差异无统计学意义 (P>0.05)；MRI及CT+MRI在脑梗死、动脉 瘤诊断中差异无统计学意义(P>0.05)； MRI及CT+MRI在脑梗死、动脉瘤诊断阳性 率，显著高于CT(P<0.05)；MRI诊断方法 每例诊断成本及诊断总成本，显著高于CT 诊断(P<0.05)。结论 与单一的CT和MRI相 比，脑血管疾病患者采用CT联合MRI诊断 效果理想，能提高临床确诊率，值得推广 应用。

Objective To study the CT and MRI diagnostic validity and effect in cerebrovascular diseases for clinical basis. Methods March 2014-96patients data cerebrovascular disease in March 2016 to study the hospital for treatment, the patient admitted to hospital after first CT scan, then using MRI, CT and MRI diagnosis in comparison cerebrovascular disease valid nature and effect. Results CT, MRI and CT + MRI in the diagnosis of cerebral hemorrhage was no significant difference (P>0.05). MRI and CT + MRI in cerebral aneurysm diagnosis was no significant difference (P>0.05). MRI and CT + MRI in cerebral aneurysm diagnostic yield was significantly higher than CT (P<0.05). MRI diagnostic method for diagnosis of costs and the total cost per patient diagnosis was significantly higher than CT diagnosis (P<0.05). Conclusion Compared with a single CT and MRI, patients with cerebrovascular disease diagnosis using MRI over CT combined effect, can improve the clinical diagnosis rate, it should be widely applied.
