目的探讨脑血管疾病CT与MRI 诊断的价值。方法 对我院2013年1月至 2014年6月期间在我院诊治、临床怀疑为 脑血管疾病的78例患者分别行CT和MRI检 查，通过综合分析CT与MRI检查的影像特 点、检查成本，评价这两种方案的优越 性及实用性。结果 CT诊断结果显示：30 例为正常，18例为脑动脉瘤，脑动脉或脑 静脉畸形16例，脑烟雾病2例，4例脑动脉 炎，4例颈内动脉海绵窦瘘，4例脑动脉先 天性变异；MRI检查病变种类和病变检出 率与CT一致，但MRI影像表现显著优于CT 影像；MRI每检出1例脑血管疾病的成本为 776.95元，CT每检出1例脑血管疾病的成 本526.62元，MRI的诊断成本高于CT诊断 成本，差异具有明显的统计学意义。结论 单考虑诊断结果，MRI在诊断脑血管疾病 中具有更高的价值；综合考虑诊断成本因 素，对于微小病灶、不容易发现的病灶、 经济条件较好或很注重诊断效果的患者， MRI检查是首选方案；对于较大病灶的普 通脑梗塞或脑出血的患者，CT检查更优 越。

Objective To explore the diagnostic value of CT and MRI in cerebral vascular disease. Methods A total of 78 patients which suspected cerebral vascular disease from January 2013 to June 2014 were includeed into the study. The CT, MRI data and examination charges of 78 cases were analyzed, and the advantages and practicability were evaluated. Results CT diagnostic results showed 30 cases as normal, 18 patients with brain aneurysms, 16 cases of cerebral venous malformation of the cerebral artery, cerebral moyamoya disease 2 cases, cerebral arteritis 4 cases, internal carotid artery-cavernous sinus fistula 4 cases, congenital variations of cerebral arteries 4 cases; the MRI and CT had the same detection rate while MRI imaging performed significantly better than CT imaging. MRI examination cost 776.95 RMB one time fee, and CT cost 526.62 RMB, MRI charged higher than CT. Conclusion Only on consideration of diagnosis, MRI had higher value in the diagnosis of cerebral vascular diseases, considering the examination charge, for small lesions, favorable economic patients, or pay much attention to diagnosis patients, MRI examination is the first choice. For large area cerebral infarction and cerebral hemorrhage, CT is superior.
