目的明确常规磁共振对于血管高信号的展示及其临床意义。方法回顾总结浙江大学医学院附属第一医院2010年1-12月的急性缺血性卒中患者。所有患者均行常规磁共振检查。结果我院神经内科共收住急性脑梗死患者280例，均符合脑血管病诊断标准。血管内异常信号患者共26例，出现率为9.29％。前循环异常信号14例，其中颈内动脉高信号11例，大脑前动脉高信号2例，大脑中动脉合并大脑前动脉高信号1例；在颈内动脉血管内高信号11例患者中，MRA证实14支颈内动脉血管狭窄，对血管病变的特异度100％，敏感度78.6％；后循环共12例，其中椎动脉高信号5例，基底动脉3例，基底动脉合并椎动脉高信号4例；1例患者未行MRA检查，11例患者MRA证实14支血管存在病变，椎动脉和基底动脉内高信号11例，特异度为100％，敏感度为78.5％。结论常规磁共振序列对于血管内高信号的展示具有很高的临床特异度，其血管病变与MRA的结果具有一致性。

Objective To define the high intraarterial signals on conventional MRI. Methods Review the conventional MRI data in all of the acute ischemic stroke patients in the First Affiliated Hospital,School of Medicine, Zhejiang University from January 2010 to December 2010. Results In year 2010,according to the diagnostic criteria of China, there were 280 cases of acute cerebral infarction, all underwent conventional MRI. Twenty six patients (9. 29％ ) showed high intraarterial signals on conventional MRI.There were 14 cases with high signals in the anterior circulation, including 11 cases in the carotid artery, 2 cases in the anterior cerebral artery, and 1 case in the middle cerebral artery combined with the anterior cerebral artery. In the 11 patients with high signals in the carotid artery, MRA confirmed 14 internal carotid arteries stenosis, with 100％ specificity and 78.6％ sensitivity. There were 12 cases with high signals in the posterior circulation, including 5 cases in the vertebral artery, 3 cases in the basilar artery, and 4 cases in the basilar artery with vertebral artery. One patient did not undergo MRA. MRA confirmed 14 arteries with stenosis, with 100％ specificity and 78.5％ sensitivity. Conclusions Intravascular high signals showed by conventional MR sequences have high clinical specificity, and its vascular lesions are consistent with the results of MRA.
