目的：探讨磁共振液体衰减反转恢复序列(fluid-attenuated inversion recovery,FLAIR)成像高信号血管征(hyperintense vessel sign,HVS)对急性大脑动动脉供血区脑梗死诊断中的作用。方法收集本院2010年至今表现为大脑中动脉区首次急性梗死患者MR影像资料，共35例，分为HVS阳性组(n=13)和HVS阴性组(n=22),比较两组患者扩散加权成像(DWI)上所示梗死体积大小、临床入院时NIHSS评分及早期神经功能恢复情况（早期神经功能恢复情况以入院时及入院10-14天患者的NIHSS评分差值衡量）。结果13例FLAIR序列远端HVS(37.1％)阳性患者平均梗死体积(76.49±28.72)mm3,入院时NIHSS平均评分[11(1-22)分]、入院10-14d NIHSS评分[7(0-21)分]、22例FLAIR序列远端HVS(37.1％)阴性患者中，平均梗死体积（97.69±30.26）mm3,入院时NIHSS平均评分[15(7-25)分]、入院10-14d NIHSS评分[13(4-25)分]，HVS阳性及阴性患者在梗死体积大小、临床入院时NIHSS评分及早期神经功能恢复情况均存在显著差异，具有统计学意义。结论磁共振FLAIR远端HVS，能较早提供急性脑梗死诊断及预后评估指标，指导临床治疗，对急性大脑中动脉供血区脑梗塞诊治具有重要意义。

Objective To explore the role of MRI sequences of fluid-attenuated inversion recovery (FLAIR) imaging hyperintense vessel signs (HVS) on diagnosis of acute cerebral artery blood supply zone infarction. Methods Collecting our hospital patients with acute infarction of middle cerebral artery area since 2010, a total of 35 cases, which were divided into the HVS positive group (n=13) and HVS negative groups (n=22).Two groups were compared with infarction volume size clinical NIHSS score on admission, and early neurologic recovery (early neural function recovery in patients on admission and admission 10-14 days of NIHSS score difference measure) by diffusion weighted imaging (DWI). Results 13 cases of distal HVS FLAIR sequences (37.1%) patients with positive average (76.49+28.72) mm3 infarction volume, average NIHSS score on admission (1-22) [11], hospital 10-14 d NIHSS score (0-21) [7], 22 cases of distal HVS FLAIR sequences (37.1%) negative patients, the average volume of infarction (97.69+30.26) mm3, average NIHSS score on admission [15 (7-25)], hospital 10-14 d NIHSS score [13 (4-25) points, HVS in patients with positive and negative in the infarction size, clinical NIHSS score on admission, and early neurologic recovery were significant difference and statistically significant. Conclusion MRI FLAIR distal HVS can provide early diagnosis and prognosis of acute cerebral infarction and guide clinical treatment, which is important for the diagnosis and thraphy of acute infarction of middle cerebral artery blood supply zone.
