目的研究脑分水岭梗死患者脑血管病变的特点.方法全部患者均选用飞利浦Achieva 3.T磁共振机进行MRI和MRA检查,标准患者头部正交线圈.常规检查扫面序列主要有T1 WI、T2WI、DWI.选用三维时间飞跃法进行MRA检查.结果 29例串珠样梗死灶患者中有27例为大血管病变,占93.1％;27例无串珠样梗死灶患者中检出18例为大血管病变,占66.7％.与无串珠样梗死灶患者相比,有串珠样梗死灶患者大血管出现病变可能性明显较高.结论脑部MRA对患者脑部大血管病变检查相对较高,且方法简单,对患者伤害较小,可作为临床脑分水岭梗死患者脑血管病变的主要检查方法.

Objective To study the characteristics of vascular lesions in patients with cerebral watershed infarction.Methods All patients selected Philips Achieva 3.T MRI machine for MRI and MRA examination, the patient' s head standard quadrature coil.Inspection sweep surface sequences were mainly T1WI, T2WI, DWI.MRA was performed by three-dimensional TOF.Results Among the 29 cases for species beaded infarction, there were 27 cases of large vessel disease, accounting for 93.1％;among the 27 cases of non-infarct patients beaded, there were 18 cases of large vessel disease, accounting for 66.7％.Compared with patients without infarction beaded with beaded infarction occurs in patients with large vessel disease was significantly higher possibility.Conclusions MRA of the brain in patients with cerebral vascular disease inspection is relatively high, and the method is simple, less harm to the patient, so it can be used as the main screening method in clinical cerebral watershed infarction and cerebrovascular disease.
