摘　　要：目的判断T2加权梯度回波（GRE-T2WI）通过检测脑微出血来预测高血压性脑出血患者血肿扩大的可行性。方法选取2011年6月至2014年6月我院收治的高血压性脑出血患者107例为研究对象,患者均进行CT及GRE-T2WI检查,判断其是否存在脑微出血,并于入院后24小时及72小时复查CT观察血肿变化情况。结果 107例患者中通过GRE-T2WI检查发现,共有56例患者存在脑微出血。72小时CT显示,脑微出血患者中19例血肿进展,发生率为33.9%;无微出血患者中5例进展,发生率为9.8%。脑微出血患者72小时后血肿扩大4～19 m L,平均（13.2±3.5）m L;无微出血患者血肿扩大1～16 m L,平均（9.7±3.4）m L。两类患者血肿进展率及血肿扩大量相比,差异具有统计学意义（P〈0.05）。结论通过GRE-T2WI观察高血压性脑出血患者是否存在脑微出血,对预测患者是否存在继续出血意义重大,可根据GRE-T2WI结果给予及早干预,减少血肿进一步扩大可能。Objective To estimate the feasibility of gradient recalled echo-T2WI（GRE-T2WI） in predicting hematoma enlargement of patients with hypertensive cerebral hemorrhage by detecting cerebral microbleeds. Methods 107 cases of patients with hypertensive cerebral hemorrhage treated in our hospital from June 2011 to June 2014 were selected as research objects. All patients were implemented CT examination and GRE-T2 WI examination to determine whether existing cerebral microbleeds, and received CT reexamination after admission for 24 h and 72 h to observe the changes of hematoma. Results The results of GRE-T2 WI examination on 107 patients showed that 56 patients existed cerebral microbleeds. The CT in 72 h showed that patients with cerebral microbleeds had hematoma development in19 cases, with the incidence was 33.9%; patients without cerebral microbleeds had hematoma development in 5 cases, with the incidence was 9.8%. The hematoma of patients with cerebral microbleeds enlarged 4 ～ 19 m L, with the average was（13.2 ± 3.5） m L; the hematoma of patients without cerebral microbleeds enlarged 1 ～ 16 m L, with the average was（9.7 ± 3.4） m L. The hematoma development rate and hematoma enlargement of two types patients had statistically significant difference（P〈0.05）. Conclusions To observe whether patients with hypertensive cerebral hemorrhage exist cerebral microbleeds by GRE-T2 WI has important significance in predicting whether patients exist continuous hemorrhage. We can give early intervention to patients according to the results of GRE-T2 WI, and reduce the probability of further bleeding.
