磁共振弥散加权成像在超急性期脑梗死诊断中的应用分析

The Application of Diffusion Weighted Magnetic Resonance Imaging in the Diagnosis of Cerebral Infarction in Super Acute Stage

目的探究超急性脑梗死诊断中磁共振弥散加权成像（DWI）的应用情况。方法选择我院2013年1月~2016年8月收治的50例超急性期脑梗死患者,根据患者诊断方法的不同分为对照组和观察组,比较两组患者的确诊率及治疗效果,分析超急性期脑梗死患者的DWI信号特点。结果对照组患者的确诊率为84.00%,治愈率为56.00%;观察组患者的确诊率为92.00%,治愈率为72.00%,观察组患者的确诊率和治愈率高于对照组患者（P〈0.05）,差异具有统计学意义;超急性期脑梗死患者的DWI信号为高信号或稍高信号,与慢性期相比弥散系数降低,患侧平均弥散系数为（0.37±0.05）,健侧平均弥散系数为（0.94±0.10）。结论磁共振弥散加权成像在超急性其脑梗死临床诊断中具有较高的确诊率,早诊断早治疗,有效提高患者的治疗效果。

Objective To explore the diagnosis of hyperacute cerebral MR diffusion weighted imaging（DWI） of the application. Methods In our hospital from January 2013 to August 2016, 50 cases of hyperacute cerebral infarction patients were chosen, according to different methods in the diagnosis of patients into control group and observation group, compared two groups of patients with the diagnostic rate and therapeutic effect, analysis of DWI signal characteristics of patients with hyperacute cerebral infarction. Results The control group was 84.00% of patients diagnosed, the cure rate was 56.00%, the observation group were diagnosed was 92.00%, the cure rate was72.00% in the observation group of patients diagnosed and cure rate was significantly higher in patients（P〈0.05）, with statistical significance, DWI signal hyperacute cerebral infarction or slightly hyperintense signal, compared with chronic phase diffusion coefficient decreases ipsilateral average diffusion coefficient（0.37±0.05）, contralateral the average diffusion coefficient（0.94±0.10）. Conclusion DWI has a higher rate of diagnosis of their hyperacute cerebral infarction, early diagnosis and treatment, improve patient outcomes.
