摘要:
目的 探讨磁共振弥散加权成像（DWI）对超急性期脑梗塞的诊断价值。方法 收集2018年1月~2019年3月本院接收的40例经脑血管造影确诊且行DWI扫描的急性脑梗塞患者临床资料，比较急性期与超急性期患者的肿瘤表观扩散系数（ADC），分析DWI对超急性期脑梗塞的检出率及诊断价值。结果 超急性期脑梗塞患者的患侧ADC值高于急性期患者，差异有统计学意义（P＜0.05）。40例患者中有26例诊断为超急性期患者，诊断符合率为92.86%（26/28）；11例诊断为急性期，符合率为91.67%（11/12）。DWI诊断超急性期脑梗塞的灵敏度为92.86%、特异度为91.67%、准确度为92.50%、阳性预测值为96.30%、阴性预测值为84.61%。结论 DWI诊断超急性期脑梗塞可准确显示其病灶，具有较高灵敏度、特异度及准确度，可为临床治疗提供重要参考依据。
Abstract:
Objective To explore the value of magnetic resonance diffusion weighted imaging (DWI) in the diagnosis of hyperacute cerebral infarction. Methods The clinical data of 40 patients with acute cerebral infarction diagnosed by cerebral angiography and DWI scans received in our hospital from January 2018 to March 2019 were collected, and the tumor apparent diffusion coefficient (ADC) of patients in the acute phase and hyperacute phase was compared,to analyze the detection rate and diagnostic value of DWI for hyperacute cerebral infarction.Results The ADC value on the affected side of patients with hyperacute cerebral infarction was higher than that of patients with acute phase,the difference was statistically significant (P＜0.05). Of the 40 patients, 26 were diagnosed as hyperacute patients, and the diagnostic coincidence rate was 92.86% (26/28); 11 patients were diagnosed as acute, with a coincidence rate of 91.67% (11/12). The sensitivity of DWI to diagnose hyperacute cerebral infarction was 92.86%, specificity was 91.67%, accuracy was 92.50%, positive predictive value was 96.30%, and negative predictive value was 84.61%.Conclusion DWI diagnosis of hyperacute cerebral infarction can accurately display its focus, with high sensitivity, specificity and accuracy, and can provide an important reference for clinical treatment.
