目的分析磁共振弥散加权成像(DWI)技术在超急性期脑梗死诊断中的价值,了解超急性期脑梗死发病与诊断。方法对56例超急性期脑梗死患者6h内就诊时均首先经头颅CT扫描,然后进行MRI平扫和弥散成像(DWI)扫描,然后对可疑患者24h后复查,对其结果进行分析总结。结果 56例超急性期脑梗死患者24h确诊脑梗死CT扫描13例占23.2%,MRI常规扫描46例占82.1%,DWI扫描56例占100%。结论 DWI可以明确诊断超急性期脑梗死,同时有助与临床治疗。
Objective To analyze the value of magnetic resonance diffusion-weighted imaging (DWI) in the diagnosis of hyperacute cerebral infarction and to understand the pathogenesis and diagnosis of hyperacute cerebral infarction. Methods Fifty-six patients with hyperacute cerebral infarction were examined by skull CT scan within 6 hours and then scanned by MRI and diffusion imaging (DWI). The suspicious patients were reviewed after 24 hours and the results were analyzed and summarized. Results In 56 cases of hyperacute cerebral infarction, 13 cases were diagnosed cerebral infarction CT scan in 23 cases, 46 cases in MRI scan accounted for 82.1%, DWI scan in 56 cases accounted for 100%. Conclusion DWI can clearly diagnose hyperacute cerebral infarction, and help with clinical treatment.
