探讨磁共振弥散加权成像(DWI)对于超急性期脑梗死的临床诊断价值。收集脑梗死患者60例,采用常规MRI及DWI检查,分析其影像学诊断结果。DWI对超急性期脑梗死的诊断准确率为100.00%,显著高于MRI的48.00%(P<0.05);超急性期脑梗死相对表现弥散系数显著高于急性期、亚急性期和慢性期(P<0.05)。DWI对于超急性期脑梗死的诊断效能优于传统MRI,对于临床早期诊断及治疗决策具有重要价值。
To investigate the value of magnetic resonance diffusion-weighted imaging (DWI) in the diagnosis of hyperacute cerebral infarction. Sixty patients with cerebral infarction were collected and analyzed by conventional MRI and DWI. The diagnostic accuracy rate of DWI for hyperacute cerebral infarction was 100.00%, which was significantly higher than that of MRI (48.00%) (P <0.05). The relative diffuse coefficient of infarction in hyperacute acute phase was significantly higher than that in acute phase, subacute phase and chronic phase P <0.05). DWI is superior to traditional MRI in diagnosis of hyperacute cerebral infarction, which is of great value in early clinical diagnosis and treatment decision-making.
