摘要: 选择高血压脑出血患者94例作为研究对象,全部患者接受T1加权成像(T1-weighted imaging,T1WI)、T2加权成像(T2-weighted imaging,T2WI)和敏感加权成像(sensitive weighted imaging,SWI)三种序列的磁共振加权成像检查。结果显示,SWI序列的早期诊断率明显高于T1WI、T2WI序列(P<0.05)。最终检出125个出血灶,SWI序列的出血灶阳性率明显高于T1WI、T2WI序列(P<0.05)。T1WI、T2WI序列显示边界清晰的高信号影;SWI序列显示的出血灶边界、范围等均较T1WI、T2WI序列更清晰。本研究证实SWI对高血压脑出血患者的早期诊断效果较好,可准确反映出血灶数量,且图像质量较高。

Abstract: The 94 patients with hypertensive intracerebral hemorrhage were selected as subjects. All patients underwent T1WI, T2WI and SWI weighted magnetic resonance imaging. The results showed the early diagnosis rates of SWI sequences were significantly higher than those of T1WI and T2WI sequences. 125 cases of hemorrhage were finally detected. The positive rates of hemorrhagic foci in SWI sequences were significantly higher than T1WI and T2WI sequences. T1WI and T2WI sequences showed high signal shadows and clear boundaries, SWI sequence showed a clearer boundary and range of bleeding foci than T1WI and T2WI sequences. The value of SWI in the early diagnosis of hypertensive intracerebral hemorrhage is satisfying, which can accurately detect the hemorrhage foci, and has high image quality.
