摘要 目的探讨磁敏感加权成像在脑微出血诊断中的应用价值。方法选取我院收治的120例疑似脑微出血患者为研究对象,对120例疑似脑微出血患者分别行MRI常规序列扫描以及SWI序列扫描,对检出CMBs阳性例数、脑微出血灶位置分布情况、脑微出血灶数量的显示情况进行比较。结果 90例患者通过SWI检测均显示出磁敏感效应,SWI主要表现为条状、点状以及类圆形等,检出率为100%;86例常规序列检出CMBs阳性,检出率为76.5%,二者具有显著性差异(P<0.05)。90例患者中通过T1WI序列扫描表示病灶显示不明显,通过T2WI序列扫描共检出232个低信号灶。SWI序列共检出1 392个低信号灶。结论磁敏感加权成像技术具有高度的敏感性,在现阶段的临床应用中可检出脑微出血的最佳序列,从而更好的为临床治疗提供参考。
