摘要 目的:探讨磁敏感加权成像序列在急性弥漫性轴突损伤诊断中的应用价值。方法 :分析经临床和影像证实的急性弥漫性轴突损伤27例患者磁共振资料,包括常规T1WI、T2WI、液体衰减反转恢复序列以及磁敏感加权序列。分别比较各序列对弥漫性轴突损伤出血性病灶的检出数目,并分析其分布特点和信号特征。结果:弥漫性轴突损伤病灶主要分布在脑白质、基底节区、皮髓交界区、胼胝体、小脑及脑干等区域,磁敏感加权成像术上呈结节状、斑点状、条索状及小片状低信号灶。磁敏感加权成像术对出血性弥漫性轴突损伤病灶的检出率最高,与其它序列比较差异均有统计学意义(P<0.05)。结论:磁敏感加权成像序列对出血性弥漫性轴突损伤的诊断敏感性较高,可为临床早期诊断提供可靠的影像学依据,应作为磁共振检查弥漫性轴突损伤的常规和首选序列。
