摘要
本文分析了27例(34个)亚急性及慢性硬膜下血肿在SE多回波、SE—T_1WI和快速RARE—T_2加权序列中的信号特征及在不同成像平面中的形态学特征。充分肯定了MRI 在显示血肿的敏感性和精确性方面明显优于CT。对于血肿引起的占位效应的显示,MRI 也明显优于CT.结合文献,对自发性硬膜下血肿的形成机制进行了讨论。
MR signal and morpholosic features in 27cases(including 34 lesions)of subacute and(?)onic subdural hematomas were evaluated.The pu(?) sequences used in this study were SEmult(?)ho,SE-T_1WI and heavily T_2-weightedRARE(rapid acquisition with relaxation enhancement).MR imaging was superior to CT insensitivity,accuracy and demonstrating ocupying effect.The literature is reviewed,and themechanism of spontaneous subdural hematomasis discussed.
