摘要
目的:总结使用对顺磁性物质最为敏感的EPI-FE-T2WI序列的脑内血肿的表现及演变规律。方法:收集有明确发病时间的脑内血肿病人共148例,使用EPI-FE-T2WI序列进行头部扫描。结果:超急性脑内血肿28例(超急性脑梗塞溶栓后出血9例,自发性脑出血19例,),急性脑内血肿25例,亚急性早期23例,亚急性晚期27例,慢性期及软化灶期52例。结论:脑内血肿在MRI均具有特征性和演变规律。MR使用EPI-FE-T2WI序列结合常规序列能够独立诊断脑内血肿并进行分期。充分掌握血肿的演变规律有助于简便、迅速、准确的进行诊断和鉴别诊断,并有助于脑内血肿期龄的准确判断。
Objective:To summarize the echo plannar imaging field echo T2 * WI (EPI-FE) sequence manifestation of all stages intracranial hemorrhage (ICH) and variation regularity. Methods: 148 intracranial hemorrhages were examinated by echo plannar imaging echo field echo T2 * WI (EPI-FE) sequence of high field MR . Results : 28 hyperacute ICH, 25 acute ICH, 23 earlier period subacute ICH, 27 late period subracute ICH, 52 chronic ICH were examinated. Conclusion: All stages intracranial hemorrhage (ICH) had imaging characteristic and variation regularity on high field, use echo plannar imaging field echo T2 * WI(EPI-FE) sequence and routine sequences of hfigh field MR can diagnosis ICH independently and distinguish stage. The variation regularity has assistance to the diagnesis of ICH and the definition of ICH stage.
