原发脑干损伤影像学诊断及分类

目的：观察原发脑干损伤的影像学表现，研究其影像学诊断及分类。方法：对１００例临床诊断为原发脑干损伤病人伤后４８小时内行头颅ＣＴ扫描，其中１０例并进行了ＭＲＩ检查，对其影像学特点进行分析研究。结果：１００例ＣＴ扫描有脑干损伤直接征像９７例，间接征像９８例，无异常改变２例。１０例ＭＲＩ检查均有脑干损伤的直接征像。临床和影像学诊断脑干挫伤９４例，脑干血肿３例，脑干震荡２例。结论：ＣＴ、ＭＲＩ影像学检查能补充和完善既往的临床诊断标准，确定脑干损伤的部位、范围、程度和类型。

Radiological Diagnosis and Classification of Primary Brain Stem Injury

Objective: To investigate the radiological diagnosis and classification of primary brain stem injury (PBSI) by studying their radiological presentation.Methods: 100 cases PBSI diagnosed by clinical presentation had CT scanning within 48 hours after injury,10 of them took MRI.Their radiological features were studied.Results: 97 of 100 cases had the dirct CT scanning signs of PBSI,98 cases had indirect signs,while 2 had none.All the 10 cases took MRI had direct PBSI signs.94 cases were diagnosed clinically and radiologically to be brain stem contusion while 4 be brain stem hemostasis and 2 brain stem shock.Conclusion: By ensuring the location,extent,injure degree and classification of PBSI,CT MRI can significantly supplement and perfect the former clinical diagnostic standard of PBSI.
