| 摘 要： | 目的 探讨MRI在轻型颅脑损伤诊断中的作用。方法 回顾分析近 2年 9例诊断为轻型颅脑损伤患者 ,伤后不同时期颅脑CT扫描及MRI检查的资料。结果 9例患者伤后多次颅脑CT检查均为正常 ,而MRI检查表现为出血性改变 4例 ,T1W像为高信号 ,T2W像为高信号 ;表现为非出血性改变 5例 ,T1W像为等信号 ,略低信号 ,T2W像及液体衰减反转恢复序列 (fluid -attenuatedinversionrecovery ,FLAIR)为高信号。 结论 在轻型颅脑损伤诊断中MRI检查能提高出血性病灶及非出血性损伤的检出率 ,并可以避免一些漏诊。

| Abstract: | Objective To investigate the significance of MRI scan in the diagnosis of minimal brain injury. Methods The clinical data of 9 cases with minimal brain injury diagnosed by CT and MRI scan were reviewed retrospectively. Results In 9 cases, CT images indicated normal tissue after injury times without number, but MRI images showed hemorrhagic contusion in 4 cases (hyper-intense signal lesions both on T1WI and T2WI) and non- hemorrhagic contusion in 5 cases(iso-intense or slight hypo-intense signal on T1WI, hyper-intense signal on T2WI and FLAIR sequence). Conclusions MRI scan may enhance the detecting rate of hemorrhagic contusion obviously, and diminish the rate misdiagnosis. |
