摘要
本文总结了低场ＭＲＩ误诊的颅脑、椎管内肿瘤２０例，分析了误诊原因。认为误诊原因有：①低场ＭＲＩ系统组织分辨率和空间分辨力低于中高场ＭＲＩ。②肿瘤ＭＲＩ表现缺乏特征性，不同肿瘤可出现相同信号及强化特征。③诊断医生经验不足，对少见肿瘤缺乏足够认识。
A total or 20 cases of intracranial or intraspinal tumors that were diagnosed incorrectly by MRI were summerized.It was found that the causes of incorrect diagnosis on MRI include:①The tissue resolution and spatial resolution of low field strength MR imaging system is lower than that of high field strength MR imaging system.②MR appearances of intracranial and intraspinal neoplasms are nonspecific to histologic diagnosis. The same signal intensities or enhancing patterns may appear in different types of tumor,③Lack of sufficient experience,the authers have not enough knowledge about rare tumors
