摘要
目的:探讨磁共振(MRI)弥散加权成像(DWI)在颅内表皮样囊肿诊断及鉴别诊断中的价值。方法:回顾性分析15例手术病理证实的颅内表皮样囊肿的术前MR常规平扫、增强和DWI资料。结果1:3例T1WI呈低信号,2例T1WI呈混杂稍高信号;T2WI呈高信号;DWI均表现为明显高信号;增强多无强化。结论:在颅内表皮样囊肿影像诊断及鉴别诊断中DWI均有特异性,应该在颅内占位性病变中作为常规扫描技术。
Objective To investigate the magnetic resonance（MR） diffusion-weighted imaging（DWI） in diagnosis of intracranial epidermoid cyst and differential diagnosis.Methods Retrospective analysis of 15 cases of pathologically confirmed intracranial epidermoid cysts routine preop-erative MR scan,enhance and DWI information.Results of 13cases T1WI low signal,and 2 cases T1WI showed slightly mixed signal;T2WI showed high signal;DWI showed high signal is apparent;enhanced multiphoton no enhancement.Conclusion In the imaging diagnosis of in-tracranial epidermoid cyst and differential diagnosis of DWI are specific,should be in intracranial space-occupying lesions as a conventional scanning techniques.
