椎管内神经源性肿瘤MR诊断价值

目的:对椎管内神经源性肿瘤的影像表现进行分析,探讨神经源性肿瘤的MR表现特征及诊断价值。方法:经手术病理证实神经源性肿瘤13例,所有病例均采用自旋回波T1加权及T2加权序列进行扫描,常规行矢状位扫描,必要时加扫轴位和/或冠状位。所有病例均通过MR图像对肿瘤的部位、形态、大小、边界、信号、是否发生坏死囊变、椎间孔改变及增强后强化情况各方面进行观察分析。结果:13例神经源性肿瘤中发生于颈、胸椎7例,肿瘤呈长圆形5例,9例肿瘤引起椎间孔扩大,肿瘤信号呈等T1信号8例,长T1信号3例,短T1信号2例,等T2信号3例,长T2信号10例,病灶内发生斑点状坏死2例,斑片状坏死3例,明显囊变1例,8例经增强扫描病例呈明显不均匀强化5例,均匀强化3例。结论:椎管内神经源性肿瘤具有特征性MR表现,通过MR表现可做出正确的诊断,并根据这些特征性表现可与其他一些椎管内肿瘤进行鉴别诊断。

Intravertebral duct neurogenic tumor of MR diagnostic value

Objective:For the neurogenic tumor image analysis,summarizes neurogenic cortical tubers characteristics and diagnostic value.Methods:After surgical pathology neurogenic tumor 13 cases,all cases were adopted to spin echo T1-weighted and T2 weighted scan sequence,conventional sagittal scan line position,when necessary,and added axis and/or coronal.All the cases of cancer by MR images of the shape,size,site,boundary,signal,or necrosis capsule,and change of pore after observing all aspects of strengthening case...
