摘 要: | 目的探讨磁共振神经成像对外周神经鞘膜瘤诊断的临床价值。材料与方法回顾性分析27例经手术和病理证实的外周神经鞘膜瘤资料,所有病例均行MRI常规成像和结合短TI反转恢复时间成像(3D-STIR)增强序列扫描。分析和评价3D-STIR增强扫描序列对外周神经鞘膜瘤诊断的可行性和准确性,比较常规MRI成像及3D-STIR序列增强扫描对外周神经鞘膜瘤诊断的征象和价值。结果27例外周神经鞘膜瘤患者,磁共振常规成像可以显示病灶的部位、数目、形态、体积、信号特征。3D-STIR增强扫描序列上均可清晰显示周围神经走行及病变同周围神经关系。结论磁共振常规序列及3D-STIR增强扫描序列对外周神经鞘膜瘤的定位定性诊断有重要的临床应用价值。

Abstract: | Objective:To investigate the clinical value of magnetic resonance neurography (MRN) in diagnosis of peripheral nerve sheath tumors. Materials and Methods: Twenty-seven patients with peripheral nerve sheath tumors proved by surgery and pathology underwent MRI conventional scanning and contrast-enhanced short TI reverse recovery time sequence (3D- STIR) scanning. The accuracy and feasibility of contrast-enhanced 3D-STIR scanning in peripheral nerve sheath tumors were retrospectively analyzed and evaluated. The diagnostic signs and the value of MRI conventional scanning and contrast-enhanced 3D-STIR scanning were compared. Results:In these cases, MRI conventional images can display the location, number, shape, size and signal characteristics of lesions, and contrast-enhanced 3D-STIR images can display the relevance between lesions and spinal nerves clearly. Conclusion:MRI conventional scanning and contrast-enhanced 3D-STIR scanning have important clinical value in diagnosing peripheral nerve sheath tumors. |
