周围神经三维重建与可视化研究进展

RESEARCH PROGRESS ON THREE-DIMENSIONAL RECONSTRUCTION AND VISUALIZATION OF PERIPHERAL NERVE

目的对周围神经三维重建与可视化研究进展进行综述。方法广泛查阅近期国内外周围神经三维重建与可视化研究的相关文献,并进行回顾和综合分析。结果利用周围神经三维重建与可视化技术,不仅可以真实再现周围神经复杂的三维表面结构及毗邻关系,而且可以将周围神经内部的三维结构任意显示、旋转、缩放、分割和适时三维测量,并已经在臂丛神经、腰骶丛神经、神经干功能束(组)、肌内神经走行分布、周围神经再生过程、包含周围神经的复合组织三维重建与可视化研究等方面取得了初步成效。但由于周围神经信息的识别、分割、配准和融合等问题尚未解决,周围神经可视化研究目前仍处于初始阶段。结论周围神经三维重建与可视化研究对更新周围神经损伤的诊疗理念、完善周围神经诊疗手段,开辟周围神经科研与教学的新途径等方面均具有重要的价值,可望成为周围神经外科新的生长点。

Objective To review the research progress on the three-dimensional （3D） reconstruction and visualization of peripheral nerve. Methods Literature about the research on the 3D reconstruction and visualization of peripheral nerve both at home and abroad were extensively reviewed and thoroughly analyzed. Results The application of 3D reconstruction and visualization technology was capable of not only reappearing the 3D outer contour and spatial adjacent relationship of peripheral nerve veritably but also displaying, rotating, zooming, dividing and real-time measuring their 3D internal structure and the delicate pathways in any direction either separately or totally. Preliminary achievements were achieved in terms of brachial plexus, lumbosacral plexus, the functional cluster of nerve trunk, intramuscular nerve distribution pattern, peripheral nerve regeneration and the 3D reconstruction and visualization research of complex tissue including peripheral nerve. However, the research on the visualization of peripheral nerve was still in the initial stage since such problems as recognition, segmentation, registration and fusion of the peripheral nerve information were not resolved yet. Conclusion Researching 3D reconstruction and visualization of the peripheral nerve is of great value for updating the diagnosis and treatment principle of peripheral nerve injury, improving its diagnosis and treatment method and launching a new way for the studying and teaching, which may be a new growing point for the peripheral nerve surgery.
