CT双能量技术在颅颈交界区韧带损伤诊断中的应用可行性分析

颅颈交界区是头颅向颈椎过渡的关键部位，该区域结构复杂，功能特殊。颅颈交界区韧带在维持颅颈部的稳定和正常旋转、屈伸运动中扮演着重要角色。颅颈交界区韧带损伤，轻则引起寰枕枢关节脱位，重则损伤延髓、颈髓引起瘫痪甚至危及生命。颅颈交界区韧带众多，位置深，相互重叠，其损伤诊断困难，成为临床和影像研究的热点和难点。本文通过对CT双能量技术在韧带损伤诊断中的应用可行性进行分析、综述，为颅颈交界区韧带损伤的临床诊断、治疗及预后评估提供技术支持和参考依据。

Feasibility analysis of diagnosis of ligament injury in the craniocervical junction with dual source CT

Craniocervical junction is the key transitional part from head to neck, which has complex structure and special functions. Craniocervical ligament plays an important role in maintaining the stability, normal activities, and flexion and extension of the head and neck. The ligaments injuries have great harm to the health of the body, including at-lantoaxial dislocation, injury of medulla oblongata resulting paralysis and even death. Craniocervical junction has lots of ligaments, which were distributed deeply and were overlapped with each other. The diagnosis of ligament injury in cra-niocervical junction is difficult, which attract great attention from clinical and imaging researchers. This review aims at providing a reference for clinical diagnosis, treatment and prognosis of ligament injury in craniocervical junction by ana-lyzing the feasibility of diagnosis of ligament injury with dual source CT.
