Abstract

A three-dimensional image registration technique for CT and MR studies of the cervical spine was evaluated for feasibility and efficacy. Registration by means of external fiducial markers was slightly more accurate than registration by anatomic landmarks. The interrelationships between bony (eg, neural foramina) and soft tissue structures (eg, nerve roots) in the cervical spine were more conspicuous on registered images than on conventional displays. Registration of CT and MR images may be used to examine more precisely the relationships between bony and soft tissue structures of the cervical spine.

摘要

对一种用于颈椎CT和MR研究的三维图像配准技术的可行性和有效性进行了评估。通过外部基准标记进行的配准比通过解剖标志进行的配准略准确。与传统显示相比,颈椎中骨结构(如神经孔)和软组织结构(如神经根)之间的相互关系在配准图像上更为明显。CT和MR图像的配准可用于更精确地检查颈椎骨结构和软组织结构之间的关系。
