OBJECTIVE. : To determine how many thoracic scoliotic pedicles have cancellous versus cortical versus absent channels.
目的：对下颈椎椎弓根四壁及入口毗邻结构的皮质厚度行影像学测量，为临床椎弓根钉植入提供参考。
Objective: Cortex thicknesses of subaxial cervical pedicle entrys circumferential structures were measured on planar ct images to provide quantitative data for cervical pedicle screw insertion.
