腰椎+骶骨读片part2——CT

本文共有5张中英文标注图片,第一张是定位图,其余4张为CT轴位图像。共41个标注结构,学习一遍大概需要20分钟。如果之前看了颈胸椎体的话,估计5分钟就足够了~脊椎关节都有类似的结构。

The annulus fibrosus 发音见这里is the tough circular exterior of the intervertebral disc that surrounds the soft inner core, the nucleus pulposus. This outer portion is composed of a ring of ligament fibers that encases the inner core of the disc and securely connects the spinal vertebrae above and below the disc.

 

下一个部分将更新腰骶部MRI线片,敬请期待~
