The components of the intervertebral disk serve two purposes. The hydrophilic matrix is contained by circumferential rings of fibrocartilage (outer anulus) and Sharpey's fibers. The gellike hydrophilic matrix acts as a cushion between the vertebral body endplates by providing an even distribution of axial and rotational compressive forces. The construction and integrity of the intervertebral disk are assessed well by MR. The purpose of this pictorial essay is to show the in vitro and in vivo MR appearances of the normal and degenerated disk, and to correlate these MR changes with their respective histopathologic findings.
椎间盘的组成部分有两个作用。亲水性基质由纤维软骨（外环）和Sharpey纤维的环形结构所包裹。凝胶状的亲水性基质通过均匀分布轴向和旋转压缩力，在椎体终板之间起到缓冲作用。磁共振成像（MR）能很好地评估椎间盘的结构和完整性。本图文综述的目的是展示正常和退变椎间盘的体外和体内MR表现，并将这些MR变化与其各自的组织病理学结果相关联。
