腰椎间盘突出症及腰椎管狭窄症常表现为反复发作的腰腿痛，椎间盘源性疼痛继发于椎间盘退变，
而椎间盘退变也可以导致椎间盘的突出，症状明显的病人甚至无法工作。所以如何精确判断椎间盘退变的程
度、怎样预防或适时的干预则显得尤为重要。磁共振技术比较简便且可以准确判断髓核退变的分级，而病理学
可以验证或判断磁共振的准确性。所以本文对腰椎间盘退变的MＲI 表现与病理变化之间的关系进行了系统的
描述，这样有助于MＲI 对椎间盘退变的早期诊断，并为临床疗效及预后评价奠定了基础。

Lumbar disc herniation and lumbar spinal stenosis often manifested as recurrent low
back pain，discogenic pain secondary to intervertebral disc degeneration，and intervertebral disc degeneration
can also lead to the intervertebral disc prominent，obvious symptoms of the patient even can not
work． Therefore，how to accurately determine the extent of disc degeneration and how to prevent or
timely intervention is particularly important．MＲI technique is simple and accurate for grading the degeneration
of nucleus pulposus．However，Histopathology can be used to verify and judge the accuracy of
MＲI．So this acticle describes the relationship between pathology features and MＲI changes of lumbar
disc degeneration，which helps MＲI in early diagnosis of intervertebral disc degeneration，and to lay a
foundation for the clinical curative effect and prognosis evaluation．
