简要总结
Observational study
The purpose of this observational study was to understand the quantitative assessment of the degree of degeneration of lumbar facet joints, and to improve the Weishaupt grading system by using gray-scale curve fitting and imaging parameters.
The main questions it aims to answer are: How to realize quantitative analysis of lumbar facet joint degeneration in patients with chronic low back pain with MRI?
The MRI information of patients with different grades of articular process joint degeneration has been statistically summarized in nearly 5 years

时间窗: "From enrollment to the end of treatment at 1 weeks
Based on the signal intensity changes of T2-weighted of 1.5T MRI in different degenerative grades of facet joints, the gray value changes in facet joints were measured and fitted.
