Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

facet joint degeneration

based on the Weishaput grading system, we classified all included patients into the facet joint degeneration group and divided them into four subtypes according to different grades.

MRI

Intervention Type DIAGNOSTIC_TEST

Based on the different manifestations of facet joints under MRI, and with the help of the characteristic manifestations of the gray value curve of facet joints under different subtypes, the curve of facet joints under the same level is fitted, and finally the accurate evaluation of different subtypes of small joints is achieved.
