Objective To investigate the value of the susceptibility weighted imaging and T2*mapping imaging in the early diagnosis and grading evaluation of lumbar intervertebral disc degeneration.〖WTHZ〗Methods A total of 42 patients(117 lumbar intervertebral discs) of nonspecific low back pain with indications of MRI in first hospital affiliated to AMU from July 2016 to April 2017 were selected.The 117 lumbar intervertebral discs were divided into 3 groups based on the Pfirrmann classification standard

then based on the SWI classification standard

the semiquantitative classification was divided into three levels.T2*values of each intervertebral disc were measured by T2*mapping

and the correlation was analyzed.Results There was a statistically significant difference in the SWI grading between groups of lumbar intervertebral discs（P<0.01）

there was a good grade correlation between each group and SWI grading（r=0.786，P＜0.01）

two methods of evaluating the degree of lumbar intervertebral disc degeneration were more consistent（Kappa=0.716）.T2* values were negatively correlated with Pfirrmannbased classification and SWI classification（P＜0.01）.Conclusion Susceptibility weighted imaging and T2*mapping imaging can be used to evaluate the degeneration of lumbar intervertebral disc and early diagnosis.
