And the relationship between vertebral body bone marrow fat and disc degeneration needs further clarification. In this study, quantitative synthetic MR technique as well as fat quantification MR technique are used to investigate relationship between imaging markers and degeneration levels. Results indicates intervertebral discs’ quantitative T2, T1 and PD values are significantly different among Pfirrmann grading groups. Significant negative correlations are found between Pfirrmann grading and quantitative values. T1 and PD values have weak correlation with bone marrow fat fraction.
