Ultrashort echo time magnetization transfer (UTE-MT) is suggested to a non-invasive technique to assess collagenous matrix indirectly. In this study, we utilized UTE-MT sequence to investigate the relationship between UTE-MT ratio (UTE-MTR) measurements of paraspinal muscles and disc herniation in patients with disc degeneration. We found that the UTE-MTR showed a good performance in differentiation of patients with and without disc herniation, thus potentially valuable in predicting disc termination.
