Magnetization transfer ratio (MTR) has been used for assessment of macromolecules in biological tissues. Ultrashort echo time technique magnetization transfer (UTE-MT) can quantify both of short and long T2 tissues, may have potential to evaluate early disc herniation. The current study aims to assess the feasibility of UTE-MT quantification of posterior longitudinal ligament and nucleus pulposus for evaluation of early disc herniation. It was concluded that the UTE-MT sequence is feasible to quantify posterior longitudinal ligament and nucleus pulposus in lumbar. Posterior longitudinal ligament and nucleus pulposus UTE-MTR may provide a new opportunity for early prediction of lumbar disc herniation.
