Author contributions: Xu W, Wang SL, Xiong MY, Wang Y, Yu QF, Ye XJ and Li ZK designed the research study; Xu W, Wang SL, Xiong MY and Li ZK performed the research; Wang SL and Xiong MY performed magnetic resonance imaging (MRI); Li ZK, Wang Y, Yu QF and Ye XJ analyzed the data and wrote the manuscript. All authors have read and approve the final manuscript. Xu W and Xiong MY are co-first authors. This paper has two corresponding authors because it involves two professional fields: Spinal Surgery and Radiology. The two corresponding authors are from these two departments respectively. This paper requires the professional knowledge of both Spinal Surgery and Radiology. The expert in Spinal Surgery is responsible for the collection of clinical data, the diagnosis of adjacent segment disease patients and case analysis. The expert in Radiology is responsible for the parameter setting of artifact-removed MRI and the measurement of imaging parameters. Their joint participation ensures the comprehensiveness and scientificity of this study. Therefore, Wang SL and Li ZK are listed as co-corresponding authors.

Core Tip

Core Tip: WARP magnetic resonance sequences can significantly reduce the artifact area in the sagittal and cross-sectional planes of titanium alloy spinal fixation, and the advantage of eliminating artifacts in the sagittal plane is more obvious. The resolution of the vertebral body, pedicle, intervertebral foramen, nerve root canal and herniated nucleus pulposus was significantly improved, which made the structures in the intervertebral space of the adjacent vertebrae clearly visible, providing a good imaging reference for the diagnosis of adjacent segment disease.
