In this study, we retrospectively analyzed the imaging data of spinal tumors to find out more imaging features of spinal tumors, in order to provide more accurate reference for the diagnosis of spinal tumors.

Bone tumors account for 1-2% of total body tumors, and spinal tumors only account for 6.5% of total body tumors. Because of the low incidence rate, the number of patients and the attention in this field are far lower than other tumors, so far, all the researches on spinal tumors are relatively lacking. Because the diagnosis of bone tumor needs the combination of clinical, imaging and pathological to make a more accurate diagnosis, so the imaging diagnosis of spinal tumor is very important. In this study, through retrospective analysis of a variety of imaging data of patients with spinal tumor, measurement and recording of spinal tumor image related parameters, and statistical analysis, in order to find out more imaging characteristics of patients with spinal tumor, more accurate diagnosis of lesions, and provide more help for clinical decision-making.

Inclusion Criteria:

• Complete and accurate clinical and pathological data are available；Imaging examination was performed in our hospital

Exclusion Criteria:

• Patients with missing image data and unclear image
