T1rho MRI in the lumbar spine may provide a tool for the diagnosis of early degenerative changes in the disc. In this study, the mean T1rho value of pilots was significantly lower than that of the control group. The degenerative grades of pilots mainly were grade III and IV, but control group were grade I and II. There were significant differences in T1rho values at each age group between pilots and control group. And overload on spine column of pilots may be the important reason in degeneration and accelerate the degeneration process.
