The current study demonstrated the feasibility of quantitative evaluation of human IDD in vivo by R2*, UTE-T2* and T1rho mapping. We found that T1rho value is superior to UTE-T2* and R2* values for differential diagnosis of the early IVD, while UTE-T2* value is optimal for differential diagnosis of advanced IVD. T1rho mapping can be considered an effective tool for distinguishing IDD at the earlier stage of the degenerative process.
