Arterial spin labeling (ASL) has been a preliminary application in musculoskeletal perfusion analysis. However, it has not been applied to the spinal bone marrow (SBM) lesions in the literature up to date. First, this study investigate the effects of inversion time(TI) on flow-sensitive alternating inversion recovery(FAIR) perfusion imaging of SBM to find the optimized TI, then the correlation between ASL and dynamic contrast enhanced (DCE) magnetic resonance (MR) imaging in the measurement of SBM perfusion were assessed to analyse the feasibility of ASL SBM perfusion.
