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
