Recently, several techniques for rapid simultaneous mapping of proton density and T1, T2 relaxation parameters from a single acquisition and generation of synthetic images of any desired image contrast have been demonstrated, mostly in the brain. Such an approach could potentially shorten a spine MRI exam which typically consists of multiple 2D acquisitions with different contrast weightings. But even routine spine MRI is fraught with technical challenges such as motion and inhomogeneity. So in this work we explore the feasibility of obtaining synthetic MRI images of usable image quality in the spine using a 2D quantitative mapping technique.
