## It is shown how Crame Β΄r-Rao theory may be used to determine Here we use the theory of Crame Β΄r-Rao lower bounds (5the optimal sampling pattern for measuring the NMR spin-spin 8) to determine the optimum choice of sampling times for relaxation time, T 2 . The results may also be applied to the
## Abstract __T__~1~ and __T__~2~ can be rapidly determined with a combination of multiangle spoiled gradient recalled echo (SPGR) and steadyβstate free precession (SSFP) imaging. Previously, we demonstrated a simple method for determining the set of SPGR and SSFP angles that provided greater __T__
