The effect of non-uniform tilt angles across the slice thickness on the determination of T1 in NMR imaging is investigated in saturation-recovery, spin-echo and inversion-recovery pulse sequences. It is shown that for each of these imaging protocols, non-uniform tilt angles imply a multi-exponential dependence of NMR signal on the pulse repetition interval TR.
