摘要：

A modified spin-echo pulse sequence is described that enables accurate T-2 measurements to be made in NMR microimaging experiments. The modified sequence eliminates cumulative diffusion losses that lead to an underestimation of the T-2 relaxation time using conventional spin-echo pulse sequences. The approach is theoretically justified and confirmed in comparative experiments on phantoms. (C) 1995 Academic Press, Inc.
