ABSTRACT:
A multiecho NMR pulse sequence is modified such that the bandwidth of the encoded NMR echo signal is reduced for the second NMR echo signal. This reduction is achieved by reducing the magnitude of the read-out magnetic field gradient, increasing the duration of the acquisition by a proportional amount and decreasing the sample rate by a proportional amount for the second NMR echo signal.
