ABSTRACT:
A fast spin-echo NMR pulse sequence is modified to produce a pair of gradient recalled echo signals between each successive pair of RF refocusing pulses. The first gradient recalled echo signal in each pair is acquired and employed to reconstruct a first image and the second gradient recalled echo signal in each pair is employed to reconstruct a second image. The two gradient recalled echo signals in each pair are separately phase encoded such that the two reconstructed images having contrasting T.sub.2 -weighting.
