Phasing spin-echo-acquired 31P spectroscopic images using complex conjugate data reversal.

A simple method has been developed for phasing 31P spectroscopic images acquired with short echo-time (1-2 ms) spin-echo sequences. The technique is based on reconstructing complete echoes in the time domain by the reversal of the complex conjugate of the data. After Fourier analysis, a magnitude reconstruction is used, which no longer broadens the lines. Advantages of the method compared to other phasing procedures are discussed.
