Fast proton spectroscopic imaging of human brain using multiple spin-echoes
Authors:Jeff H. Duyn  Chrit T. W. Moonen
Abstract:
We introduce a multi-echo multi-slice MR proton spectroscopic imaging method, which allows for a dramatic reduction of the measurement time by acquiring multiple spin-echoes within a single repetition time. In the multi-echo multi-slice experiment discussed in this paper, a threefold reduction in measurement time is obtained by sacrificing some spectral resolution. Signal-to-noise ratio and spatial resolution are preserved. Metabolite images of N-acetyl aspartate, and total choline + total creatine from multiple slices through the human brain are presented and compared with images obtained with a conventional single-echo multi-slice method.
Keywords:proton spectroscopic imaging  brain, MIR  fast MR imaging
