Fast proton spectroscopic imaging of human brain using multiple spin‐echoes

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.
