The purpose of this study was to implement a short echo MRSI acquisition at 7 Tesla. Data from phantom, healthy volunteers and patients with gliomas were acquired. The 2D H-1 MRSI was localized using spin echo with TE/TR = 30/2000 ms and spectral array = 20x20. MRSI data of good quality were demonstrated, and this method may be applied in a larger study of patients with gliomas to assess whether it provides additional information compared to the conventional MRSI acquisitions at 3T and 7T.
