  1. This table shows the chemical shift assignments of selected metabolites that have not been previously reported in particular types of brain tumour. The assignments are referenced to the methyl resonance of Cr at 3.03 ppm. Generally, assignments were made with reference to CPMG and/or TOCSY spectra of 15 samples representing 5 different types of tumour. Assignments in bold are taken from the literature assignments [19, 33].
