Fig. 1From: Non-invasive detection of 2-hydroxyglutarate in IDH-mutated gliomas using two-dimensional localized correlation spectroscopy (2D L-COSY) at 7 Tesla7T COSY spectrum from an 11.0 ml voxel localized within a patient with mutant-IDH1 WHO grade III anaplastic astrocytoma (middle inset). Metabolite peaks including the resonance peak due to 2HG have been labeled. The cross peaks from 2HG at [F2, F1] = 4.0, 1.7 ppm are identified within the red box Back to article page
