Fig. 8From: Simultaneous PET/MRI with 13C magnetic resonance spectroscopic imaging (hyperPET): phantom-based evaluation of PET quantificationExamples of 13C spectroscopy during PET gantry ON and OFF. Plots show 13C spectra under conditions of the PET gantry ON and OFF, as denoted in the legend. Spectra are from the voxel with the maximum urea signal and zoomed on the urea peak to highlight the small differences of the spectraBack to article page
