Example demonstrating the quantification procedures for slice MRS and 3D-MRSI. ¹³C-lactate and ¹³C-alanine peak heights were important parameters in the final processed dynamic curves (left). The areas of hyperpolarized ¹³C resonances in the 3D-MRSI spectra were used in quantitative comparisons (right). The MRS example comes from data plotted in Fig. 3, and the 3D-MRSI example comes from a voxel from Fig. 5.
