Distributions of 13C6-Phe (a) and 13C6-Tyr (c) in mouse-xenograft lung tumor tissues (ntotal = 11) at 10, 30, and 60 min after tracer injection and at 10 min of control group (n = 3). Tracer-to-tracee (TTR) images for phenylalanine (a) and tyrosine (c) were calculated by normalizing the labeled amino acid signals to the intensities of their respective unlabeled versions. TTR values of Phe (b) and Tyr (d) were then differentiated annotated viable tumor and non-viable tumor regions for every time point
