Fig. 1: Biodistribution of 68Ga-grazytracer in human.

a Representative PET images of 68Ga-grazytracer at 5, 10, 20, 40, and 90 min post-injection. b, c Quantified mean standard uptake value (SUVmean) of 68Ga-grazytracer in healthy tissues at 5, 10, 20, 40, and 90 min post-injection (n = 4, collected from 4 different patients). The curves were fitted and depicted using a quadratic (second-degree polynomial) model. Data points represent the median SUVmean values, with error bars representing the interquartile range.
