↵* Activity in the right submandibular gland was measured at only the first postinjection time point, whereas activity in the other tissues was measured at both time points.
For malignant lesions, spleen, and intestine (other), SUV_max is median and P was obtained with Mann–Whitney U test; for submandibular gland, liver, and duodenum, SUV_max is mean and P was obtained with t test.
