PET imaging of [¹⁸F]5. a Representative maximum intensity projection PET images of BALB/c mice following injection of 1.48 MBq of [¹⁸F]5 via tail vein. Time frames were summed into images representing 0–1, 1–5, 5–15, 15–30, 30–45 and 45–60 min post radioactive injection. Coronal (top) and sagittal (bottom) projections are shown. b Time activity curve of [¹⁸F]5 in bladder, liver, lung, brain and whole body over 60 min post i.v. injection of 1.48 MBq of [¹⁸F]5 via tail vein, expressed as % of injected dose normalised to body weight (%ID/g). c Same as b but in gallbladder and intestine. Data are mean + SEM, n = 4
