(A) Biodistribution at 120 minutes (crush model; 68Ga-FBP14, n = 5; 111In-FBP15, n = 8; 99mTc-FBP16, n = 6). (B) Representative autoradiographs of excised injured and contralateral carotid arteries after injection of 111In-FBP15, and ipsilateral:contralateral ratios for each probe (n = 5 – 6 per probe). (C) Pharmacokinetic data from ex vivo blood analyses (68Ga-FBP14, n = 5; 111In-FBP15, n = 8; 99mTc-FBP16, n = 4; ○ total radioactivity in plasma; ● functional probe). *P <0.05. ***P <0.001.
