Fig. 1From: Central delivery of iodine-125–labeled cetuximab, etanercept and anakinra after perispinal injection in rats: possible implications for treating Alzheimer’s diseaseIn vivo distribution of iodine-125 (I-125)–labeled cetuximab after perispinal injection using single-photon emission computed tomography (SPECT). a Biodistribution of I-125–labeled cetuximab suggested the injection to be intrathecal instead of perispinal. b The biodistribution displayed is in line with images of the other four animals that received perispinal injections. The radiolabeled drug in these animals was found only at the injection siteBack to article page
