We report a case of a 73-y-old man with a history of metastatic colon cancer who underwent a PET/CT scan for restaging. In the PET scan, there was intense and diffuse distribution of 18F-FDG in his left forearm and hand. This is a classic sign of an accidental intraarterial injection of 18F-FDG in the antecubital region. Similar phenomena after inadvertent intraarterial injection of other radiotracers are reviewed. The associated risk factors, preventive measures, and radiation dose to the arm are discussed.}, issn = {0091-4916}, URL = {https://tech.snmjournals.org/content/39/4/249}, eprint = {https://tech.snmjournals.org/content/39/4/249.full.pdf}, journal = {Journal of Nuclear Medicine Technology} }
