Top panel 68Ga-PSMA-11: PET, CT and PET/CT. Left cervical ganglion (arrow) maximum Standard Uptake Value (SUVmax) = 2.2. Lower panel 18F –DCFPyL: PET, CT and PET/CT. Left cervical ganglion (arrow) SUVmax = 2.6, Right cervical ganglion SUVmax = 2.3. Of note, 18F –DCFPyL shows new left supraclavicular metastases (arrow head). The color intensity has been slightly adjusted to highlight the uptake in the ganglia. There is higher and bilateral lower cervical ganglia uptake with 18F –DCFPyL. By CT, there is typically no anatomic structure detectable in the region of cervical ganglia; however, location, bilaterality and multiplicity would provide clues
