Top panel 68Ga-PSMA-11: axial PET, axial CT and axial fused PET/CT. Lower panel 18F –DCFPyL: axial PET, axial CT and axial fused PET/CT. The color intensity has been slightly adjusted to highlight the uptake in the ganglia. Right upper lumbar ganglion (arrows) uptake with 18F –DCFPyL (SUVmax=2.4) > with 68Ga-PSMA-11 (SUVmax=2.3). By CT, similar to cervical ganglia, there are typically no anatomic structures detectable in the region of lumbar ganglia; however, paravertebral location, bilaterality and multiplicity would provide clues
