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 (arrows). Left stellate ganglion with 18F –DCFPyL (SUVmax = 2.5) > 68Ga-PSMA-11 (SUVmax = 2.1). Metabolic activity is more commonly noted in the left side. By CT, stellate ganglia are typically located anterior to first rib and have curvilinear or nodular shape
