SST and rheumatoid arthritis: Radiopharmaceuticals for SPECT imaging, mainly using SST analogues radiolabelled with 111In or 99mTc, have been used in RA, however the appeal to PET/CT with 68Gallium (68Ga) conjugated octreotide/octreotate peptides (-TOC, -NOC, -TATE) could also be considered, in alternative to gamma-camera studies, since it provides high-quality images with a better resolution compared to SPECT.
