We report the case of a 74-year-old man with seropositive rheumatoid arthritis (RA) and
radiographic osteoarthritis (OA) who underwent dual-phase high-resolution 99m Tc-MDP
SPECT/CT. Early radiotracer enhancement was noted in 2 RA joints of the right hand, both
presenting with a ring-like uptake pattern around the joint, consistent with synovitis.
Insignificant early enhancement was noted at the first carpometacarpal joint, despite
presentation of CT features of OA. The delayed-phase enhancement patterns were distinct …
