Comparison of Tc-99m HIG and Three-Phase Tc-99m MDP Bone Scintigraphy for Evaluating the Efficacy of Yttrium-90 Silicate Radionuclide Synovectomy

Abstract

Based on these findings, Tc-99m HIG scintigraphy appears to be a valuable method that complements clinical assessment of the efficacy of Y-90 silicate therapy in rheumatoid knee synovitis, starting in the early post-treatment period. However, three-phase Tc-99m MDP bone scintigraphy may be valuable in the late postsynovectomy period.
