ABSTRACT
Objective To investigate radionuclide imaging pattern with ~ 99m Tc-MDP in rat arthritis induced by collagen, and the significance of the imaging in the early diagnosis of arthritis. Methods 70 male Wistar rats were divided into normal (n=28) and model group (n=42), both groups were respectively subdivided into 7 groups according to time of treatment. Collagen induced arthritis (CIA) model was reproduced by subcutaneous injection of collagen and adjuvant. For imaging, rats were injected with ~ 99m Tc-MDP through tail vein. The technique of Radome of Interesting (ROI) was used in knee and whole bone, and R value was calculated. The concentration of radionuclide was observed and compared with arthritis index (AI), paw thickness, pathological changes and ?-ray examination. Results Rats in model group showed higher concentration of radionuclide in the knee joint (P
