[Contact radiotherapy in rheumatoid lesions of the knee joint using Au-198]

An instrumental-calculation method of assessment of an absorbed dose of radiation in the synovial tissue of the knee joint in radionuclide therapy with 198Au using directly measured topometric parameters was used for patients with rheumatoid arthritis. A group of 294 knee joint of 138 patients was considered by way of a retrospective analysis. Dosimetric indices in all cases (except stage IV arthritis) showed values which were not contrary to clinical assessment of the patients: status after therapy.
