Predictive value of radionuclide joint scintigrams.
Twenty-two patients with normal or "noninflammatory" 99mtechnetium-labeled polyphosphate (TPP) peripheral joint scintigrams taken between 1974 and 1976 were reevaluated clinically. Retrospective chart review revealed that all initially had persistent polyarthralgia of more than 3 months duration. At followup, a mean of 3.6 years later, none had evidence of inflammatory joint disease, although 1 patient had systemic lupus erythematosus and 2 had polymyalgia rheumatica. A  noninflammatory joint scintigram as part of a thorough rheumatologic evaluation may be a useful procedure in excluding inflammatory joint disease in selected patients with chronic persistent polyarthralgia.
