Demonstration of nodules in the normal thyroid by echography

Abstract

Half-yearly bone scintigrams of 27 patients with Paget's disease, who were treated with the bisphosphonate APD, were evaluated. Uptake of ⁹⁹Tc^m-Sn-EHDP was determined by computer analysis. All patients reached clinical and biochemical remission, usually within 6 months. The scintigraphic uptake dropped steeply during the first 6 months and only slightly during the second 6 months. The decrease in uptake was proportional to the original uptake and averaged 80% of this value. The residual 20% persisted, although clinical and biochemical remission were attained. The scintigraphic results obtained with APD agree with our earlier findings for patients in remission after treatment with a combination of calcitonin and EHDP.
