Further characterization of iodide-induced hyperthyroidism based on the direct measurement of intrathyroidal iodine stores84

Clinical, scintigraphic and laboratory findings in a group of 23 hyperthyroid patients with inappropriate total intrathyroidal iodine pool (ITI), measured by X-ray fluorescence, were compared to those of 25 hyperthyroid patients with low ITI. Differences are discussed which may be useful in the diagnosis of this clinical entity</p

Usefulness of 99mTechnetium pertechnetate in periarteritis nodosa.

Radioisotopes have a wide range of application in the clinical investigation of many organs. Muscle diseases are an exception in this expanding field. We report here a case of periateritis nodosa in which unusual scintigraphic images were obtained with 99mTc-pertechnetate. The kinetics of this isotope and the scintigraphic changes were followed during treatment and found to be useful clinical tools
