The thyroid nodule: diagnostic strategy.

Abstract

This paper comments on the principal techniques (nuclear imaging echography and needle aspiration) and the most widely used protocols available for preoperative selection of thyroid nodule patients. Successively, the authors report the principles to define a new appropriate protocol based on needle aspiration and hormone assays and evaluate their experience with this new simple protocol. Long term clinical practices shows that surgical excision can be avoided for more than 90% of the nodule patients and that thyroid scintigraphy can be avoided for most of these patients, without appreciable disadvantage.
