To the Editor.—We read with interest the article by Drs Hammer, Wortsman, and Folse (Archives 1982;117: 1020-1023). We think they have made valid observations and we appreciate the publication of this series of correlating studies in thyroid lesions. Several points are raised, however, regarding the sonographic studies reported.
