Clinical application of /sup 201/Tl scintigraphy in patients with cold thyroid nodules

Journal Article · · Clin. Nucl. Med.; (United States)
/sup 201/Tl-chloride scintigraphy was performed in 45 patients with cold thyroid nodules. The /sup 201/Tl scintigram was positive in 17 of 18 thyroid patients with cancer (94.4%), 8 of 20 patients with an adenoma (40.0%), 1 of 2 adenomatous goiter patients (50.5%), and all of 5 cases of chronic thyroiditis (100.0%). When the cold nodule was demonstrated to be positive with /sup 201/Tl, the statistical chance of the lesion being a cellular one was 100.0% and a risk of its malignancy was 54.8%. On the other hand, the nodule with negative /sup 201/Tl concentration had a 14.3% chance of cellularity and a 7.1% risk of malignancy. Thus, /sup 201/Tl scintigraphy is of use in the differential diagnosis of the cold thyroid nodule.
