The purpose of this study is to evaluate benign and/or malignant thyroid tumors with /sup 201/T1 thyroid scan. We studied 76 cases of histologically verified thyroid tumors, all seen as cold nodules on the /sup 123/I thyroid scan. /sup 201/T1 thyroid scan was performed 5-15 minutes (early scan) and 3-5 hours (delayed scan) after intravenous administration of 1.5-2.0 mCi of /sup 201/T1. In 35 (94.6%) of 37 malignant tumors (anaplastic carcinoma, six; papillary carcinoma, 23; follicullar carcinoma, five; epidermoid carcinoma, one;malignant lymphoma, 1), /sup 201/T1 accumulated in the cold nodule of the /sup 123/I thyroid scan on both early and delayed scans. On the other hand, the delayed /sup 201/T1 scans, we were able to differentiate most malignant thyroid tumors from those which were benign. False-negative and -positive cases are discussed.
