| Abstract: | Thyroid scanning was performed in 135 hyperthyroid cats and 13 normal cats with technetium-99m as pertechnetate (99mTcO4) or with radioactive iodine (131I). Of the hyperthyroid cats, enlargement and increased radionuclide accumulation were found in one thyroid lobe in 38 (27%) and in both lobes in 97 (73%). In two hyperthyroid cats with thyroid carcinoma, extension of tumor into the thoracic cavity was detected. In normal and hyperthyroid cats the radionuclide images produced with 99mTcO4 and 131I were similar; however, the quality of the 99mTcO4 scans was usually better than that of the 131I scans. |
