| Abstract: | This report describes the use of 99mtechnetium pertechnetate (99mTcO4?) and 131for imaging of a metastatic thyroid carcinoma in a dog. The 131] imaging showed metastatic lesions undetected by the 99mTcO4? imaging on 2 separate occasions. The possible mechanisms for the discrepancies between 131I and 99mTcO4? imaging of thyroid carcinomas are discussed. The use of 131I for the imaging of functional thyroid carcinomas in the dog is recommended. |
