title: Combined scintiscans in the diagnosis of thyroid carcinomas.
abstract: We correlated scintigraphy and histological findings in 40 cases of nodular goiter in which two or more kinds of scintigraphy were performed preoperatively. 201Tl scintigraphy for imaging thyroid carcinoma showed a diagnostic agreement of 80% for thyroid lesions and 82% for metastatic lesions in the cervical lymph nodes. These agreements were higher than with 99mTc-bleomycin scintigraphy. Thus, 201Tl scan can be used to evaluate 'cold' thyroid nodules and to visualize metastatic lesions. 201Tl scan was also found valuable as a diagnostic measure for local recurrence of thyroid carcinoma. However, there were a few false-positive and false-negative results.
