Thyroid scanning with gallium-67 and cesium-131
Abstract:
The roles of 131Cs and 67Ga in the evaluation of solitary thyroid nodules were investigated. Radionuclide scans were performed with 67Ga and 131I in 27 patients and with 131Cs and 131I in 43 patients. Gallium-67 detected only two of eight malignant nonfunctioning nodules and 131Cs detected one of three such nodules. The contribution of 131Cs and 67Ga to the preoperative identification of malignant thyroid lesions is of doubtful value.
