    Abstract

    Scanning of the thyroid gland after the administration of radioactive caesium (131Cs) was performed in 45 patients; in 38 of these it had been shown that a thyroid nodule failed to accumulate sodium per-technetate (99mTc) or sodum iodide (131I). 131Cs was concentrated in the nodule to a greater degree than in the paranodular thyroid tissue in seven patients, in five of whom thyroid carcinoma was subsequently identified. In five patients 131Cs accumulated in both the nodule and paranodular tissue, while in the other 26 no 131Cs uptake occurred in the nodule. In only one of the latter group was the thyroid lesion malignant. Caesium scanning seems to offer a useful supplementary procedure in the investigation of thyroid nodules.
