[Value of thallium scintigraphy in thyroid pathology].

The value of thallium 201 (Tl 201) scintigraphy was investigated in 45 patients with thyroid affections. Scintigrams were performed with both technetium 99 m (Tc 99 m) and Tl 201. Of the 27 patients with 43 thyroid nodules confirmed histologically (16 patients were operated upon and needle puncture cytology conducted in 11 cases), all cold nodules to Tc 99 m and Tl 201 were found to be benign.
