[Comments on the contribution of thyroid radionuclide imaging in the management of isolated thyroid nodules].

Now that new diagnostic methods have been developed, the role of conventional radionuclide scanning must be reevaluated. In fact, its performance for morphological analysis is not as good as that of ultrasonography. Correlation between the functional appearance of nodules and their regression with thyroid hormone therapy is not established. More importantly, as cold nodules are most often benign, the specificity of the method is not sufficient. Thallium radionuclide scanning is an interesting approach, but it is not widespread yet.
