title: Application of special diagnostic techniques in the management of nodular goitre.
abstract: The primary challenge in the management of nodular goitre is to establish which thyroid nodules are malignant. Since selection of patients for operation on the basis of palpation of nodules alone gives a low yield of malignant disease, physicians have sought criteria for selection that combine the information obtained from special laboratory procedures with thoughtful clinical appraisal. Such special procedures, which include radioisotope scintiscanning, echography by B-mode ultrasonography, and either large- or fine-needle aspiration and cytologic examination of the aspirate, are considered valuable in a proposed clinical approach to the management of thyroid nodules.
