Ultrasonography is noninvasive and inexpensive, and represents the most sensitive procedure for identifying thyroid lesions and for determining the diameters of a nodule (2-3 mm). Chest radiography, CT, and MRI are not usually used in the initial workup of a thyroid nodule, except in patients with clear metastatic disease at presentation. These tests are second-level diagnostic tools and are useful in preoperative patient assessment.
