Computed tomography findings in clinically normal and abnormal thyroid patients

Fifty normal volunteers had unenhanced thyroid computed tomography scans. A range of normal computed tomography densities and volumes was established for each age group. Pre- and postcontrast scans were done on 47 abnormal patients with hemorrhagic cysts, multinodular goiter, thyroiditis, papillary carcinoma, and benign adenomas. The computed tomography characteristics of each of the pathologic groups was noted for both the abnormal areas and the uninvolved part of the gland. Preliminary observations of the computed tomography characteristics of each abnormality are discussed.
