Clinical application of computed tomography to thyroid disease

CT examinations were carried out in 62 patients with various thyroid disorders, 42 patients with thyroid nodules, 12 with diffuse abnormality and 8 of others. Evaluation was made whether CT could provide more information compared with other techniques. Cystic thyroid nodules could be differentiated from solid nodules with a reasonably high degree of accuracy. Uncalcified thyroid carcinoma was noticed as an ill-defined nodule with irregular wall, grossly the same in density with the muscle in plain CT, and not opacified by contrast material. CT has the ability to define the nature of the thyroid nodules better than other nontraumatic diagnostic modalities.
