|
Background and Objectives: To examine the prevalence of thyroid nodules and cancers in Korea and to evaluate the role of the radiologists in sonography of the thyroid nodule.
Materials and Methods: 6351 persons, who underwent the thyroid sonographic examination at 10 university and general hospitals in 2004, were included. The number and size of thyroid nodules and pathologic results of fine needle aspiration cytology (FNAC) and operation were retrospectively evaluated.
Results: Incidence of thyroid nodules was 75.4 (4787/6351)% and that of the thyroid cancer was 8.3 (531/6351)%. Thyroid nodules were detected in 1,532 (59.0%) and thyroid cancer was confirmed in 3% (male 2.1%, female 3.4%) by screening examination in medical health center. Outpatients with thyroid nodules were 3,255 (86.2%) and the incidence of thyroid cancers was 11.8% (male 14.6, female 11.3%).
Conclusion: The prevalence of thyroid nodules detected on sonography was 75.4% and there is no significant difference between male and female. The incidence of thyroid cancer in male and female was also similar at the medial health center and out-patient center. Radiologists played an important role in evaluating thyroid nodules and performing FNAC to detect the thyroid cancer.
