Thyroidnodule scanning by using ultrasonography during health check-up / 中华健康管理学杂志

ABSTRACT

Objective To study the effectiveness of ultrasonography in thyroidnodule disease detection and malignant/benign lesion differentiation during health check-up.Method Thyroid examination data of Peking Union Medical College Hospital(PUMCH)staff over the last 6 years were retrospectively reviewed.The results of thyroidnodule scanning by using ultrasonography were compared with the findings of physical examinations.Results Among 6348 health check-up receivers from 2006 to 2010,450 were found to have thyroidnodule(detection rate 7.09％).Twenty malignant lesions were confirmed in histological examinations(mean detection rate per year 0.38％).In 2011,1706 thyroid glands were scanned by both physical examination and ultrasonography,and 525 thyroidnodules were identified(detection rate 30.77％).Surgical operations were performed for 22 suspected malignant tumors,and 18 malignant lesions were finally confirmed(detection rate 1.06％).Conclusion Ultrasonography can improve the detection of thyroidnodule.Irregular shape,microcalcification,and rich blood-flow may indicate malignant nodules.
