Correlation analysis of different calcified thyroid nodules with age and gender by contrast-enhanced ultrasound / 中华超声影像学杂志

ABSTRACT

Objective To investigate the value of contrast-enhanced ultrasound(CEUS) to diagnose thyroid nodules with different calcifications,and analyze its correlation with age and gender.Methods The image characteristics of high frequency ultrasound and pathological results of 522 patients with calcified thyroid nodules were analyzed retrospectively.CEUS enhancement patterns of different age and gender were observed and compared.Results There were no malignant nodules in patients under the age of 10.In the group of male and female,malignant nodules patients constituted the highest proportion between 40-49years old and a minimal proportion between 10-19 years old.The CEUS for weak enhancement with micro calcifications were mostly malignant nodules;the high or equal enhancement with macrocalcifications were mostly benign nodules.But a part of micro calcifications in young women patients (20 to 29 years old) with high or equal enhancement were mostly malignant nodules.Conclusions The CEUS for weak enhancement with microcalcifications are mostly malignant nodules,but a part of microcalcifications in young women patients (20 to 29 years old) with high or equal enhancement are mostly malignant nodules.
