Abstract:
ObjectiveTo investigate the value of CEUS in differential diagnosis of benign and malignant thyroid solid lesions.MethodsTotally 45 patients with thyroid solid lesions underwent CEUS examination.The enhancement mode and blood perfusion characteristics of malignant and benign lesions were analyzed,and the results were compared with pathology.ResultsCEUS diagnosed 31 benign lesions and 14 malignant masses.The diagnostic accordance rate of CEUS was 93.75％ (30/32) and 92.31％ (12/13) for benign and malignant lesions respectively.In 31 benign lesions,27 (27/31,87.10 ％) showed entire homogeneous enhancement,4 (4/31,12.90％) presented inhomogeneous enhancement.In 14 malignant masses,1 (1/14,7.14 ％) showed homogeneous hypoechoic enhancement,12 (12/14,85.71％) presented inhomogeneous hyperechoic enhancement and 1 (1/14,7.14％) presented non-enhancement.ConclusionCombined with two-dimensional grey scale ultrasound and CDFI,CEUS enables dynamic observation of the microvascular perfusion of thyroid lesions,therefore helps to differentiate benign and malignant thyroid lesions.
