Diagnosis of thyroid microcarcinoma using contrast-enhanced ultrasound / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the diagnostic value of thyroid microcarcinoma using contrastenhanced ultrasound(CEUS).Methods The CEUS characteristics of 31 lesions in patients with thyroid microcarcinoma which were confirmed by surgery and pathology were retrospectively analyzed.[Results]The enhancement features of 31 lesions were hypoenhancement,morphological irregularity,and lack of a complete envelope.The time intensity curve showed late washed in and late washed out.The start-time of the lesions was later than that of normal thyroid tissue.The enhancement intensities of the lesions were lower than that of normal thyroid tissue.Conclusions The contrast enhancement patternshypoenhancement,suggested that the CEUS might provide a useful,quantitative analysis method for the diagnosis of thyroid microcarcinoma,which can improve diagnostic confidence in thyroid microcarcinoma.
