RESUMEN
OBJECTIVE: To investigate the enhancement pattern of thyroid carcinoma with contrast-enhanced ultrasound (CEUS) for the diagnostic value. METHODS: Thirty-one cases with thirty-five thyroid Occupied were retrospectively reviewed. The final diagnosis was confirmed by biopsy pathology. Contrast agent SonoVue and contrast pulse sequencing (CPS) technique were used in this study. RESULTS: Thirty-five thyroid carcinoma presented three enhancement patterns with CEUS. Type I: twenty-three lesions enhanced in a pattern of ring with centripetal fill-in, however, the central part of no contrast agent filling. Type II: five lesions enhanced regularly and homogeneously. Type III: seven lesions enhanced irregularly and homogeneously. Thyroid benign and malignant lesions perfusion time curve, compared to papillary thyroid carcinoma with nodular goiter in the AT, TTP and WT indicators P < 0.05; papillary thyroid carcinoma and thyroid adenoma, compared to WT alone an indicator of P < 0.05. CONCLUSIONS: Identification of the different enhancement patterns of thyroid carcinoma could improve the diagnostic ability of CEUS.
