Abstract: Objective To investigate the enhancement patterns of hypervascularized breast tumors with real time contrast-enhanced ultrasound (CEUS) and to evaluate the accuracy of CEUS in comparison with power Doppler in the discrimination purpose. Methods CEUS was preoperatively performed in 35 patients with 37 hypervascular breast lesions detected on power Doppler. The patterns of enhancement were analyzed and compared with morphological characteristics of the vessels displayed by power Doppler. Results Considering initial lump enhancement and peripheral flake enhancement as a criterion suggesting malignancy, CEUS showed a sensitivity of 90.9% ,a specificity of 73.3% and an accuracy of 75.70/00. While the morphological characteristics of the vessels demonstrated by power Doppler showed no significant difference between benign and malignant lesions, Conclusions CEUS is more accurate than power Doppler ultrasound in the assessment of blood flow of hypervascular breast tumors and more helpful in the differentiation role.
