Analysis and assessment of real-time contrast-enhanced ultrasonography in the diagnosis of breast masses

Objective To investigate the perfusion characteristics of intraductal breast lesion by real-time gray-scale contrast ultrasound and to determine the value of real contrast ultrasound in the diagnosis of breast masses. Methods A total of 30 breast lumps by ultrasound contrast enhancement were observed from the enhanced level. An enhanced mode and enhanced border were observed when the lesion was clear. The perfusion characteristics were compared between the benign and malignant lesions. Results Thirty breast lumps include 17 benign lumps and 13 benign lumps by pathological operation.After injected with the microbubble contrast medium,all breast lumps enhanced to varied extent. And malignant lesions showed significant enhancement for more than 3 grade(69.2%,9/13).The radial enhancement around lesion were mainly observed in the malignant lesions (P0.05). Conclusion The microvascular perfusion of breast intraductal lesions can be clearly displayed by real-time gray-scale contrast-enhanced ultrasound. The feasibility of differentiation between benign and malignant lesions according to their perfusion characteristics appears to be promising.
