Abstract:
Objective To evaluate the value of real time three-dimensional ultrasound in differentiating benign and malignant breast tumors. Methods One hundred and fifty-three patients with breast tumors were examined with real time three-dimensional ultrasound. The results were compared with post-operative pathological results. Results A sign of malignancy on the coronal plane was observed by three-dimensional ultrasonography,named “sun-like symptom”,because the sign looked like a shining sun:striated hyperechoic or iso-echoic images scattered radially around cancers,together with the distortion of normal tissue.The accuracy of the sign in differentiating benign and malignant breast tumors was 86.93 %( 133/153 ), the sensitivity was 78.38 %( 58/74 ), and the specificity was 94.94 %( 75/79 ). Conclusions Real time three-dimensional ultrasound is a valuable and new technique in differentiating benign and malignant breast tumors.
