Abstract

Abstract: The purpose of this study was to explore the value of mammography and contrast-enhanced ultrasonography in the diagnosis of breast non-mass-like lesions (NMLE). A total of 110 cases of NMLE were selected for mammography and contrast-enhanced ultrasonography, and were compared with pathological results. The results show that 87 cases of malignant lesions and 23 cases of benign lesions were confirmed by pathology. The mammography of malignant lesions showed the proportion of calcification, asymmetry or disorder, irregular high density were significantly higher than that in benign lesions (P<0.05). There was significant difference in the contrast-enhanced manifestations of malignant and benign lesions (P<0.05). The sensitivity, accuracy and negative predictive value of contrast-enhanced ultrasound in the diagnosis of benign and malignant lesions were significantly higher than those of mammography (P<0.05). The results showed that compare with mammography, contrast-enhanced ultrasonography has a higher value in differentiating benign and malignant lesions of NMLE, which is worth clinical use.

Key words: mammography, contrast-enhanced ultrasonography, non mass enhanced lesions of breast, diagnostic value
