RESUMO
Objective Breast intraductal papillary lesion ( BIPL) has a low incidence but a high rate of malignancy .This study discusses the diagnostic value of conventional ultrasonography ( US) combined with ultrasonic elastography ( UE) for breast papil-lary lesion. Methods We analyzed the preoperative ultrasound data of 48 patients with 63 BIPLs, and classified them according to the characteristics of two-dimensional ultrasound (2DUS) images.Then we compared their color Doppler ultrasound characteristics and UE features with the pathological results . Results Based on the 2DUS findings, the BIPLs were divided into 4 types.The sensitivi-ty, specificity, and accuracy of conventional US +UE in the diagnosis of BIPL were 93.2%, 88.9%, and 90.5%, respectively, markedly higher than those of conventional US (75.6%, 66.7%, and 73.0%), with statistically significant differences in the areas under the curve between the two methods (0.918 vs 0.838, P<0.05). Conclusion Conventional US combined with UE can im-prove the diagnosis of breast intraductal papillary lesion .
