Application Value of High Frequency Ultrasonography in Nonpalpable Breast Lesions

Objective To evaluate the application value of high frequency ultrasonography in diagnosis and treatment of nonpalpable breast lesions.Methods The high-frequency ultrasonographical examination results of 102 patients with nonpalpable breast lesions(138 lesions) were analyzed retrospectively,and puncture biopsy was performed guided by ultrasound locatization.Results A total of 126 benign lesions and 12 malignant were found.The ultrasonography imaging characteristics of benign breast lesions were as follows:regular morphology,clear border,even echo without internal microcalcifications or rear attenuation.The benign lesions were excised completely guided by ultrasonography.Microcalcifications were seen in 7 malignant lesions,rear attenuation in 10 malignant lesions.Breast lesions with microcalcifications and rear attenuation indicated malignance.Breast-conserving surgeries were done.Conclusion The imaging features of nonpalpable breast lesions can be observed with high-frequecy ultrasonography.It plays an important role not only in early diagnosis and treatment but also in localization and guidance of puncture biopsy and lesion excision.
