To determine the imaging characteristic of frequent target lesions of wireless ultrasound US-guided, vacuum-assisted breast biopsy Wi-UVAB and to evaluate diagnostic yield, accuracy and complication of the device in indeterminate breast lesions.

Materials and Methods

From March 2013 to October 2014, 114 women age range, 29–76 years; mean age, 50.0 years underwent Wi-UVAB using a 13-gauge needle Mammotome Elite®; Devicor Medical Products, Cincinnati, OH, USA. In 103 lesions of 96 women with surgical n = 81 or follow-up n = 22 data, complications, biopsy procedure, imaging findings of biopsy targets and histologic results were reviewed.


Mean number of biopsy cores was 10 range 4–25. Nine patients developed moderate bleeding. All lesions were suspicious on US, and included non-mass lesions 67.0% and mass lesions 33.0%. Visible calcifications on US were evident in 57.3% of the target lesions. Most of the lesions 93.2% were nonpalpable. Sixty-six 64.1% were malignant ductal carcinoma in situ DCIS rate, 61% and 12 were high-risk lesions 11.7%. Histologic underestimation was identified in 11 of 40 27.5%. DCIS cases and in 3 of 9 33.3% high-risk lesions necessitating surgery. There was no false-negative case.


Wi-UVAB is very handy and advantageous for US-unapparent non-mass lesions to diagnose DCIS, especially for calcification cases. Histologic underestimation is unavoidable; still, Wi-UVAB is safe and accurate to diagnose a malignancy.
