Abstract:
Objective To retrospectively investigate the value of contrast enhanced ultrasound ( CEUS) in breast cancer biopsy . Methods A total of 49 consecutive patients with biopsy confirmed breast cancer were retrospectively analyzed . All patients underwent CEUS and biopsies were thus performed targeting both the high perfusion and low/non‐perfusion regions on CEUS . T he diagnostic performance and core cancer involvement of the biopsy cores taken from the high perfusion regions were compared with those from the low/non‐perfusion . Results A total of 53 breast cancer lesions were biopsy confirmed in 49 patients .CEUS revealed homogeneous enhancement in 8 lesions ( 15 .1% ) ,and heterogeneous enhancement in 45 lesions ( 84 .9% ) . T he diagnostic accuracy rate for biopsy cores taken from the high perfusion regions was significantly higher than that from the low/non‐perfusion regions ( 98 .5% vs 72 .9% , P ＜0 .01) . T he core cancer involvement was also higher in high perfusion lesions ( 55% vs 30% , P ＜0 .01) . Conclusions CEUS can differentiate the active area and necrotic fibrosis area of breast tumors by displaying the microvessels ,thus contributing to the selection of biopsy sites .
