Title: The value of contrast enhanced ultrasound in breast cancer biopsy
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. The 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%). The 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). The 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.
