Are breast biopsy markers underused?

Introduction To evaluate current use of breast biopsy markers (BBM) amongst Australian and New Zealand radiologists. Methods Radiologists attending a national breast conference were invited to complete an online survey addressing demographics, BBM use following ultrasound, stereotactic, tomosynthesis and MRI-guided biopsy, frequency of early BBM displacement, preoperative lesion localisation (PLL) and axillary BBM use. Results Overall response rate was 52% (60/115). The majority (n = 45) 75% practiced in Australia. 98% had BBMs available in their practice, 40% reported BBM costs weren't covered by insurance. 27% would use BBMs more often if they were, with some utilising smaller gauge devices for lesion sampling to minimise need for BBM use and patient out-of-pocket costs. Ultrasound-guided procedures were associated with lower rates of clinically significant BBM displacement (P = 0.001). Considering PLL, 44% were able to perform US-guided PLL in
