Impact of breast biopsy markers on magnetic resonance-guided focused ultrasound

The presence of biopsy markers introduces marker-dependent complexities into magnetic resonance-guided focused ultrasound treatment planning and monitoring. Reliable monitoring and energy delivery are achievable when the target is sufficiently far from the marker but become unreliable when the target is close to the marker. Accordingly, the potential impacts of biopsy markers on the safety and efficacy of MR-guided focused ultrasound treatments should be considered carefully.
