A novel technique for teaching challenging ultrasound-guided breast procedures to radiology residents

Ultrasound-guided breast interventions (core biopsies, needle-wire localizations, and fine-needle cyst aspirations) are common procedures performed by radiologists. Residents must gain competency in these interventions during training. Phantoms and simulations have been advocated for teaching interventions, and various systems are available for standard breast interventions. However, simulations for difficult/high-risk interventions are not readily available. We describe an inexpensive method for simulating difficult ultrasound-guided breast procedures, including masses over breast implants, deep masses along the chest wall, and lymph nodes adjacent to axillary vessels.
