RATIONALE AND OBJECTIVES: Use of a turkey-breast phantom for developing freehand ultrasound (US)-guided core-needle biopsy skills was evaluated. MATERIALS AND METHODS: Thirteen diagnostic radiology trainees with varied experience in freehand US-guided breast core-needle biopsy were given instruction and allowed to practice the technique in a turkey-breast phantom. Three attempts were made before and after instruction and practice, and a questionnaire regarding experience, confidence, and anxiety was administered after these attempts. Technique, accuracy, and completion time were evaluated. RESULTS: Confidence related to procedure performance increased (P < .01), but the change in anxiety was not statistically significant. Accuracy improved, with the target being obtained in 87% of passes performed after instruction and practice versus 56% initially. Difficulty with visualizing the core needle sonographically during phantom biopsy decreased from 49% to 5% of attempts. Needle positioning perpendicular to the chest wall was observed initially in 38% of passes but was not observed after instruction and practice. There was no statistically significant change in time to complete biopsy. CONCLUSION: For teaching US-guided breast core-needle biopsy, use of a turkey-breast phantom helps improve technique, accuracy, and confidence of diagnostic radiology trainees.
