LOW COST PHANTOM FOR TEACHING US-GUIDED BREAST BIOPSIES

Objectives: Due to the spread of mammographic screening, a lot of impalpable lesions are detected and a greater number of biopsies guided are demanded. Ultrasound biopsy guided requires skill to optimize the representation of the lesion to be investigated. In residency programs is necessary to the proper training of these procedures. Ensuring that students obtain the skills necessary to safely and accurately perform US-guided breast biopsy is a challenge. Commercial phantoms have several problems and are expensive. It was necessary to develop a simulator to allow the initial teaching of techniques needed to achieve this goal. The authors present a low cost phantom for teaching US-guided biopsies. Methodology: We developed a phantom for teaching and training needle biopsy using a chicken breast, which has ultrasound attenuation characteristics similar to the human breast. Stuffed olive and a piece of glove with water were used to mimic a solid lump and a cyst. These artifacts were introduced carefully into the phantom described. Results: The phantom was effective, low-cost and assisted in the technical education in addition to reducing the anxiety of professionals who have undergone the training. Conclusion: The authors conclude that this tool is useful, inexpensive and easily reproducible, helping in the teaching of breast biopsy.
