The aim of our study was to determine if a fresh cadaver model is a viable method for teaching ultrasound (US)-guided breast biopsy of palpable breast lesions.
Third-year medical students were assessed both preinstruction and postinstruction on their ability to perform US-guided needle aspiration or biopsy of artificially created masses using a 10-item checklist.
Forty-one third-year medical students completed the cadaver laboratory as part of the surgery clerkship. Eight items on the checklist were found to be significantly different between pre-testing and post-testing. The mean preinstruction score was 2.4, whereas the mean postinstruction score was 7.10 (P < .001).
Fresh cadaver models have been widely used in medical education. However, there are few fresh cadaver models that provide instruction on procedures done in the outpatient setting. Our model was found to be an effective method for the instruction of US-guided breast biopsy among medical students.
我们研究的目的是确定新鲜尸体模型是否是一种可行的教学方法，用于教授超声（US）引导下对可触及乳腺病变进行乳腺活检。
使用一份包含10项内容的清单，对三年级医学生在指导前和指导后使用超声引导对人工制造的肿块进行针吸活检或穿刺活检的能力进行评估。
41名三年级医学生完成了尸体实验室课程，作为外科实习的一部分。清单上的8项内容在测试前和测试后有显著差异。指导前的平均分数为2.4分，而指导后的平均分数为7.10分（P <.001）。
新鲜尸体模型已在医学教育中广泛使用。然而，很少有新鲜尸体模型能提供门诊操作的教学。我们的模型被发现是一种在医学生中教授超声引导下乳腺活检的有效方法。
