ABSTRACT
PURPOSE: To improve the ability of technicians and physicians to find and diagnose breast lesions in breast ultrasound screening. METHODS: Seminars were organized for technicians and physicians engaged in breast ultrasound screening, and tests were carried out to evaluate the usefulness of the seminars. Each seminar lasted 2 days and comprised lectures and group activities. Pretests and post-tests conducted before and after each seminar, respectively, consisted of 100 questions: 50 about animated images, and 50 about static images. The tests required the participant to find lesions in animated images and estimate the probability of malignancy from static images. RESULTS: In the animated image tests, sensitivity was greater after the seminar, although specificity did not change significantly. In the static image tests, sensitivity increased, and a significant increase was also observed in the receiver operating curve analysis for degree of certainty in diagnosing cancer. CONCLUSION: The seminars improved the participants' ability to find and diagnose breast lesions during ultrasound screening.
