To improve the quality of breast cancer screening by ultrasonography, both effective training and evaluation of the performance of the examiners of breast ultrasound are essential.
The Educational Committee of the Japan Association of Breast and Thyroid Sonology, an NPO, has established 2-day training programs on breast ultrasonography with tests at the end of the programs. The tests are performed using images to evaluate the ability of observers to detect and evaluate lesions on ultrasound. Ability to detect lesions was examined by using videos, and ability to evaluate lesions was examined by using still images. The results of tests taken by 422 physicians and 415 technologists were analyzed.
In a comparison between physicians and technologists, the video specificity, the still image sensitivity, and the percentage of category agreement did not show any significant differences. The video sensitivity, the still image specificity, and the percentage of disease name agreement were significantly higher in technologists. Observers who had experienced <100 cases showed significantly poorer results in all subjects except for the video specificity in physicians and the still image specificity in technologists.
Ultrasound technologists perform as well as physicians in recognizing and interpreting cancers on breast ultrasound, which supports their role in performing the initial screening examination.
为了提高乳腺癌超声筛查的质量，对超声检查人员进行有效的培训和评估其表现至关重要。
日本乳腺甲状腺超声协会的教育委员会（一个 NPO）已经建立了为期 2 天的乳腺超声培训计划，并在课程结束时进行测试。这些测试使用图像来评估观察者在超声中检测和评估病变的能力。使用视频检查检测病变的能力，使用静态图像检查评估病变的能力。分析了 422 名医生和 415 名技术员的测试结果。
在医生和技术员之间的比较中，视频特异性、静态图像敏感性和分类一致性百分比没有显示出任何显著差异。技术员的视频敏感性、静态图像特异性和疾病名称一致性百分比显著更高。除了医生的视频特异性和技术员的静态图像特异性外，经验不足 100 例的观察者在所有受试者中的表现都明显较差。
超声技术员在识别和解释乳腺超声中的癌症方面与医生一样出色，这支持了他们在进行初始筛查检查中的作用。
