To assess whether radiologic technologists could be successfully trained to identify abnormalities on mammograms.
Eight radiologic technologists from two different institutions took a pretest, underwent an 8-hour training course followed by a period of preceptorship, and then took a posttest. Seven radiologists also took the pretest and posttest, which consisted of evaluating 1,238 two-view screening examinations, including 318 biopsy-proved cancers.
Overall, technologists at institution 1 had lower sensitivity (78%) at the pretest, which improved at the posttest (90%). Technologists at institution 2 had lower specificity at the pretest (44%), which improved on the posttest (64%). Hypothetical pairing of radiologists and technologists with use of posttest results revealed an increase in sensitivity (median increase, 12% at institution 1 and 19% at institution 2).
Formalized training successfully modified the technologists' skills. Radiologic technologists could be used to increase the number of breast cancers detected at screening mammography.
评估放射技师是否能够通过培训成功识别乳腺钼靶片中的异常情况。
来自两个不同机构的八名放射技师进行了预测试，参加了为期8小时的培训课程，随后进行了一段时间的带教实习，然后进行了后测试。七名放射科医生也参加了预测试和后测试，测试内容为评估1238例双视图筛查检查，其中包括318例经活检证实的癌症病例。
总体而言，机构1的技师在预测试时灵敏度较低（78%），后测试时有所提高（90%）。机构2的技师在预测试时特异度较低（44%），后测试时有所提高（64%）。根据后测试结果对放射科医生和技师进行假设配对后发现，灵敏度有所提高（机构1中位数提高12%，机构2中位数提高19%）。
正规培训成功提升了技师的技能。放射技师可用于增加乳腺钼靶筛查中检测出的乳腺癌数量。
