An acceptable mammography film digitizer must provide high-quality images at a level of diagnostic accuracy comparable to reading conventional film examinations. The purpose of this study was to determine if there are significant differences between the interpretations of conventional film-screen mammography examinations and soft copy readings of the images produced by a mammography film digitizer. Eight radiologists interpreted 120 mammography examinations, half as original films and the other half as digital images on a soft copy work station. No radiologist read the same examination twice. The interpretations were recorded in accordance with the Breast Imaging Reporting and Data System and included other variables such as perceived image quality and diagnostic difficulty and confidence. The results provide support for the hypothesis that there are no significant differences between the interpretations of conventional film-screen mammography examinations and soft copy examinations produced by a mammography film digitizer.
一台合格的乳腺摄影胶片数字化仪必须能够提供高质量的图像，其诊断准确性要与解读传统胶片检查相当。本研究的目的是确定传统屏-片乳腺摄影检查的解读与乳腺摄影胶片数字化仪所产生图像的软拷贝解读之间是否存在显著差异。八位放射科医生解读了120例乳腺摄影检查，其中一半为原始胶片，另一半为在软拷贝工作站上的数字图像。没有放射科医生对同一检查进行两次解读。解读结果按照乳腺影像报告和数据系统进行记录，还包括其他变量，如感知到的图像质量、诊断难度和信心。结果支持了这样一个假设，即传统屏-片乳腺摄影检查的解读与乳腺摄影胶片数字化仪所产生的软拷贝检查的解读之间不存在显著差异。
