The ability of five low-dose mammographic screen--film systems to portray normal and abnormal breast structures was evaluated in parallel with a study of physical image properties. Single-blind evaluations of the visibility of normal breast architecture, mass lesions, and calcifications were made on the mammograms of 100 patients radiographed with each of the systems. There was increased noise and slightly poorer resolution for the faster recording systems, but there was no difference in final diagnostic impressions among the five systems. These results suggest that the faster systems will result in substantial dose reduction without sacrificing diagnostic accuracy.
对五种低剂量乳腺钼靶屏-片系统描绘正常和异常乳腺结构的能力进行了评估，并同时研究了其物理图像特性。在使用每种系统进行乳腺X线摄影的100例患者的乳房X线照片上，对正常乳腺结构、肿块病变和钙化的可见性进行了单盲评估。更快的记录系统存在噪声增加和分辨率略差的情况，但这五种系统在最终诊断印象上没有差异。这些结果表明，更快的系统将在不牺牲诊断准确性的情况下大幅降低剂量。
