对使用 Fuji 高分辨率 BAFBr:EU2+ 成像板数字化的 40 个不同放射密度乳房进行的初步研究使我们能够使用 Fuji Computer Radiology 201 系统建立可接受的增强程序。其中 36 个乳房的屏幕电影图像也在 Damon DETECT 电视系统上进行了数字化和增强。三名专门从事乳房X线摄影的放射科医生审查了每对图像。对于 20 例正常检查，两种数字方法被认为在图像质量上相当，而对于 16 例包含病理（肿块和/或钙化）的病例，电视系统被认为提供最佳图像质量的频率是激光扫描系统的两倍。对于 8% 的图像，放射科医生拒绝了这两种增强方法。尽管两个系统之间的成本存在差异，但两者在穿透致密乳房方面具有相同的能力。然而，这两种系统都有几个重大缺陷，妨碍了它们的临床使用。目前，除了实验能力之外，没有任何客观理由可以使用这两种系统进行乳腺成像。
A preliminary study of 40 different radiodense breasts digitized with a Fuji high resolution BAFBr:EU2+ imaging plate enabled us to establish acceptable enhancement procedures with a Fuji Computer Radiology 201 system. Screen-film images of 36 of these breasts were also digitized and enhanced on a Damon DETECT TV system. Three radiologists specializing in mammography reviewed each pair of images. For the 20 normal examinations, both digital methods were considered equivalent in image quality, while for the 16 cases containing pathology (masses and/or calcifications) the TV system was considered to provide the best image quality twice as often as the laser scanned system. The radiologists rejected both methods of enhancement for 8% of the images. Despite cost differences between the two systems, both have equal capability in penetrating dense breasts. However, both systems have several significant deficiencies which preclude their clinical use. At the present time, there is no objective justification for using either system for breast imaging other than in an experimental capacity.
