The objective of this study is to compare image quality and lesion detection for full field digital mammography (FFDM) and film-screen mammography (FSM). In 200 women we performed digital mammography of one breast and film-screen mammography of the other breast. Imaging parameters were set automatically. Image quality, visualization of calcifications and masses were rated by three readers independently. Mean glandular dose was calculated for both systems. We found no significant difference in mean glandular dose. Image quality was rated by reader A/B/C as excellent for FFDM in 153/155/167 cases and for FSM in 139/116/114 cases (p<0.03/0.001/0.001). Microcalcifications were detected by FFDM in 103/89/98 and by FSM in 76/76/76 cases (p<0.01/0.06/0.01). Detection of masses did not differ significantly. FFDM provided significantly better visibility of skin and nipple-areola region (p<0.01). FFDM demonstrated improved image quality compared with film-screen mammography. Microcalcification detection was also significantly better with the digital mammography system for two of the three readers.
本研究的目的是比较全视野数字乳腺摄影（FFDM）和屏-片乳腺摄影（FSM）的图像质量及病灶检测能力。我们对200名女性进行了检查，一侧乳房采用数字乳腺摄影，另一侧乳房采用屏-片乳腺摄影。成像参数自动设置。由三位阅片者独立对图像质量、钙化灶及肿块的显示情况进行评分。计算两个系统的平均腺体剂量。我们发现平均腺体剂量无显著差异。阅片者A/B/C将FFDM的图像质量评为优的分别有153/155/167例，将FSM的图像质量评为优的分别有139/116/114例（p<0.03/0.001/0.001）。FFDM检测出微钙化灶的分别有103/89/98例，FSM检测出微钙化灶的分别有76/76/76例（p<0.01/0.06/0.01）。肿块检测无显著差异。FFDM对皮肤及乳头-乳晕区的显示明显更好（p<0.01）。与屏-片乳腺摄影相比，FFDM的图像质量更佳。三位阅片者中有两位认为数字乳腺摄影系统对微钙化灶的检测也明显更好。
