To compare the reading time for full-field digital mammography (FFDM) and screen-film mammography (SFM) using a recommended reading method and to provide data regarding the reading time required to establish the optimal conditions for digital mammography.
Reading time was measured during image interpretation by two expert radiologists. FFDM images were taken for screening, and readers A and B read images obtained for 79 and 82 patients, respectively. The mammograms read by both readers were similar with regard to patients' backgrounds. Further, 100 SFM mammograms were read to perform comparative analyses. The reading times were compared.
Reader A recorded mean reading times of 31 and 56 s, respectively, for the SFM and FFDM images with no comparative mammograms, and means of 45 and 62 s for those with comparative mammograms. Reader B recorded mean reading times of 43 and 74 s, respectively, for SFM and FFDM images with no comparative mammograms, and 53 and 66 s for those with comparative mammograms.
The reading time is prolonged in FFDM performed according to a recommended method. Post-processing is thought to affect the reading time.
使用推荐的阅片方法比较全视野数字乳腺摄影（FFDM）和屏-片乳腺摄影（SFM）的阅片时间，并提供有关为数字乳腺摄影确定最佳条件所需阅片时间的数据。
由两位放射科专家在图像解读过程中测量阅片时间。采集FFDM图像用于筛查，读者A和读者B分别阅读了79例和82例患者的图像。两位读者阅读的乳腺造影片在患者背景方面相似。此外，阅读了100例SFM乳腺造影片以进行对比分析。比较阅片时间。
读者A记录的无对比乳腺造影片的SFM和FFDM图像的平均阅片时间分别为31秒和56秒，有对比乳腺造影片的平均阅片时间分别为45秒和62秒。读者B记录的无对比乳腺造影片的SFM和FFDM图像的平均阅片时间分别为43秒和74秒，有对比乳腺造影片的平均阅片时间分别为53秒和66秒。
按照推荐方法进行的FFDM阅片时间会延长。后处理被认为会影响阅片时间。
