PURPOSE
Determination of image quality between conventional film screen system, digital phosphor storage plate mammography (high resolution) and digital mammography.
MATERIALS AND METHODS
Mammograms of the Wisconsin Mammographic Random Phantom, Model 152 A (Radiation Measurements Inc., Wisconsin) were acquired using a conventional film-screen system, a digital storage phosphor plate system and a digital system.
RESULTS
Of 225 possible details, 191/a 38.2, 193/a 38.6, and 202/a 40.4 details were detected with conventional film-screen system, digital phosphor storage plate mammography and digital mammography, respectively. There was no significant difference (p < 0,058). The entrance surface air kerma was 9.64 mGy, 7.60 mGy and 7.02 mGy, respectively.
CONCLUSIONS
Based on these results, conventional film-screen system can be replaced with both digital phosphor storage plate mammography and digital mammography, to be confirmed with further clinical trials.
目的
比较传统胶片屏系统、数字磷光存储板乳腺摄影（高分辨率）和数字乳腺摄影的图像质量。
材料与方法
使用传统胶片屏系统、数字存储磷光板系统和数字系统获取威斯康星乳腺摄影随机体模（152 A型，威斯康星辐射测量公司）的乳腺造影片。
结果
在225个可能的细节中，传统胶片屏系统、数字磷光存储板乳腺摄影和数字乳腺摄影分别检测到191个/38.2%、193个/38.6%和202个/40.4%的细节。差异无统计学意义（p < 0.058）。入射表面空气比释动能分别为9.64 mGy、7.60 mGy和7.02 mGy。
结论
基于这些结果，传统胶片屏系统可被数字磷光存储板乳腺摄影和数字乳腺摄影所取代，有待进一步临床试验证实。
