Mediolateral and craniocaudal film-screen mammograms and a mediolateral noncontact xeromammogram obtained for 53 women with breast cancer were randomly evaluated, alone and in combination, by four mammographers in a blind, randomized fashion. Cancer detection was improved the greater the number of views evaluated. Certain cancers, by virtue of their position in the breast, can be obscured by superimposed dysplastic tissue on one view while being detectable on another which images the breast in a different projection. Some cancers posterolaterally located within the breast may be obscured by the rib cage on the mediolateral noncontact xeromammogram, but may be easily identified on the mediolateral or craniocaudal film-screen mammograms. Other posteriorly situated carcinomas may be projected off the film edge on the mediolateral and craniocaudal film-screen mammograms performed with compression, but may be imaged on the mediolateral noncontact xeromammogram. Xeromammography better images fine detail and microcalcifications, while film-screen mammography permits greater broad-area contrast. A combined film-screen/xeromammographic examination optimizes complementary projections and imaging techniques.
对53名乳腺癌女性的内外侧位和头尾位乳腺X线钼靶片以及一张内外侧位非接触式干板乳腺造影片进行了随机评估，由四名乳腺造影师以盲法、随机方式单独或联合评估。评估的视图数量越多，癌症检测效果越好。某些癌症由于其在乳房中的位置，在一个视图上可能会被重叠的发育异常组织遮挡，而在以不同投影方式成像乳房的另一个视图上则可被检测到。一些位于乳房后外侧的癌症在内外侧非接触式干板乳腺造影片上可能会被肋骨遮挡，但在内外侧位或头尾位乳腺X线钼靶片上可能很容易识别。其他位于后方的癌灶在用压迫法进行的内外侧位和头尾位乳腺X线钼靶片上可能会投影到胶片边缘之外，但在内外侧非接触式干板乳腺造影片上可能会成像。干板乳腺造影能更好地显示细微细节和微钙化，而乳腺X线钼靶片则能提供更大的大面积对比度。乳腺X线钼靶片/干板乳腺造影联合检查可优化互补投影和成像技术。
