To compare the advantages of one-view vs two-view mammography screening, films were reviewed for 2500 consecutive asymptomatic women undergoing baseline mammography. To provide screening at low cost, examinations were limited to two radiographs per breast, one each in the craniocaudal and mediolateral oblique projections, with the understanding that those few patients with detected abnormalities would require additional mammograms, taken with an individually directed, problem-solving approach, at considerably higher cost. Two separate interpretations were made of each case, one using only the oblique projection images, the other using both oblique and craniocaudal views. Two-view interpretations not only identified more cancers than one-view readings (27 vs 25), they also required fewer additional mammograms to evaluate potential abnormalities (179 vs 642, 7% vs 26%). These advantages outweigh the additional radiation risk and added cost. Baseline screening mammography should be done with two views per breast.
为比较单视角与双视角乳腺钼靶筛查的优势，对2500名连续接受基线乳腺钼靶检查的无症状女性的影像进行了回顾。为了以低成本进行筛查，每个乳房的检查限于两张X光片，分别为头尾位和内外侧斜位各一张，前提是少数检测出异常的患者需要额外的钼靶片，采用个体化针对性的解决问题方法拍摄，成本要高得多。对每个病例进行了两种独立解读，一种仅使用斜位投影图像，另一种同时使用斜位和头尾位视图。双视角解读不仅比单视角读数发现更多癌症（27例对25例），而且评估潜在异常所需的额外钼靶片也更少（179张对642张，7%对26%）。这些优势超过了额外的辐射风险和增加的成本。基线筛查乳腺钼靶检查应每个乳房采用双视角进行。
