目得：比较数字乳腺X线片的速度和准确性的解释由放射科医生通过使用打印胶片与软拷贝Display.Materials和方法：在数字乳腺X线片的解释培训后，8名放射科医生解释63个数字乳腺X线片，所有与旧的研究进行比较。所有研究均由所有阅片人以软拷贝和印刷胶片显示的形式进行解读，相同病例的图像解读至少间隔1个月。乳腺X线片的解释包括6例活检证实的癌症和20例活检证实的良性病变，20例可能是良性的患者进行了6个月的随访结果，17例没有明显的结果。软拷贝和印刷胶片显示器的受试者工作特征曲线下的面积（A，），灵敏度和特异性进行了计算。结果：没有显着差异的解释速度，但解释与软拷贝显示器稍快。在A，灵敏度和特异性的差异没有显着差异; A，和灵敏度稍好的解释与印刷胶片，和特异性稍好的解释与软copy.CONCLUSION：解释与软拷贝显示可能是有用的数字乳腺X射线摄影，是不太可能显着改变的准确性或速度。(C)RSNA，2002年。
PURPOSE: To compare the speed and accuracy of the interpretations of digital mammograms by radiologists by using printed-film versus soft-copy display.MATERIALS AND METHODS: After being trained in interpretation of digital mammograms, eight radiologists interpreted 63 digital mammograms, all with old studies for comparison. All studies were interpreted by all readers in soft-copy and printed-film display, with interpretations of images in the same cases at least I month apart. Mammograms were interpreted in cases that included six biopsyproved cancers and 20 biopsy-proved benign lesions, 20 cases of probably benign findings in patients who underwent 6-month follow-up, and 17 cases without apparent findings. Area under the receiver operating characteristic curve (A,), sensitivity, and specificity were calculated for soft-copy and printed-film display.RESULTS: There was no significant difference in the speed of interpretation, but interpretations with soft-copy display were slightly faster. The differences in A,, sensitivity, and specificity were not significantly different; A, and sensitivity were slightly better for interpretations with printed film, and specificity was slightly better for interpretations with soft copy.CONCLUSION: Interpretation with soft-copy display is likely to be useful with digital mammography and is unlikely to significantly change accuracy or speed.
