Nonpalpable, low-density, noncalcified lesions sometimes can be difficult to see on an initial specimen radiograph. In 57 consecutive wire localizations, 37 patients had obvious microcalcifications and did not require a second specimen radiograph. Twenty-six patients had nonpalpable, noncalcified lesions, and a second specimen radiograph was obtained in 24 of these. In four of these cases the initial specimen radiograph failed to show the suspected lesion, and a second specimen radiograph orthogonal to the original plane of orientation of the specimen showed the lesion to be contained within the biopsied material. Although it is seldom necessary to use this technique, it may obviate a second biopsy specimen as well as reduce operative time. We found that a second orthogonal specimen radiograph provided important information in 7% of cases.
触诊不清、低密度、非钙化的病变有时在最初的标本X光片上很难看清。在连续57例金属丝定位病例中，37例患者有明显的微钙化，不需要进行第二次标本X光检查。26例患者有触诊不清的非钙化病变，其中24例进行了第二次标本X光检查。在其中4例中，最初的标本X光片未能显示出可疑病变，而与标本原始定向平面正交的第二次标本X光片显示病变包含在活检材料内。尽管很少需要使用这种技术，但它可以避免进行第二次活检标本采集，并减少手术时间。我们发现，第二次正交标本X光片在7%的病例中提供了重要信息。
