Diaphanography (lightscanning) is a noninvasive method of examining the breast by transillumination using visible or infrared light. It was compared to xeromammography in 1,000 patients, 91 of whom had biopsy. There were 34 malignant tumors, of which 29 were detected by xeromammography and 26 by lightscanning; 27 patients with positive lightscans were not biopsied. All patients with true-positive lightscans also had positive mammograms. Major criteria of malignancy on diaphanography included an area of light absorption and abnormal or hypervascularity. These criteria could be demonstrated on retrospect on 6 scans previously considered negative; one xeromammogram previously interpreted as negative was diagnosed as positive on retrospect. Diaphanography may be sensitive enough to warrant further investigation.
透照法（光扫描）是一种通过使用可见光或红外光进行透照来检查乳房的非侵入性方法。对1000名患者进行了透照法与干板乳房X线照相术的比较，其中91人进行了活检。共有34个恶性肿瘤，其中29个通过干板乳房X线照相术检测到，26个通过光扫描检测到；27名光扫描呈阳性的患者未进行活检。所有光扫描真阳性的患者乳房X线照片也呈阳性。透照法诊断恶性肿瘤的主要标准包括光吸收区域以及异常或血管增多。这些标准可在回顾时在之前被认为阴性的6次扫描中得到证实；一张之前被解释为阴性的干板乳房X线照片在回顾时被诊断为阳性。透照法可能足够敏感，值得进一步研究。
