Lightscanning is a new technique for breast diagnosis. The breast is illuminated with low-intensity light, and the transmission pattern of relatively narrow bands of red and infrared light is detected, amplified, reconstructed, and displayed in visual wavelengths. With a prototype scanner, 1200 patients referred for xeromammography were examined. All patients had both a lightscan and a xeromammogram obtained on the same day, and the examinations were interpreted blindly and in combination. Thirty-three patients had biopsy-proven cancer. The sensitivity and specificity of the nonblind lightscan and the xeromammogram were comparable. The sensitivity of the blind lightscan was poorer than the other two examinations for tumors smaller than 10 mm and for nonpalpable tumors. The technique of lightscanning is discussed and recommendations for further evaluation are made.
光扫描是一种用于乳腺诊断的新技术。用低强度光照射乳房，检测、放大、重建相对较窄波段的红光和红外光的透射模式，并在可见光波长下显示。使用一台原型扫描仪，对1200名转诊接受干板乳腺摄影的患者进行了检查。所有患者均在同一天进行了光扫描和干板乳腺摄影，且检查结果由专人独立盲法解读并综合分析。33例患者经活检证实患有癌症。非盲法光扫描和干板乳腺摄影的敏感性和特异性相当。对于小于10毫米的肿瘤和不可触及的肿瘤，盲法光扫描的敏感性低于其他两项检查。文中讨论了光扫描技术，并提出了进一步评估的建议。
