使用ＬＸ－７６７Ｂ型电脑近红外线乳腺检查仪共检查门诊病人５１２例，诊断乳腺癌４２例，其中假阳性４例，诊断符合率９０．５％。乳腺癌的近红外图像主要表现为肿块的灰影与血管改变，分析图像时应着重观察两者间的关系，该检查的诊断符合率高于针吸及Ｘ线钼靶片，且无创伤、无痛苦、无射线损伤，可作乳腺癌检查之首选。 A total of 512 outpatients were examined using the LX-767B computer-based near-infrared mammography system. 42 cases of breast cancer were diagnosed, including 4 cases with false positives. The diagnostic compliance rate was 90.5%. The near-infrared image of breast cancer is mainly manifested as the gray shade and blood vessel changes of the mass. The analysis of the image should focus on the relationship between the two. The diagnostic accuracy of the examination is higher than that of the needle-absorption and X-ray molybdenum target, and it is non-invasive. No pain, no radiation damage, can be used as the first choice for breast cancer examination.
