乳腺癌的早期诊断是提高妇女生活品质、降低死亡率的重要环节.作为乳腺癌主流诊断技术的钼靶软X射线诊断(mammography)对人体具有射线损伤,而近红外影像诊断(CDI)是无损伤、可反复检查的新诊断技术,但假阳性率偏高,目前受到医学界的质疑.文章从影像诊断的物理基础入手,讨论了癌症病变组织的生长、转移和血管分布异常对于近红外光透过率的影响,分析了CDI的优缺点,并从理论上得出了该技术满足影像诊断三要素的结论.文章作者还评述了市场竞争因素对于这一技术发展的影响,最后简单提及物理学在与生命科学交叉领域的研究课题和发展机会.
Early diagnosis of breast cancer is an important part of improving women’s quality of life and reducing mortality.Malmmography as a mainstream diagnostic technique for breast cancer has ray damage to the human body and near infrared imaging diagnosis (CDI) is none But the false positive rate is high, so it is being challenged by the medical community at present.This article starts with the physical basis of imaging diagnosis, and discusses the abnormal growth, metastasis and abnormal vascular distribution of cancer tissue. For the near infrared light The author analyzes the advantages and disadvantages of CDI and draws the conclusion that the technology meets the three elements of image diagnosis theoretically.The article also reviews the impact of market competition on the development of this technology, Physics in the field of cross-cutting and life science research topics and development opportunities.
