NLO microscopes provide complementary information about tissue microstructure, showing distinctive patterns for different types of human breast cancer, mucinous ovarian tumors, and skin dermis of patients with OI. Using a set of scoring methods (anisotropy, correlation, uniformity, entropy, and lifetime components), we found significant differences in the content, distribution and organization of collagen fibrils in the stroma of breast and ovary as well as in the dermis of skin. We suggest that our results provide a framework for using NLO techniques as a clinical diagnostic tool for human cancer and OI. We further suggest that the SHG and FLIM metrics described could be applied to other connective or epithelial tissue disorders that are characterized by abnormal cells proliferation and collagen assembly.<\/jats:p>","DOI":"10.1117\/1.jbo.17.8.081407","type":"journal-article","created":{"date-parts":[[2012,5,21]],"date-time":"2012-05-21T18:33:37Z","timestamp":1337625217000},"page":"1-10","source":"Crossref","is-referenced-by-count":24,"title":["Quantitative changes in human epithelial cancers and osteogenesis imperfecta disease detected using nonlinear multicontrast microscopy"],"prefix":"10.1117","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2176-2226","authenticated-orcid":false,"given":"Javier F.","family":"Adur","sequence":"first","affiliation":[{"name":"Univ.
