Example inverse FF-OCT images (left column) and corresponding histology images (right column) of ovarian metastases. An ovary containing a solitary metastasis originating from a primary invasive breast carcinoma is shown in A and B (indicated by arrows). An ovary in which disseminated breast tumor cells are dispersed throughout the ovary is shown in C and D. Micrometastases originating from a primary endometrial carcinoma are shown in E and F (indicated by arrows); scale bars, 500 (A–D) and 200 μm (E–F). Inge T.A. Peters et al.
