    1. Diagnostic potential of multimodal imaging of ovarian tissue using optical coherence tomography and second-harmonic generation microscopy

      Diagnostic potential of multimodal imaging of ovarian tissue using optical coherence tomography and second-harmonic generation microscopy

      Ovarian cancer is particularly deadly because it is usually diagnosed after it has metastasized. We have previously identified features of ovarian cancer using optical coherence tomography (OCT) and second-harmonic generation (SHG) microscopy (targeting collagen). OCT provides an image of the ovarian microstructure, while SHG provides a high-resolution map of collagen fiber bundle arrangement. Here, we investigated the diagnostic potential of dual-modality OCT and SHG imaging. We conducted a fully crossed, multireader, multicase study using seven human observers. Each observer classified 44 ex vivo mouse ovaries (16 normal and 28 abnormal) as normal or abnormal from OCT, SHG, and simultaneously viewed ...

    2. In vivo three-dimensional optical coherence tomography and multiphoton microscopy in a mouse model of ovarian neoplasia

      In vivo three-dimensional optical coherence tomography and multiphoton microscopy in a mouse model of ovarian neoplasia

      Our goal is to use optical coherence tomography (OCT) and multiphoton microscopy (MPM) to detect early tumor development in a mouse model of ovarian neoplasia. We hope to use information regarding early tumor development to create a diagnostic test for high-risk patients. In this study we collect in vivo images using OCT, second harmonic generation and two-photon excited fluorescence from non-vinylcyclohexene diepoxide (VCD)-dosed and VCD-dosed mice. VCD causes follicular apoptosis (simulating menopause) and leads to tumor development. Using OCT and MPM we visualized the ovarian microstructure and were able to see differences between non-VCD-dosed and VCD-dosed animals. This leads ...

    3. In Vivo, Dual-Modality OCT/LIF Imaging Using a Novel VEGF Receptor-Targeted NIR Fluorescent Probe in the AOM-Treated Mouse Model

      In Vivo, Dual-Modality OCT/LIF Imaging Using a Novel VEGF Receptor-Targeted NIR Fluorescent Probe in the AOM-Treated Mouse Model
      Purpose: Increased vascular endothelial growth factor (VEGF) receptor expression has been found at the sites of angiogenesis, particularly in tumor growth areas, as compared with quiescent vasculature. An increase in VEGF receptor-2 is associated with colon cancer progression. The in vivo detection of VEGF receptor is of interest for the purposes of studying basic mechanisms of carcinogenesis, making clinical diagnoses, and monitoring the efficacy of chemopreventive and therapeutic agents. In this study, a novel single chain (sc)VEGF-based molecular probe is utilized in the azoxymethane (AOM)-treated mouse model of colorectal cancer to study delivery route and specificity for disease ...
