      In vivo time-serial multi-modality optical imaging in a mouse model of ovarian tumorigenesis

      Identification of the early microscopic changes associated with ovarian cancer may lead to development of a diagnostic test for high-risk women. In this study we use optical coherence tomography (OCT) and multiphoton microscopy (MPM) (collecting both two photon excited fluorescence [TPEF] and second harmonic generation [SHG]) to image mouse ovaries in vivo at multiple time points. We demonstrate the feasibility of imaging mouse ovaries in vivo during a long-term survival study and identify microscopic changes associated with early tumor development. These changes include alterations in tissue microstructure, as seen by OCT, alterations in cellular fluorescence and morphology, as seen by ...

    2. Simultaneous optical coherence tomography and laser induced fluorescence imaging in rat model of ovarian carcinogenesis

      Simultaneous optical coherence tomography and laser induced fluorescence imaging in rat model of ovarian carcinogenesis
      Determining if an ovarian mass is benign or malignant is an ongoing clinical challenge. The development of reliable animal models provides means to evaluate new diagnostic tools to more accurately determine if an ovary has benign or malignant features. Although sex cord-stromal tumors (SCST) account for 0.1-0.5% of ovarian malignancies, they have similar appearances to more aggressive epithelial cancers and can serve as a prototype for developing better diagnostic methods for ovarian cancer. Optical coherence tomography (OCT) and laser-induced fluorescence (LIF) spectroscopy are non-destructive optical imaging modalities. OCT provides architectural cross-sectional images at near histological resolutions and LIF ...

    3. Serial Endoscopy in Azoxymethane Treated Mice Using Ultra-High Resolution Optical Coherence Tomography

      Serial Endoscopy in Azoxymethane Treated Mice Using Ultra-High Resolution Optical Coherence Tomography

      Purpose: Optical coherence tomography (OCT) is a minimally invasive, depth-resolved imaging tool that can be implemented in a small diameter endoscope for imaging mouse models of colorectal cancer (CRC). In this study, we utilized ultrahigh resolution (UHR) OCT to serially image the lower colon of azoxymethane (AOM) treated A/J mouse models of CRC in order to monitor the progression of neoplastic transformations and determine if OCT is capable of identifying early disease. Experimental Design: Thirteen AOM treated A/J and two control A/J mice were surveyed at four timepoints (8, 14, 22, and 26 weeks post AOM treatment ...
