    1. Complementary Study of Collagen State in Bladder Diseases Using Cross-Polarization Optical Coherence Tomography, Nonlinear and Atomic Force Microscopy

      Complementary Study of Collagen State in Bladder Diseases Using Cross-Polarization Optical Coherence Tomography, Nonlinear and Atomic Force Microscopy

      The aim of the study is to demonstrate the potential of cross-polarization optical coherence tomography (CP OCT) as a minimally invasive real-time technique for detection of bladder cancer against a background of severe inflammation. Materials and Methods. For the verification of CP OCT diagnostic data related to the condition of collagen comparison with high-resolution microscopy inspection was performed and correlation of the results was calculated. The CP OCT study was performed on samples of tissue with muscle-invasive urothelial carcinoma T 2–3 N 0–х M 0 (G2, 3) in 18 patients ranging in age from 50 to 64 obtained ...

    2. Quantitative Evaluation of the Polarization Characteristics of Coronary Arteries Atherosclerotic Plaques at Different Development Stages

      Quantitative Evaluation of the Polarization Characteristics of Coronary Arteries Atherosclerotic Plaques at Different Development Stages

      The aim of the investigation was to develop an approach to quantitative evaluation of polarization properties (birefringence and cross-scattering) basing on cross-polarization OCT images (CP OCT) in order to characterize the development stages of atherosclerotic plaques and to reveal unstable ones. Materials and Methods. We report on quantitative analysis of CP OCT images of the seven development stages of atherosclerotic plaques ex vivo . Integral depolarization factor (IDF) and effective birefringence coefficient (Δ n ) were proposed as parameters for quantitative characterization of the CP OCT images. Results. Calculation of the IDF and Δ n in the local region of interest (intima/fibrous cap ...

    3. The Use of Cross-Polarization OCT in Determining the Dynamics of the State of Pathological and Normal Tissues During Radiation and Photodynamic Therapy

      The Use of Cross-Polarization OCT in Determining the Dynamics of the State of Pathological and Normal Tissues During Radiation and Photodynamic Therapy

      The aim of the investigation was to evaluate the possibilities for using cross-polarization optical coherence tomography (CP OCT) to monitor the effectiveness of treatment of cancer of the mouth cavity and of the cervix uteri after photodynamic therapy (PDT) and radiation therapy (RT). Materials and Methods. The CP OCT investigation was performed with an OCT-1300U (Institute of Applied Physics of the Russian Academy of Sciences, LLC “Biomedtech”, Russia) tomograph. The monitoring of the two types of treatment was performed after different periods of exposure: for RT of the mouth cavity cancer — once every 2–3 days throughout the whole course ...
