    2. Detection of cervical intraepithelial neoplasia by using optical coherence tomography in combination with microscopy

      Detection of cervical intraepithelial neoplasia by using optical coherence tomography in combination with microscopy
      Optical coherence tomography (OCT) is a noninvasive high-resolution imaging technique that permits the detection of cancerous and precancerous lesions of the uterine cervix. The purpose of this study was to evaluate a new system that integrates an OCT device into a microscope. OCT images were taken from loop electrosurgical excision procedure (LEEP) specimens under microscopic guidance. The images were blinded with respect to their origin within the microscopic image and ...

    3. Backscattering intensity measurements in optical coherence tomography as a method to identify parathyroid glands

      Backscattering intensity measurements in optical coherence tomography as a method to identify parathyroid glands
      Background and Objective Previous studies have shown that the use of optical coherence tomography (OCT) permits the differentiation between parathyroid tissue, thyroid tissue, lymph nodes and adipose tissue. We investigated the backscattering intensity profiles of OCT images in order to determine whether significant differences between these tissue types exist. Methods Mean backscattering intensity profiles were obtained from OCT images of parathyroid glands, thyroid tissue, lymph nodes and adipose tissue. The ...

    4. Effect of optical clearing agents on optical coherence tomography images of cervical epithelium

      Effect of optical clearing agents on optical coherence tomography images of cervical epithelium
      Optical coherence tomography (OCT) can be used as an adjunct to colposcopy in order to detect precancerous and cancerous cervical lesions. Optical clearing agents (OCAs) temporarily reduce the optical scattering of biological tissues. The purpose of this study was to investigate their influence on OCT imaging. OCT images were taken from unsuspicious and suspicious areas of fresh conization specimens immediately after resection and 5, 10, and 20 min after application ...

    5. Intraoperative optical coherence tomography imaging to identify parathyroid glands

      Intraoperative optical coherence tomography imaging to identify parathyroid glands
      Objective Optical coherence tomography (OCT) is a non-invasive high-resolution imaging technique that permits characterization of microarchitectural features in real time. Previous ex vivo studies have shown that the technique is capable of distinguishing between parathyroid tissue, thyroid tissue, lymph nodes, and adipose tissue. The purpose of this study was to evaluate the practicality of OCT during open and minimally invasive parathyroid and thyroid surgery. Methods During parathyroid and thyroid surgery ...

    6. Effect of acetic acid on optical coherence tomography (OCT) images of cervical epithelium

      Effect of acetic acid on optical coherence tomography (OCT) images of cervical epithelium
      Optical coherence tomography (OCT) can be used as an adjunct to colposcopy in the identification of precancerous and cancerous cervical lesions. The purpose of this study was to investigate the effect of acetic acid on OCT imaging. OCT images were taken from unsuspicious and suspicious areas of fresh conization specimens immediately after resection and 3 and 10 min after application of 6 % acetic acid. A corresponding histology was obtained from ...

    7. Optical coherence tomography as a method to identify parathyroid glands

      Optical coherence tomography as a method to identify parathyroid glands
      Background and Objective The identification of parathyroid glands can be a major problem in parathyroid surgery. The purpose of this study was to evaluate the feasibility of optical coherence tomography (OCT) in distinguishing between parathyroid tissue, thyroid tissue, lymph nodes, and adipose tissue. Methods Ex vivo OCT images as well as histological sections were generated from parathyroid glands, thyroid tissue, lymph nodes and fat in order to define significant morphologic ...

    8. Validation of an ex vivo human cervical tissue model for optical imaging studies

      Validation of an ex vivo human cervical tissue model for optical imaging studies
      Objective To establish and validate an ex vivo human cervical tissue model for optical coherence tomography (OCT) studies with special emphasis on investigating time dependent structural changes of the epithelium. Methods Four hundred OCT images were taken from 80 unsuspicious and suspicious areas of 18 fresh conisation specimens immediately after resection (0 hour) and 1, 2, 3, and 4 hours, referred to as waiting times in the following, postoperatively and ...

    11. Optical coherence tomography for the diagnosis of cervical intraepithelial neoplasia

      Optical coherence tomography for the diagnosis of cervical intraepithelial neoplasia
      Background and Objectives Optical coherence tomography (OCT) permits high-resolution imaging of tissue subsurfaces up to 2 mm in depth. The purpose of this study was to evaluate the accuracy and reproducibility of OCT in the characterization of cervical intraepithelial neoplasia (CIN) and to distinguish between different CIN grades. Study Design/Materials and Methods Colposcopy-guided OCT images were taken from unsuspicious and suspicious areas in women with suspected CIN. Each woman ...

    12. Optical coherence tomography: preliminary results with a new noninvasive technique for evaluating uterine cervical tissue and vulvar epithelium

      Optical coherence tomography: preliminary results with a new noninvasive technique for evaluating uterine cervical tissue and vulvar epithelium
      (Article in Itialian) AIM: Optical coherence tomography (OCT) is a noninvasive diagnostic imaging technique that captures high-definition real-time images at near-microscopic resolution (1-2 mm below the surface) of biological tissue morphology. The aim of this study was to define the characteristics of uterine cervical and vulvar pathologies by means of OCT and to compare OCT findings versus histopathological features. MATERIALS AND METHODS: This prospective single-center study was approved by the ...
