    4. Is quantitative coronary angiography reliable in assessing the late lumen loss of the everolimus eluting bioresorbable polylactide scaffold in comparison with the cobalt chromium metallic stent?

      Explore eurointervention.org Cardiology
      Is quantitative coronary angiography reliable in assessing the late lumen loss of the everolimus eluting bioresorbable polylactide scaffold in comparison with the cobalt chromium metallic stent?
      Aims: Immediately after stent/scaffold implantation, quantitative coronary angiography (QCA) with respect to optical coherence tomography (OCT) more severely underestimates the lumen diameter (LD) in Absorb than in XIENCE. This OCT-QCA discrepancy has not been evaluated at long-term follow-up. The present study aimed to assess the accuracy of QCA with reference to OCT in Absorb as compared to XIENCE.

      Optical coherence tomography and confocal laser endomicroscopy in pulmonary diseases
      Purpose of review: Current imaging techniques (X-ray, computed tomography scan, ultrasound) have limitations in the identification and quantification of pulmonary diseases, in particular, on highly detailed level. The purpose of this review is to provide an overview of the current knowledge of innovative light- and laser-based imaging techniques that might fill this gap. Recent findings: Optical coherence tomography (OCT) and confocal laser endomicroscopy (CLE) are high-resolution imaging techniques, which, combined ...

      Feasibility of laser marking in Barrett’s esophagus with volumetric laser endomicroscopy: first-in-man pilot study
      Background and Aim Volumetric laser endomicroscopy (VLE) provides a circumferential scan of the esophageal wall layers and has potential to improve detection of neoplasia in Barretts esophagus (BE). The novel VLE laser marking system enables direct in vivo marking of suspicious areas as identified on VLE. These laser marked areas can subsequently be targeted for biopsies. The aim was to evaluate the visibility and positional accuracy of laser marks (LMs ...

      Intracoronary optical coherence tomography: Clinical and research applications and intravascular imaging software overview
      By providing valuable information about the coronary artery wall and lumen, intravascular imaging may aid in optimizing interventional procedure results and thereby could improve clinical outcomes following percutaneous coronary intervention (PCI). Intravascular optical coherence tomography (OCT) is a light-based technology with a tissue penetration of approximately 1 to 3 mm and provides near histological resolution. It has emerged as a technological breakthrough in intravascular imaging with multiple clinical and research ...

      Non-moving scanner design for OCT systems
      n this work, a novel beam scanner design based on non-moving parts is introduced which will eliminate the phase and inaccuracy problems of the mechanical scanners while providing two times imaging speed improvement for optical coherence tomography systems. The design is comprised of electro-optically activated switches that are placed on the sample arm. For the example considered here, lateral resolution of 20 m, and lateral scanning range of 1 mm ...

      Design of a high-speed multiple-reference optical coherence tomography system
      he imaging speed of a time domain optical coherence tomography (OCT) system is limited by the speed of the moving mirror. As a solution to this problem an integrated-optics-based multiple-reference TD-OCT system is presented in this work. The reference and sample lights will be sequentially tapped out at multiple locations using electro-optically controlled switches. For the design considered here an axial resolution of 20 m and a depth range of ...

      Optical coherence tomography attenuation imaging for lipid core detection: an ex-vivo validation study
      Lipid-core atherosclerotic plaques are associated with disease progression, procedural complications, and cardiac events. Coronary plaque lipid can be quantified in optical coherence tomography (OCT) pullbacks by measurement of lipid arcs and lipid lengths; parameters frequently used in clinical research, but labor intensive and subjective to analyse. In this study, we investigated the ability of quantitative attenuation, derived from intravascular OCT, to detect plaque lipid. Lipid cores are associated with a ...

      Measurement of biofilm growth and local hydrodynamics using optical coherence tomography
      We report on localized and simultaneous measurement of biofilm growth and local hydrodynamics in a microfluidic channel using optical coherence tomography. We measure independently with high spatio-temporal resolution the longitudinal flow velocity component parallel to the imaging beam and the transverse flow velocity component perpendicular to the imaging beam. Based on the measured velocities we calculate the shear-rates in the flow channel. We show the relation between the measured biofilm ...

      Optical Coherence Tomography as a Tool for in Vivo Staging and Grading of Upper Urinary Tract Urothelial Carcinoma: A Study for Diagnostic Accuracy
      Purposes Biopsies and cytology are cornerstones in the diagnosis of upper urinary tract urothelial carcinoma (UTUC). However, a high rate of non-diagnostic biopsies, tumor upgrading and -staging after nephroureterectomy is observed. In this prospective in vivo study we aimed to evaluate the diagnostic accuracy of OCT for grading and staging of UTUC Material Methods Twenty-six patients underwent diagnostic URS including biopsies and OCT imaging, followed by nephroureterectomy or segmental ureter ...
