  Optical Coherence Tomography (OCT) is an established non-destructive and contactless photonic technique which has now been shown to be suitable for monitoring the near-surface internal structure of tissues in stored fruit and vegetables. Such real-time cross-sectional imaging allows for better visualisation and understanding of the temporal changes in internal structure. However, despite these advantages, problems persist around the trade-off between imaging resolution and penetration depth, image analysis and data processing ...

  Objectives The purpose of this study was to assess neoatherosclerosis in a registry of prospectively enrolled patients presenting with stent thrombosis using optical coherence tomography . Background In-stent neoatherosclerosis was recently identified as a novel disease manifestation of atherosclerosis after coronary stent implantation. Methods Angiography and intravascular optical coherence tomography were used to investigate etiologic factors of neoatherosclerosis in patients presenting with stent thrombosis 1 year after implantation (very late stent ...

4. Optical Coherence Tomography Angiography in Glaucoma: A Review
  
  Explore Karger Publishers Jun 5 2018 Ophthalmology
  
  Background: Glaucoma is the leading cause of irreversible blindness worldwide. Several techniques exist for the diagnosis and follow-up of patients. Optical coherence tomography (OCT) angiography (OCTA) is a recently developed technique that provides a quantitative assessment of the microcirculation of the retina and choroid in a fast, noninvasive way. Despite it being a novel technique, several publications have already been done in the glaucoma field. However, a summary of findings ...

  Objectives We evaluated healing responses with optical coherence tomography, and long-term clinical outcomes after treatment with a dedicated stent versus a conventional culotte technique. Background Dedicated bifurcation stents have been proposed as an alternative treatment for coronary bifurcation lesions. The long-term performance of dedicated stents versus conventional dual-stent techniques for the treatment of complex coronary bifurcation lesions is unknown. Methods Forty patients with true coronary bifurcation lesions were randomized to ...

  $In-stent fractional flow reserve variations and related optical coherence tomography findings: the FFR–OCT co-registration study$
  We sought to assess in-stent variations in fractional flow reserve (FFR) in patients with previous percutaneous coronary intervention (PCI) and to associate any drop in FFR with findings by optical coherence tomography (OCT) imaging. Suboptimal post-PCI FFR values were previously associated with poor outcomes. It is not known to which extent in-stent pressure loss contributes to reduced FFR. In this single-arm observational study, 26 patients who previously underwent PCI with ...

  Background Stent thrombosis (ST) is a serious complication following coronary stenting. Intravascular optical coherence tomography (OCT) may provide insights into mechanistic processes leading to ST. We performed a prospective, multicenter study to evaluate OCT findings in patients with ST. Methods Consecutive patients presenting with ST were prospectively enrolled in a registry using a centralized telephone registration system. After angiographic confirmation of ST, OCT imaging of the culprit vessel was performed ...

  Objective: In this work, we perform margin assessment of human breast tissue from optical coherence tomography (OCT) images using deep neural networks (DNNs). This work simulates an intraoperative setting for breast cancer lumpectomy. Methods: To train the DNNs, we use both the state-of-the-art methods (Weight Decay and DropOut) and a newly introduced regularization method based on function norms. Commonly used methods can fail when only a small database is available ...

  $Anatomical and functional assessment of Tryton bifurcation stent before and after final kissing balloon dilatation: Evaluations by three-dimensional coronary angiography, optical coherence tomography imaging and fractional flow reserve$
  Objectives To assess the anatomical and functional impact of final kissing balloon inflation (FKBI) after implantation of a dedicated bifurcation stent system. Background Current evidence suggests clinical benefit of FKBI in patients undergoing bifurcation dilatation using the Tryton side branch stent (Tryton-SBS). We hypothesized that FKBI improves anatomical reconstruction and functional results of bifurcation treated by Tryton-SBS. Methods An unselected group of patients with complex bifurcation coronary lesions undergoing percutaneous ...

  Objective There is an ongoing controversy regarding the efficacy and safety of different percutaneous stenting techniques for coronary bifurcation lesions needing 1 stent. The promise of safe vessel restoration with bioresorbable scaffolds (BRS) may not be transferable to complex double BRS bifurcation techniques, and permanent metallic scaffolding of the bifurcation core may be needed. We identified modified-T stenting as the most promising fully bioresorbable 2-stent strategy in a preclinical setting ...

  Bifurcation lesions are associated with increased procedural complications and worse long-term outcome. Multiple techniques are available, including the dedicated drug-eluting Axxess stent system (Biosensors International Ltd., Singapore, Singapore), providing complete bifurcation support without covering the carina. Low rates of restenosis in both main vessel (MV) and side branch (SB) have been demonstrated. High-resolution imaging techniques such as intravascular optical coherence tomography (IV-OCT) may help the positioning and implantation of the ...

  Pre-harvest growing conditions during the development of fruit have impacts on fruit quality at the time of harvest and during storage. These impacts may result in differences in the skin properties of the fruit and some sub-surface cellular structural changes, which have potential effects on postharvest fruit quality and storability.
