  Explore Nature Publishing Group Apr 30 2022 Cardiology
  
  Since optical coherence tomography (OCT) was first performed in humans two decades ago, this imaging modality has been widely adopted in research on coronary atherosclerosis and adopted clinically for the optimization of percutaneous coronary intervention. In the past 10 years, substantial advances have been made in the understanding of in vivo vascular biology using OCT. Identification by OCT of culprit plaque pathology could potentially lead to a major shift in ...

5. Role of Multimodality Imaging in the Assessment of Myocardial Infarction With Nonobstructive Coronary Arteries: Beyond Conventional Coronary Angiography
  
  Explore Home | AHA/ASA Journals Dec 31 2021 Cardiology
  
  Myocardial infarction with nonobstructive coronary arteries (MINOCA) is a heterogeneous clinical entity, encompassing multiple different causes, and a cause of substantial morbidity and mortality. Current guidelines suggest a multimodality imaging approach in establishing the underlying cause for MINOCA, which is considered a working diagnosis. Recent studies have suggested that an initial workup consisting of cardiac magnetic resonance and invasive coronary imaging can yield the diagnosis in most patients. Cardiac magnetic ...

6. A multi-scale/multi-physics model for the theoretical study of the vascular configuration of retinal capillary plexuses based on OCTA data
  
  Explore Journals Dec 3 2021 Ophthalmology
  
  The retinal tissue is highly metabolically active and is responsible for translating the visual stimuli into electrical signals to be delivered to the brain. A complex vascular structure ensures an adequate supply of blood and oxygen, which is essential for the function and survival of the retinal tissue. To date, a complete understanding of the configuration of the retinal vascular structures is still lacking. Optical coherence tomography angiography has made ...

7. Optical coherence tomography
  
  Explore ScienceDirect Nov 23 2021 Dermatology
  
  During the past decade, noninvasive imaging has emerged as a valuable tool in clinical dermatology and dermatologic research. Optical coherence tomography (OCT) is one such type of noninvasive imaging. OCT uses the principle of interferometry to produce real-time images. A low-power diode laser shines infrared light onto tissues, which reflects back to an optical fiber interferometer. Using time delay and the backscattered light intensity, a two-dimensional image akin to an ...

8. Optical coherence tomography and coronary revascularization: from indication to procedural optimization
  
  Explore ScienceDirect Nov 8 2021 Cardiology
  
  Angiography alone is the most commonly used imaging modality for guidance of percutaneous coronary interventions. Angiography is limited, however, by several factors, including that it only portrays a low resolution, two-dimensional outline of the lumen and does not inform on plaque composition and functional stenosis severity. Optical coherence tomography (OCT) is an intracoronary imaging technique that has superior spatial resolution compared to all other imaging modalities. High-resolution imaging of the ...

10. Evaluating Onychomycosis Outcomes 2 Months into an 11-month-long Efinaconazole Regimen: The Role of Optical Coherence Tomography
  
  Explore jcadonline.com Sep 26 2021 Dermatology
  
  Background. Onychomycosis affects 43 million people in the United States and Europe. Topical therapies can be effective but require lengthy and costly regimens without an established method for predicting the treatment outcome. Objective. We studied the role of optical coherence tomography (OCT), a noninvasive imaging device approved by the United States Food and Drug Administration, in evaluating onychomycosis treatment outcomes. Methods. This investigator-initiated prospective clinical study recruited subjects from two ...

  Explore ScienceDirect Sep 22 2021 Cardiology
  
  Plaque rupture is the most common cause of acute coronary syndromes and sudden cardiac death. Characteristics and pathobiology of vulnerable plaques prone to plaque rupture have been studied extensively over 2 decades in humans using optical coherence tomography (OCT), an intravascular imaging technique with micron scale resolution. OCT studies have identified key features of plaque vulnerability and described the in vivo characteristics and spatial distribution of thin cap fibroatheromas as ...

  Explore ScienceDirect Sep 22 2021 Cardiology
  
  Plaque erosion, a distinct histopathological and clinical entity, accounts for over 30% of acute coronary syndromes (ACS). Optical coherence tomography allows in vivo diagnosis of plaque erosion. Local flow perturbation with activation of Toll-like receptor 2 and CD8 + T cells and subsequent desquamation of endothelium and neutrophil extracellular trap formation contribute to mechanisms of plaque erosion. Compared with ACS patients with plaque rupture, those with plaque erosion are younger, have ...

  Background: Effective and aesthetically appealing management options are needed for basal cell carcinoma (BCC), the most common skin cancer. The Nd:YAG laser shows promise, but most studies use biopsy to demonstrate tumor clearance. Optical coherence tomography (OCT) could allow good tumor margin control while enabling recurrence monitoring. Objective: Determine the efficacy of the Nd:YAG laser to treat BCCs while controlling for tumor margin with OCT. Methods: A 1064-nm ...

15. Confocal Microscopy and Anterior Segment Optical Coherence Tomography Imaging of the Ocular Surface and Bleb Morphology in Medically and Surgically Treated Glaucoma Patients: A Review
  
  Explore MDPI Open Access Journals Platform Jul 4 2021 Ophthalmology
  
  Glaucoma patients often suffer from ocular surface disease (OSD) caused by the chronic administration of topical anti-glaucoma medications, especially in cases of long-term therapy with preserved or multiple drugs. Additionally, glaucoma surgery may determine ocular surface changes related to the formation and location of the filtering bleb, the application of anti-mitotic agents, and the post-operative wound-healing processes within the conjunctiva. Recently, several studies have evaluated the role of advanced diagnostic ...

16. Three dimensional reconstruction of coronary artery stents from optical coherence tomography: experimental validation and clinical feasibility
  
  Explore Nature Publishing Group Jun 12 2021 Cardiology
  
  The structural morphology of coronary stents (e.g. stent expansion, lumen scaffolding, strut apposition, tissue protrusion, side branch jailing, strut fracture), and the local hemodynamic environment after stent deployment are key determinants of procedural success and subsequent clinical outcomes. High-resolution intracoronary imaging has the potential to enable the geometrically accurate three-dimensional (3D) reconstruction of coronary stents. The aim of this work was to present a novel algorithm for 3D stent ...
