Honeycomb or Lotus Root-Like Intracoronary Pattern: Insights From Optical Coherence Tomography of a Recanalized Thrombus. [PDF]

Catheter Cardiovasc Interv
ABSTRACT Spontaneous recanalized coronary thrombus (SRCT) has been identified in autopsy studies as multiple interconnected channels separated by thin septa. Despite its potential clinical significance, SRCT remains underdiagnosed. Recent advances in intracoronary imaging, including optical coherence tomography (OCT), have elucidated its ...

Use of Optical Coherence Tomography in Dentistry

International Journal of Dentistry, Volume 2023, Issue 1, 2023., 2023
Optical coherence tomography (OCT) is an optics‐based imaging technique, which may be called an “optical biopsy.” It can be used to acquire structural information about a tissue at a resolution comparable to histopathology. OCT is based on the principle of low‐coherence interferometry where near‐infrared (NIR) light is shown on a tissue sample and then

Exploiting molecular probes to perform near‐infrared fluorescence‐guided surgery

VIEW, Volume 1, Issue 4, December 2020., 2020
Near‐infrared (NIR) fluorescence imaging can provide real‐time navigation for surgeons to discriminate boundaries between lesions and healthy tissue, which serves as a promising tool to enhance precise diagnosis and accurate excision during surgery. Although a great quantity of fluorescent probes has been employed in clinical trials, the U.S.

Optical imaging techniques for vulnerable plaque detection

Translational Biophotonics, Volume 2, Issue 3, August 2020., 2020
Vulnerable plaque rupture is the most important cause of myocardial infarction and acute coronary syndrome. Therefore, identifying vulnerable plaques is of prime importance, which will in turn aid in the development of treatments to stabilise them. This review article gives a brief understanding about the current optical imaging techniques used to ...

Neoatherosclerosis after Drug‐Eluting Stent Implantation: Roles and Mechanisms

Oxidative Medicine and Cellular Longevity, Volume 2016, Issue 1, 2016., 2016
In‐stent neoatherosclerosis (NA), characterized by a relatively thin fibrous cap and large volume of yellow‐lipid accumulation after drug‐eluting stents (DES) implantation, has attracted much attention owing to its close relationship with late complications, such as revascularization and late stent thrombosis (ST).
