OCT or Angiography Guidance for PCI in Complex Bifurcation Lesions

New England Journal of Medicine, 2023
BACKGROUND Imaging-guided percutaneous coronary intervention (PCI) is associated with better clinical outcomes than angiography-guided PCI. Whether routine optical coherence tomography (OCT) guidance in PCI of lesions involving coronary-artery branch ...

Role of AS-OCT in Managing Corneal Disorders

Diagnostics, 2022
Optical coherence tomography (OCT) is analogous to ultrasound biometry in the cross sectional imaging of ocular tissues. Development of current devices with deeper penetration and higher resolution has made it popular tool in clinics for visualization of

Corneal pachymetry by AS-OCT after Descemet’s membrane endothelial keratoplasty [PDF]

Scientific Reports, 2021
AbstractCorneal thickness (pachymetry) maps can be used to monitor restoration of corneal endothelial function, for example after Descemet’s membrane endothelial keratoplasty (DMEK). Automated delineation of the corneal interfaces in anterior segment optical coherence tomography (AS-OCT) can be challenging for corneas that are irregularly shaped due to
