Optical coherence tomography (OCT) - versus angiography-guided strategy for percutaneous coronary intervention: a meta-analysis of randomized trials

BMC Cardiovascular Disorders
Background Optical coherence tomography (OCT) guidance in percutaneous coronary intervention (PCI) has been shown to improve procedural outcomes. However, evidence supporting its superiority over angiography-guided PCI in terms of clinical outcomes is ...

OCT Angiography

Acta Ophthalmologica, 2017
SummaryOCT has become already a standard diagnostic tool in ophthalmology. Despite its continuous improvement in performance, its tissue specificity is still limited, as the contrast mechanism relies on local backscattering changes only. Functional extensions of OCT, in particular Doppler OCT and angiography partially mitigate this limitation.
