OCT in BCC diagnosis

Abstract

Non-invasive diagnostic strategies, such as optical coherence tomography (OCT) enable detailed examination of skin tissue architecture and have potential for identification and subtyping of BCC. Optical coherence tomography (OCT) is an imaging technique that generates real-time in vivo cross-section images of tissue microarchitecture with a depth of 1.5-2 mm. OCT is based on light interferometry: the interference of two optical beams reflected by the tissue produces distinguishable shades in the black and white spectrum. Morphologic characteristics of BCC that may be distinguished on OCT images have been established in recent year
