Types of Optical Coherence Tomography for Cancer Diagnosis: A Systematic Review

Optical coherence tomography (OCT) is an emerging imaging technique that produces high contrast images that help distinguish different tissue layers by detecting the back-reflected near-infrared light. The technique is used to diagnose various diseases due to high contrast, three-dimensional imaging capability with high resolution, and a fast acquisition speed. The meta-analysis study was performed by the systematic review of literature in PubMed, Web of Science, Scopus, Google Scholar, Embase, and Cochrane Library using search terms relevant to “OCT”, "Carcinoma", and “cancers”. The various applications of different types of OCT are discussed in the detection and diagnosis of various cancers like colorectal cancer, breast cancer, skin cancer, brain cancer, prostate cancer, ovarian cancer and lung cancer.
