Answer

OCT uses light-based imaging to capture micrometer-resolution images of the artery wall. It has 10 times higher resolution than IVUS does but is unable to penetrate as deep into the vessel wall. OCT’s high resolution enables it to better evaluate stent strut apposition and neointimal stent strut coverage.
