title: [Intravascular imaging and its integration into coronary angiography].
abstract: Despite technical innovations of non-invasive coronary imaging modalities,                     coronary angiography still remains the standard of reference for the assessment                     of CAD.The advances in interventional cardiology require also increased imaging                     capabilities, which cannot be fully addressed by conventional coronary                     angiography. Intravascular ultrasound (IVUS) and optical coherence tomography                     (OCT) as well as near infrared spectroscopy (NIRS) are important developments                     and will be covered in this review article.IVUS was already around in interventional cardiology since the 90ies. It was the                     first to offer a high resolution tomographic image of the coronary arteries in                     vivo. Beyond that, it is also frequently used for peri- and postprocedural                     imaging. Furthermore, the radiofrequency information ("virtual histology") can                     be applied to perform a basic tissue characterization.Using near coherent light instead of ultrasound, optical coherence tomography                     (OCT) is able to deliver a 10 fold higher resolution compared to IVUS when                     imaging coronary plaques.This allows also for the detection of potential vulnerable lesions as well as for                     the detection of neo-intimal stent strut coverage following stent placement.Using near infrared spectroscopy (NIRS) even insights into the chemical                     composition of coronary plaques can be achieved.The development of advanced image acquisition technologies enables us to combine                     modern intravascular imaging technologies and conventional coronary angiography                     and hereby achieve additional benefit.
