Coronary angiography had traditionally been used in our cardiac catheterisation laboratories in assessing the severity of coronary lesions, sizing the vessels and guiding the implantation of coronary stents. However, the information provided by angiography, being a luminogram only, is still limited, both for clinical and for research purposes. With the availability of intracoronary imaging techniques, direct information on plaque size and composition has provided additional information which is able to improve the guidance of interventional procedures and is an excellent intracoronary imaging tool for carrying out clinical research.
