Identifying functionally significant intermediate coronary narrowings, characterizing plaque morphology, detecting moderate diffuse intimal thickening, evaluating the results of percutaneous coronary intervention (PCI), and assessing the status of the microvasculature all remain challenging with coronary angiography alone.1-6 Technologic advancements have made several adjunctive diagnostic techniques available that allow the interventional cardiologist to address the limitations of coronary angiography and more thoroughly assess the coronary circulation.
