1. Advances in Intravascular Imaging

    This review updates the role of various intravascular imaging techniques (1) in the detection of vulnerable plaque and (2) during percutaneous coronary intervention (PCI), especially drug-eluting stent (DES) implantation and follow-up—including intravascular ultrasound (IVUS), virtual histology (VH-IVUS) and integrated backscatter (IB-IVUS), optical coherent tomography (OCT), near-infrared (NIR) spectroscopy, angioscopy, and MRI. IVUS, IB-IVUS, and VH-IVUS The current intracoronary ultrasound imaging frequency range of 20 to 45 MHz provides 70 to 200 µm axial resolution with >5 mm penetration.1,2 Grayscale IVUS allows robust quantitative measurements including lumen, vessel, and plaque area; qualitative assessment of lesions preintervention; and quantitative ...
