INTRAVASCULAR ULTRASOUND:

Cardiology Clinics, 1997
IVUS provides a new gold standard for visualization and measurement of coronary artery disease. Morphologic and morphometric observations by IVUS are in general considerably more detailed and accurate than those obtained by angiography. IVUS has led to new insights into the pathophysiology of coronary plaque accumulation with respect to adaptive vessel
