Intravascular ultrasound volumetric assessment of intimal hyperplasia in stents treated with intracoronary radiation

Abstract

Iridium-192 (gamma)-radiation is effective in preventing recurrent in-stent restenosis by reducing neointimal hyperplasia as illustrated by intravascular ultrasound study and plaque area-length plot. This analytic technique will further our understanding of vessel behavior to radiant energy source both inside and outside the stented coronary artery segments.
