Optimal treatment parameters of balloon angioplasty for revascularization such as inflation time and pressure are subject to debate. Limited data exists because accurate assessment of vascular function is challenging and therefore the influence procedure parameters have on arterial wall damage is largely unknown. This study shows that portable MRI at 0.125x0.125x2 mm³ resolution can be used for assessment of diameter and wall thickness during balloon angioplasty in ex vivo porcine arteries. Even after deflation and removal of the balloon the arterial diameter remained enlarged; this was coupled to a decrease in wall thickness.
