"Quantitative assessment of the extent and severity of vascular disease"

Dr. Milan Sonka
Iowa Institute for Biomedical Imaging


Abstract

The presentation will focus on two main aspects of quantitative assessment of the extent and severity of vascular diseases: 1) screening for vascular disease presence and risk factors, and 2) assessment of disease severity in the presence of established vascular disease and plaque.

The talk will first discuss quantitative image-based approaches to assessing wall thickness (intima-media thickness or IMT) in carotid arteries using ultrasound and assessment of endothelial function in brachial arteries via flow mediated dilatation (or FMD) using ultrasound imaging. Both of these approaches are considered the earliest screening tests for cardiovascular disease and have a clear predictive value for development of heart attack and stroke. Quantitative image analysis solution will be presented that has become a de-facto standard for vascular ultrasound research studies worldwide.

Additional focus will be given to quantitative coronary image analysis via fusion of intravascular ultrasound (IVUS) and angiography, coronary plaque analysis, and plaque progression prediction based on IVUS-derived virtual histology. A summary of quantitative characteristics of coronary plaque morphology and tissue characterization will be presented.

The talk will be accompanied by live demonstrations of the software tools developed for the above-referenced purposes.
