Abstract

Purpose Advanced peripheral vascular ultrasound techniques, when combining high temporal and spatial resolution, infonnation intrinsic to the radiofrequency (RF) raw data, and simultaneous acquisition of physiological signals, have a potential to expand the range of clinical applications well beyond the currently used 2D and duplex/triplex imaging. Combining on-line computerized image and signals acquisitions and processing together with off-line capabilities of advanced analyses, allows to obtain detailed infonnation on vascular physiology and disease. This paper presents a short overview on some recent clinical applications and perspectives deriving from computer assisted methods applied to RF-based ultrasound. Estimate and characterization of atherosclerotic vascular disease from preclinical to advanced states, as well as novel approaches to noninvasive hemodynamics, will be briefly outlined. Methods RF-based automatic measurements are implemented in commercially available US systems for accurate estimate of common carotid intimamedia thickness (CCA-IMT), an established marker of preclinical vascular disease and predictor of risk in selected populations. It is potentially useful for improving risk stratification respect to estimates based upon conventional risk factors, which account per se about 50% only of the probability to develop a cardiovascular disease. Online arterial continuous tracking of arterial wall distension curves calibrated for blood pressure, together with contour wave analysis, yields not only indices of local arterial stiffness but also data on arterial wave reflection and LV ejection function.
