Abstract: Elasticity imaging methods noninvasively generate images related to the viscoelastic moduli of tissues which are used clinically for disease diagnosis and to inform fundamental research studies. These methods mechanically perturb tissue, image the dynamic tissue response, and reconstruct images of the underlying tissue mechanical properties using material models of varying complexity. Acoustic radiation force (ARF) based ultrasonic elasticity imaging methods have become widely available commercially over the past decade, including both shearwave elasticity imaging (SWEI) and acoustic radiation force impulse imaging (ARFI) technologies, which provide quantitative (SWEI) and relative (ARFI) images of tissue elasticity.  To date, these methods have found success clinically in the context of hepatic fibrosis staging and lesion characterization in 2D implementations. The primary focus of our recent work has been the development and implementation of high resolution 3D ARFI and SWEI elasticity imaging methods, and the development and evaluation of multiparametric ultrasound imaging methods (mpUS) that combine concurrently acquired elasticity and backscatter information to enhance image contrast.   We are also developing 3D SWE tools employing higher order material models and advanced data acquisition and processing methods to better characterize anisotropic and dispersive materials. In this talk I will summarize our current findings and discuss the promise and some limitations of these methods.
