Acoustic radiation force impulse imaging for aneurysms

Date

Abstract
A method for reliable, noninvasive estimation of Abdominal Aortic Aneurysms (AAA) wall mechanics may be a useful clinical tool for rupture prediction. An in vitro AAA model was developed from an excised porcine aorta, with elastase treatment. The AAA model behaviour was analysed using Acoustic Radiation Force Impulse (ARFI) imaging techniques to generate displacements in both aneurysmal and normal aortic tissue. The incremental modulus of the arteries was indicative of early collagen recruitment, typical in aneurysms due to elastin degradation. Opening angle measurement showed a four fold decrease from healthy aorta to AAA model. The mechanical changes that occur during aneurysm formation were found to be detectable using ARFI imaging.
