Strain imaging in abdominal aortic aneurysms using bistatic dual-aperture ultrasound.

ABSTRACT: Knowledge of the full geometry of abdominal aortic aneurysms (AAA) and local, mechanical wall parameters using ultrasound (US) can contribute to a better assessment of the AAA's mechanical state, prediction of growth and possible risk of rupture. Such an assessment is currently limited by the anisotropic lumen-wall contrast and the resolution of conventional US. The recent introduction of ultrafast dual-aperture imaging enhances image quality, using two transducers that alternately transmit and receive simultaneously ("bistatic" US). In this study, dual-aperture, bistatic US imaging is assessed in 43 AAA patients. Results were compared to single-aperture ultrafast imaging. Bistatic imaging was demonstrated successfully in 40 patients. Compared to single-aperture imaging, the median wall-lu
