In-vivo mechanical characterization of abdominal aortic aneurysms and healthy aortas using 4D ultrasound:a comparison study

Abstract

\u3cp\u3eAbdominal aortic aneurysms are lethal in 80% of all cases when ruptured. Current guidelines for AAA repair are mainly based on the diameter, which has its shortcomings. Hence, a more patient-specific rupture risk assessment is needed. In this study, methods for elastography and wall stress analysis using 4D ultrasound (US) were developed. Patient-specific material properties and peak wall stresses were compared between young and age-matched volunteers, and AAA patients.\u3c/p\u3
