Ultrasound elastography of abdominal aortic aneurysms

Non-invasive assessment of the E-modulus in vivo distinguishes patients from normals (I). The 2D US results are in good correspondence with MRI (II) but seem low compared to 3D US (III). A next step will be combining 3D geometry, motion and material properties into patient-specific FE models. Stress-strain measurements yield elastin and collagen properties (IV). The latter might enable growth prediction based on elastin degradation or collagen deposition in the future.
