A change in elastin and collagen content is indicative of damage caused by hypertension, which changes the non-linear behavior of the vessel wall. This study was aimed at investigating the feasibility of monitoring the non-linear material behavior in an angiotensin II hypertensive mice model. Aortas from 13 hypertensive mice were imaged with pulse wave imaging (PWI) over 4 wk using a 40-MHz linear array. The pulse wave velocity was estimated using two wave features: (i) the maximum axial acceleration of the foot (PWVdia) and (ii) the maximum axial acceleration of the dicrotic notch (). The Bramwell-Hill equation was used to derive the compliance at diastolic and end-systolic pressure. This study demonstrated the potential of PWI in a hypertensive mouse model to image and quantify the non-linear material behavior in-vivo. End-systolic compliance could differentiate between the sham and Ang-II group whereas the diastolic compliance could not, indicating that PWI can detect early collagen-dominated remodeling.
