In this study we measured the functional and morphological changes that occur during the formation and progression of atherosclerotic lesions in the abdominal aorta of ApoE-/- mice by the use of MR-Microscopy at 17.6T. The morphological changes were quantified by determining the mean arterial wall thickness. As functional parameter we assessed the local pulse wave velocity (PWV) which is an indicator for the arterial stiffness. Thereby we found, that the local PWV increases clearly before morphological changes are detectable, which makes the local PWV a very sensitive parameter for the examination of early stages of atherosclerosis.
