In this study, the Abdominal Aortic aneurysm is used as a model to show the ability of Zoom-accelerated Quadruple inversion Recovery to demonstrate post-contrast enhancement of the fibrous cap. The technique has been implemented here for cardiovascular imaging by adapting timing for ECG-gating. The advantage over traditional techniques is that exactly the same inversion times are used before and after contrast administration. This removes the implicit quantification bias of traditional sequences.
