Abstract

Hemodynamic parameters based on the temporal behavior of contrast agent flow in cerebral aneurysms represent important indicators of the effectiveness of deployed micro devices. These measurements are also interesting for the assessment of virtual treatment planning strategies such as virtual device implantation combined with CFD simulations of blood flow and subsequently generated synthetic angiograms (virtual angiography). Due to settlement effects, contrast agent residence time may increase. As of today, virtual angiography does not explicitly model these effects such that differences between real and virtual angiograms are existent. Hence, we present an approach to examine this contrast agent settlement in virtual angiograms by adding a gravitational effect on simulated contrast agent. The model is evaluated on several cases with different characteristics by generating virtual angiograms with and without the proposed gravity model and comparisons against acquired, real angiograms. Primarily with regards to wash-out behavior and residence time, virtual angiograms including a gravity component show a significantly improved concordance with acquired angiograms.
