Magnetic resonance imaging as a tool to assess reliability in simulating hemodynamics in cerebral aneurysms with a dedicated computational fluid dynamics prototype: preliminary results

The concept of using medical image data for the creation of computational models and the subsequent simulation of hemodynamics in these models has been expressed already almost 20 years ago (1,2). Around a decade ago, this concept was revived mainly because of the progress in computational hardware which enables the researcher to now conduct these simulations on personal computer workstation with cost-effective, versatile software that is flexible enough to be used with computational models derived from medical image data for a specific patient (3). Since then, a variety of studies have been published exploring the feasibility of using computational fluid dynamics (CFD) for the simulation and quantification of aneurysm hemodynamics as well as investigating its usefulness for therapeutic applications
