Computer simulation helps predict cerebral aneurysms

Researchers have recently proven the ability of computer simulation to predict the behaviour of cerebral aneurysms. Accurately simulating the flow of blood within the aneurysm helps researchers to predict the growth pattern of the aneurysm and the danger of rupturing. As this tool is further developed into a practical diagnostic tool, it is expected to dramatically improve the ability of surgeons to weigh the results of alternate treatment methods. The simulation method used, computational fluid dynamics (CFD), provides much more information than current diagnostic tools, including particularly sheer stress levels at various stages of the cardiac cycle, which help to pinpoint areas of aneurysm formation and growth.
