Study to Evaluate Cerebral AneurysmFlow Results in Occlusion

AneurysmFlow R1.0 is an approved (CE labeled, cleared in US, Canada and Argentina), software tool intended to provide relevant information on the blood flow in a cerebral aneurysm and its parent artery based on angiography. It provides color coded and vector field representation of a digital subtraction angiography (DSA). It can quantify blood flow rates in the artery based on DSA and 3-D Rotational Angiogram (3DRA) data. It can visualize blood flow patterns in an aneurysm based on DSA data. Specifically, it calculates the Mean Aneurysm Flow Amplitude (MAFA) ratio to measure the volumetric flow rate quotient before and after Flow Diverter Stent (FDS) implantation in the region of interest. It is manufactured by Philips Medical Systems B.V., a Philips Healthcare company.
