A method for predicting aneurysm growth based on CFD simulations derived from at least two angiography recordings is proposed. A first 3-D recording of the aneurysm is recorded at a first time and a first vascular geometry is determined for simulating a first CFD simulation. A second 3-D recording is recorded at a second time and a second vascular geometry is determined for simulating a second CFD simulation. The two 3-D recordings are registered and a local growth rate is determined from the two 3-D recordings. The local growth rate is correlated between the two vascular geometries with hemodynamically derived parameters from the first CFD simulation. A future vascular geometry and/or a future local growth rate is predicted based on the correlation parameters, the hemodynamic parameters from the second CFD simulation and the second vascular geometry.
