Aneurisk is a scientific project developed in Italy from 2005 through 2008, supported by SIEMENS Medical Solutions, Italy with the collaboration of Fondazione Politecnico di Milano, Mario Negri Institute for Pharmacological Research, Bergamo, Ca' Granda Hospital, Niguarda, Milano. The project was developed in the Laboratory MOX (Modeling and Scientific Computing) of the Department of Mathematics of Politecnico di Milano, under the direction of Alessandro Veneziani (currently with the Department of Mathematics and Computer Science of Emory University). The aim of the project was to perform an extensive statistical analysis of the geometry and hemodynamics of vessels hosting a cerebral aneurysm to identify possible correlations with rupture. From DICOM images of 3D rotational angiographies, semi-automatic tools have been developed for accurate reconstruction and characterization of the geometries; these geometries have then been used for simulations of blood dynamics; finally, the integrated data (morphology + hemodynamics) have been analyzed with a principal component analysis and a quadratic discriminant analysis to correlate predictive landmarks for rupture.
The project has been then followed up with the support of the Brain Aneurysm Foundation in the USA and the Emory University Research Committee 2011-2012, whose support for the creation of the present website is gratefully acknowledged.
This website collects the data retrieved during the Project in searchable and downloadable form. In particular, it hosts DICOM images, 3D reconstructions and geometric characterizations, numerical simulations of all cases in the Aneurisk data set.
We firmly believe that sharing the data will provide the opportunity to compare results, perform validation and eventually improve the understanding and the therapy of cerebral aneurysms.
