The treatment of aortic aneurysms is today based on different indicators (diameters, lengths, angles, volumes of the arteries) measured on CT scan images. Several indicators are time consuming and complicatated to measure. They demand training and practice. Nurea is developing a software for automatic measurement of these indicators, PRAEVAorta® 2, to facilitate and assist the physician in his clinical routine. The purpose of this study is to compare the analysis realised by the software PRAEVAorta® 2 with the analysis realised by the healthcare professional on retrospective CT scan images. Contrasted and non-contrasted, pre-operation or post-operation CT scans from 50 patients will be analysed. The main objectif is to validate the accuracy of the software by demonstrating its adequacy to the standard method of analysis. The second objectives are the following: * Evaluate the security of the software PRAEVAorta® 2 * Evaluate the unanticipated risks related to the use of the software * Validate the accessory PRAEVAorta® Web We make the following assumption : 90% of the patients show 90% of adequacy to the healthcare professional analysis
