Improved computerized evaluation of abdominal aortic aneurysm

Accurate measurements of arterial anatomy are emerging as the most important determinants of endovascular abdominal aneurysm repair. It is quite difficult to define and measure arterial anatomy features quantitatively due to the complex structure of the aneurysm and insufficient visual feedback. During decision making, to assist operators in diagnosing abdominal aortic aneurysms, a specialized preprocessing Abdominal Aortic Aneurysm Measurement and Evaluation Tool (AMET) was developed. AMET provides visual interfaces with broad measurement capabilities to generate a 3D model of the aorta for a better diagnosis and accurate stent selection. The accuracy and usability of the tool was tested with a series of measurements that were carried out on a selected patient group. The obtained statistical results were evaluated and compared with the current applied method used by the radiodiagnostic department. Test results showed that the new introduced measurement and evaluation tool, AMET, has higher measurement quality compared to the conventional manual method
