Abstract		A clinical and epidemiological overview of abdominal aortic aneurysm (AAA) is presented together with risk factors for AAA developement, and the role of different imaging modalities in endovascular treatment is described. The role of abdominal uItrasound in detecting AAA and the role of digital subraction angiography in endovascular treatment is stressed. Role and criteria for computerized tomographic angiography (CTA) and magnetic resonance angiography (MRA) in confirmation of diagnosis of AAA, performance of endovascular treatment procedures, detection of complications and follow-up, are described. Also, protocols for CTA and MRA performance are supplied; before endovascular treatment and in follow-up with double scan depicting the arterial and late venouse phase. CTA is a widely accepted, fast and accurate imaging method for planning and follow-up of endovascular treatment. The negative influence of ionising radiation and iodinated contrast media, that may cause allergy and nephrotoxicity, is discussed. MRA gives the same information without the quoted negative effects, also metallic artefacts from the endoprosthesis are not a limitation of the method. Still, it is not widely accessible and the procedure takes longer than CTA. In newest reports, ultrasound with second generation contrast media gives information about aneurysmal sac expansion that could not be determined by CTA or MRA.
