The aim of the study was to analyze the use and indication of 3 imaging modalities (CT, DSA and MRI) for patients with suspicion of aortic aneurysm. During 18 months 383 patients with suspicion of aortic aneurysm were examined with CT (SCT/MSCT), 17 with digital subtraction angiography (DSA), and 15 with MRI. Diagnostic DSA was performed in 7 cases for planning endoluminal therapy, in 7 cases because of unclear findings in CT and in 4 cases because of dissection of the aorta. MRI was performed in 12 cases with previously performed CT and in 3 cases as the only imaging modality because of intolerance to iodinated contrast material. CT is a well established and in most cases sufficient method for the examination of patients with the suspicion of aortic aneurysm. CT is widely available, and provides good image quality and a high diagnostic accuracy. Additional examinations with DSA or MRI are necessary in less than 5% of the patients.
