MR angiography for abdominal and thoracic aortic aneurysms: assessment before endovascular repair in patients with impaired renal function.

Objective: The aim of the study was to establish the feasibility of using MR angiography as the sole imaging technique before endovascular repair of abdominal or thoracic aortic aneurysms and to compare preprocedural measurements by MR angiography and digital subtraction angiography in patients with impaired renal function.

Conclusion: MR angiography appears to be effective and reliable for use as the sole imaging method before endovascular repair of aortic aneurysms in patients with renal impairment.
