This project involves a study of the diameter variation of abdominal aortic aneurysms (AAAs) over the cardiac cycle in vivo, a measure of the in vivo mechanical properties of AAA walls. Patient aneurysms are imaged non-invasively by ECG-gated MR Imaging, then mechanical properties of the aneurysms are determined from computational analysis of the imaging.
Inclusion Criteria
Patients:
- Presence of an abdominal aortic aneurysm.
Healthy volunteers:
Exclusion Criteria
Patients:
- Having already received surgical aneurysm repair,
- Psychologic difficulties preventing MR Imaging,
- Presence of metal implants preventing MR Imaging.
Healthy volunteers:
- Presence of an abdominal aortic aneurysm,
- Psychologic difficulties preventing MR Imaging,
- Presence of metal implants preventing MR Imaging.
Study Requirements
One visit to the MR Center, approximately 1/2 hour for one single MRI
