CT Angiogram – This shows the anatomy of the arterial tree and the aneurysmal dilatation though the size is better seen on ultrasound because of clots in the aneurysmal wall.
MRI screening – This is also a painless screening test. It contains a large magnet encircling a table on which the patient lies and this table slides into the tunnel. The magnetic field aligns atomic particles in some of your cells. When radio waves are broadcast toward these aligned particles they produce signals that vary according to the tissue they are. The images produced by these signals show if there is an aneurysm.
