Yes, your doctor will tell you where the aneurysm is suspected and CT, MRI, or Angiograms will be chosen to find the size, location, etc., or, if you don’t have it, it could be something else.

It depends on where the aneurysm is located. If the aneurysm is suspected to be the abdominal aorta, then this is easy to screen using ultrasound. The first question would be know suspected location of the aneurysm before deciding on the modality.
