I should also note that having an aneurysm doesn’t mean it will rupture. My Mom had high blood pressure & smoked a lot which her Dr. thinks contributed greatly to her rupture.
When I discussed my choice not to get an MRI with her, she understood why I felt that way and mentioned that my chances of a rupture would be a lot lower (if I had an aneurysm at all) since I don’t have high blood pressure or smoke.
