MaryLou78, I can just imagine your concern about a fast growing aneurysm. So maybe this information will put your mind at rest until you see your cardio next visit. The Echo and the CT measure aortic aneurysms differently. One measures straight across and the other measures on a diagonal -- like the cut of penne pasta -- and the one measured on the diagonal will of course result in a higher number. I can't remember which is which. And then there is the margin of error resulting from different technicians running the testing. From what I understand, aneurysms grow rather slowly (mine has gone from 3.8 to 4.3 in 18 years). I'm sure your cardio has cautioned you against lifting more than a specified weight -- I am limited to 25 lbs. I wish you good luck. I remember how devastated I was to receive my diagnosis so I sympathize with you and I hope your cardio can put your mind at ease.
