Measuring assending Aortic aneurysm length
What do they use to measure the length, and how do you know if it's bad ?
I have a 46mm and that's the only measurement I find. They did a high resolution ct. I would have thought it could be measured,but maybe not. They also defined mine as dilated and not an aneurysm, I've seen that discussed a couple times, but really unclear on the difference. You would think 46 would be big enough to be called an aneurysm.

I have had multiple CTs the past four years. Not once has the tech reading the images highlighted the length. The Dr. I am seeing at Montefiore Medical in the Bronx is the only one who has brought up the length. My length is around 11.5 cm. He also looks at the ratio of the diameter of the ascending aortic value vs the diameter of the descending aortic valve. He has shared with me recent research (published within the past year) that suggests length is a stronger determinant of the risk of dissection than the width which is what almost everyone focuses on. It seems the magic number for surgery for most surgeons (absent other possible risk factors) is an aneurysm of 5.5 cm or growth > 0.5 cm in one year. Frankly, you can go to five different doctors and receive five different answers and also receive five different measurements.
I can’t answer the difference between dilated and an aneurysm

I have 3 images with measurements... one is the 46 width, one is 35 pulminary trunk, and the last one is 13, but don't know what it is.
Sorry, I can’t help you there.
