Thank you @upartist! Surprisingly my husband and I both have ascending aorta aneurysms. These are my measurements. I am usually the more optimistic about health concerns, but I am a little worried. I had seen a PA early on and he said that we could go over the scan results by phone since I live two hours away from their office. Less than two hours after the scan they called and arranged an appointment with the surgeon in a couple of weeks. So I am working to not worry. I imagine that the potential growth has just caught their attention and they will start taking a closer look. I found one mention in an article that implied .2cm might be in the margin of error.

Thank you for your support and advice. It helps!!
