Understanding Aortic Measurement's

I had a echo done was told aortic root is 4.4cm I was told to get a CT with contrast and have the sinus of valsalva checked.

My report said this

The ascending aorta has a transverse dimension of 3.7 cm at the level

of the main pulmonary artery which is within normal limits. At the

sinotubular groove just above the coronary sinuses as measured in the

sagittal plane the aorta is 3.8 cm in diameter.

What does this mean? Do I need to request more measurements?
