Traditionally, the normal refererence range for the aortic root diamater is between 2.0-3.7 cm. Your MRI report would suggest that there is some dilation of your Ao root. As this MRI was ordered for some reason, I would be sure to discuss these findings with your physician at your follow-up appointment.
Q:Aortic root at Sinus of vasalva 4.7cm
>>>>>By conventional measurements your aortic root is dilated. If and when the aorta root is >4 cm, it is medically termed an aneurysm and should be closely watched. If the diameter size increases to >5.0 and/or grows more than 0.5 cm in year, the need for intervention my be considered to prevent a rupture. Do you have a previous reading of the root?
Thanks for your question, and if you have any further questions or comments you are welcome to respond. Take care,
