A member asked:

My mother recently had ultrasound on carotid that showed 60 80% blockage but mra showed minimal why the vastly different results?

A doctor has provided 1 answer

US vs MRA: MRA is more precise, and more accurate. Ultrasound is a reflection of sound waves. It is blurry. MRA is precise.

Dr Fowler and 4 doctors agreed
