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.
