In brief: A lot
Mri is superior. Utrasound reliable in total block or excellent flow but unable to determine degrees of stenosis.

I am afraid I have to disagree. MRI has a number of problems. Motion will ruin a study. MRI needs a lot of set up and hard to repeat if there is a failure. Claustrophobia, metallic implants, pacemakers and Kidney disease may preclude an exam. Resolution is better with U/S. It is easy to perform and less expensive. In good hands and with doppler, U/S may be more accurate than MRI.

In brief: Mostly technical
The carotid arteries are well seen on Carotid duplex scanning.
The problems are whether we can get good images of the arteries due to the patients anatomy. Sometimes thick necks and relative positon of the vessels make it hard to see them. The other issue is that when the carotid arteries enter the skull, they can no longer be seen on ultrasound.

In brief: Good screening test.
Cta best for imaging carotid arteries.
Mra can be used but often overestimates the amount of stenosis.
