MR angiography effective for diagnosing carotid artery stenosis
PRACTICE RECOMMENDATIONS

Magnetic resonance angiography (MRA) is better than duplex ultrasound for diagnosing severe (70%–99%) carotid artery stenosis. Both tests are highly accurate for diagnosing total carotid artery occlusion.

Whether this advantage translates into improved patient outcomes is not known. While cost was not addressed in this study, MRA is 2 to 3 times more expensive than duplex ultrasound.

If cost and effectiveness data support these results, then MRA and duplex ultrasound might replace digital subtraction angiography for carotid artery surgery selection.
