Combined sonography and magnetic resonance angiography (MRA) beat carotid catheterisation

Magnetic resonance angiography (MRA) and duplex sonography should replace catheterisation for carotid artery assessment. When the two non-invasive techniques are combined they are safer and more cost-effective, says a study in JAMA (September 20th). Researchers from the Beth Israel and Brigham & Women's Hospitals (US) assessed four pre-surgical evaluation techniques for patients at high risk of carotid artery disease: duplex sonograpy, MRA, catheterisation, and combined sonography and MRA. The dual screening technique (with catheterisation as a back-up) resulted in fewer complications, a lower death rate and was less expensive than catheterisation alone.
