Supports combined duplex sonography-MRA as potentially cost-effective for carotid stenosis evaluation; leaves open prospective validation in contemporary cohorts.
Is the combination of duplex sonography and MRA cost-effective compared to other imaging strategies for the preoperative evaluation of symptomatic patients with 70-99% carotid stenosis?
For preoperative detection of 70-99% carotid stenosis, combining duplex sonography and MRA is associated with the lowest long-term morbidity and mortality and has a favorable cost-effectiveness ratio.
