Ultrasonography and contrast-enhanced MRA in ICA-stenosis: is conventional angiography obsolete?
BACKGROUND: The standard techniques for the screening and staging of internal carotid artery (ICA) stenosis are Doppler (continuous wave) and Duplex sonography. For the imaging of ICA occlusive disease, magnetic resonance angiography (MRA) is replacing digital subtraction angiography (DSA). The purpose of this observational study was to assess whether contrast enhanced MRA (CE-MRA) combined with ultrasound provided sufficient information for the planning of surgical treatment. METHODS: CE-MRA...Expand abstract
