What is 3D gadolinium-enhanced MR angiography of the carotid arteries about?

## Purpose: To compare gadolinium-enhanced magnetic resonance angiography (mra) of the carotid bifurcation with 2d time-of-flight (tof) mr angiography with regard to image quality and duration of examination. ## Materials and methods: Gadolinium contrast was administered intravenously during 3d mr imaging at 1.5 tesla in 46 patients presenting with suspected carotid occlusive disease. 2d time-of-flight mr angiography of the carotid bifurcation had been performed in each patient prior to gadolinium-enhanced mr angiography. ## Results: Gadolinium mra eliminated slice misregistration and in-plane saturation artifacts that occasionally degrades 2d tof mr angiography. gadolinium mra required less than 4 min to image from the aortic arch to the skull base compared to 11 min for 2d tof with comparable signal-to-noise ratio (snr). postprocessing was required to eliminate overlapping venous enhancement. both techniques had susceptibility related artifactual loss of signal at the skull base and both demonstrated a linear artifact paralleling the long axis of arteries. ## Conclusion: Gadolinium-enhanced mr angiography is a promising technique for the evaluation of patients with carotid occlus
