Purpose: To evaluate whether in CE MRA of the supraaortic arteries the increased signal-to-noise (S/N) available at 3.0T would allow to replace the phased-array neurovascular coil by the quadrature body coil. Materials and Methods: In an ongoing, prospective study, 28 patients and 5 volunteers were examined on a commercially available 3.0T MR unit (Intera, Philips Medical Systems, Best, The Netherlands). CE-3D MR angiograms using CENTRA were acquired with the body coil using a FOV of 350mm that covered the supraaortic arteries up to the circle of Willis. The high image matrix of 432×432 over the 350mm FOV yielde…
