Carotid and aortic sodium MR images were acquired from four healthy volunteers, using a 3D cones trajectory and a birdcage sodium transmit/receive coil. Vascular structures such as the carotid bifurcation and aortic arch were observed in the sodium images. T1 maps were estimated via the variable flip angle fitting method. B1 maps were estimated with the dual angle method. Sodium concentration was estimated using a linear model with two fiducials as the reference. The results show sodium MR imaging can provide non-invasive and quantitative measurements of the sodium concentration near possible locations of vascular diseases.
