The ability to image sodium is believed to be a powerful tool to understand physiological processes, however have yet to be effectivity translated to clinical realistic usage. Through the use of an efficient k-space trajectory (3D cones) we have undertaken dynamic imaging of the renal sodium distribution pre and post- a furosemide injection. This work shows a decrease in the cortico-medullary sodium gradient over time, as well as being the first renal study on a clinical system with dynamic sodium imaging.
