Synopsis
In the human kidneys, the cortico-medullary sodium gradient plays an important role as it is essential for the concentration of urine and changes may indicate renal malfunction. However, quantitative 23Na MRI requires high-quality 1H MRI, since this facilitates co-registration and correction of partial volume effects, which is needed for body imaging in particular. We therefore show the feasibility of high-quality renal proton and sodium imaging using an 8Tx/16Rx 1H transceiver array that can be combined with a 23Na four-rung birdcage coil in a single setup.
