Up to now only a few 23Na abdominal MRI studies have been performed at 7T. In this work, a versatile 23Na transceive elliptical-shaped body coil for 7T with a large FOV and a high transmit/receive efficiency was designed, simulated, and implemented on a 7T scanner. The setup was applied for in-vivo imaging of the human torso. The obtained 3D 23Na image data set contains 23Na signals from heart to pelvis. High regional 23Na signals are especially present in the areas of kidney, liver, cartilage, vessels, vertebral disks, spinal canal, and heart.
