Abdominal 7T MRI is technically demanding, but has great potential due to the improved signal-to-noise-ratio and altered image contrast. We describe our initial experience of abdominal imaging on a 7T Terra scanner (Siemens), using an 8-channel TEM coil that was previously used on a Magnetom 7T scanner. First, we describe how we adapted the RF power limits from the VB17 format to the VE12U format, including an experimental validation. Then, we show our first human in vivo liver images from the 7T Terra, including B0 and B1+ maps, and FLASH images (radial and Cartesian), for two RF shim settings.
