Figure Lengend Snippet: Z-spectrum from the BSA phantom at 3T (dotted lines) and 7T (a). This Z-spectrum shows that the sample with Gd-DOTA does not exhibit CEST contrast at 2 ppm. Amine-CEST maps of the BSA phantoms at 3T (b) and 7T (c). CEST maps show a clear drop in contrast when combined with the Gd-DOTA contrast agent, both at 3T and 7T.
Article Snippet: BSA phantom MRI experiments were performed using a 3T whole body scanner (MAGNETOM Prisma, Siemens Healthcare, Erlangen, Germany) with a body transmit/32-channel receive proton phased-array head coil, as well as a 7T whole body scanner (MAGNETOM Terra, Siemens Healthcare, Erlangen, Germany) with a Nova Medical volume coil transmit/32-channel receive proton phased-array head coil, at 25 °C.
