Lanthanide-HPDO3A chelates are stable and safe compounds, some of which apt for contrast agent mediated ParaCEST imaging. In this work we observe some promising candidates for functional CEST ratiometrical analyses and determine their suitability for studies at 1T field strength. An in vivo proof of concept study was performed to further investigate this methodology. The use of entry level MRI instrumentation will expand the scope of ParaCEST techniques.
