Thermochemical ablation (TCA) is a novel minimally invasive ablation approach. Acetic acid and sodium hydroxide are injected simultaneously and mix and react directly before entering the tissue. The exothermal reaction releases heat that is used for thermal ablation. For a detailed characterization of TCA injection, 4D 23Na-data with reasonable temporal resolution are required. In this work, a compressed sensing approach was applied to acquire 4D 23Na-data of injections with high spatial and good temporal resolution.
