Study Design
| Study Design Background | This study investigated the potential of 1H relaxometry and 23Na MRI to monitor water fluxes and dysregulation of Na+ homeostasis as novel target for therapeutic intervention. The effect of a forced Na+ influx induced by the ionophore monensin on hepatocellular carcinoma models was compared with that on hepatocytes and normal tissues |
