Just after surgery there is a period were the remnant tissue needs to match the requirement of normal liver function while recovering. This could lead to fatal consequences after too extensive surgical procedures, or due to insufficient liver function. In contrast, it might also be the case that the surgical procedure is too conservative because the predicted liver function is underestimated. This would not have been the case if it was possible to use more precise measures of liver function. We investigated the capabilities of gadoxetate enhanced MRI for determining liver function pre- and post-surgery using two separate approaches.
