A randomized controlled trial comparing CT chest/abdomen and liver-MRI versus CT chest/abdomen would neither be efficient nor practical. Any beneficial effect on patient outcomes would only be observed in those with additional CS-CRLM on MRI; the existence and size of that subgroup is the main target of this accuracy study. In addition, routine liver-MRI is already integrated in daily practice in many centers. Within the study design proposed here, liver-MRI will not be withheld from any patient. Sample size calculation indicate that 298 patients will have to be included to obtain estimates of change in management of 10% with 95% confidence intervals (CIs) that do not exceed 7% (95%CIs: 6.5%-13.5%). We plan to recruit these patients during a 16-month period. Only patients who are considered candidates for curative surgery (+/- per-operative ablation) based on CT findings are eligible. First, based on the CT findings, the liver surgery plan (+/- per-operative ablation) will be documented. Thereafter, findings at MRI will be discussed.
