Local tumour staging CT and/or MRI of the liver, to evaluate Number and location of CRLM Tumour-vessels relationship Pattern of the hepatic vasculature Presence of anatomical variations Future remnant liver volumes

Intraoperative assessment Intraoperative ultrasonography

Evaluation of metastatic disease CT of the chest, abdomen, and pelvis MRI of the chest, abdomen, and pelvis, in selected cases 18FDG-PET–CT
