A whole body (WB) MRI protocol added to a dedicated liver MRI in one scan session, could alleviate the need for a PET/CT for staging patients prior to local treatment of colorectal liver metastases. With the aim of developing a disease optimised WB protocol, 30 patients with extra-hepatic metastases from colorectal cancer were prospectively recruited and scanned on a 1.5 T scanner and using a PET/CT scan within an average of 1.33 days as reference. Preliminary results show that combining a traditional whole body MRI protocol with DWIBS produces superior results compared to the traditional protocol alone.
