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.
