With the recent introduction of hybrid modalities such
as PET/MR, whole-body MRI reinforces its importance in
the staging and follow-up of oncologic patients. A
typical whole-body MRI exam contains T2w and T1w
sequences as well as diffusion-weighted imaging with
background suppression (DWIBS). We propose a flexible
whole-body MR protocol using an interleaved
multi-station approach where T1w and T2w sequences are
acquired during the same breath-hold and DWIBS during
free-breathing. This allows reduced number of
breath-holds asked to the patient and guarantee perfect
registration of images to facilitate for optimal
clinical diagnosis and to support proper attenuation
correction for the PET.
