Scan time consideration and large FOV requirement for whole body (WB) imaging have precluded most previous WBMRI approaches from acquiring images with a large number of sequences and in different imaging planes. This can seriously affect reading confidence and lower diagnostic accuracy. In this study, we propose to use two fast Dixon sequences and a STIR-prepared diffusion weighted sequence for WB imaging. In 24 cancer patients, we demonstrate that a complete WBMRI including T2-weighted, T1-weighted (pre and post contrast injection), and diffusion-weighted imaging can be performed within approximately 1-hour on a commercially available 1.5 Tesla scanner.
