Zusammenfassung
Purpose: To provide a diffusion-weighted (DW) whole body MR imaging sequence with background body signal suppression (DWIBS) at 3.0 Tesla and to evaluate this sequence in first clinical applications. Material and Methods: A DW spin-echo echo-planar imaging sequence (60 transversal slices, 4mm thickness, FOV/RFOV=400/314mm, matrix 112×86, bmax=1000s/mm2 with NSA=6 and motion probing gradients in three orthogonal directions, SENSE factor 2, free breathing) was combined with the following methods of fat suppression: short TI inversion recovery (STIR), spectral attenuated inversion recovery (SPAIR), and spectral pre…
