Multi-Station Multi-Sequence Approach for Whole-Body Diffusion-Weighted Imaging

Yeji Han¹, Sandra Huff¹, Jrgen Hennig¹, Ute Ludwig¹

Recent report on wbDWI shows images acquired with body coils because surface coils result in significant respiratory artifact and the patients have to suffer from the weights of the surface coils. However, surface coils can generate better images for certain regions. Thus, we propose a method to employ the advantages of both the body and the surface coils to effectively obtain wbDWI using multi-station approach. In order to shorten the imaging time with body coils, an EPI reconstruction method is also proposed. The proposed method together with STIR-DWEPI sequence should produce good quality images with sufficiently suppressed fat signals.
