Synopsis

Keywords: Cancer, Whole BodyWater-Fat Imaging (WFI) based on chemical shifts can provide excellent separation of water and fat in tissue. This work investigated the application of WFI to spinal diseases. The diagnosis performances were compared with the T1-weighted (T1W) and T2-weighted short-TI-inversion-recovery (T2W STIR) sequence. For hyperosteogeny, spinal metastasis, and disc herniation, the WFI showed comparable performance as the combination of T1W and T2W STIR imaging within a much shorter acquisition time.
