Single-shot water/fat separation T2* mapping with multiple overlapping-echo detachment imaging

Most of the water/fat separation techniques need to acquire multiple images with different echo time, which usually take long acquisition time. Multiple overlapping-echo detachment (MOLED) imaging can shorten acquisition time by acquiring multiple MR echo signals in the same k-space. Here, a new method for fast water/fat separation T2* mapping with MOLED technology was proposed, which can obtain quantitative T2* maps and M0 maps of water and fat in a single shot. In vivo experiment demonstrates that the proposed method can obtain accurate quantitative parameter values and accurate separation of water and fat images.
