Spatial-Spectral RF pulses have been widely adopted for many purposes, especially in the situation when fat-suppression is necessary. In this study, we utilized this idea to simultaneously generate fat-water separated imaging. For comparison, images with fat/water suppression were acquired using a conventional FLASH sequence. Our results showed these simultaneously acquired images have comparable contrast to the FLASH images. Consequently, our proposed method may be beneficial for studies that require dynamic information of both water and fat.
