DISCO (Differential Subsampling with Cartesian Ordering) is high spatial-temporal imaging technique with Dixon based fat suppression for 3D volumetric Abdominal imaging. We developed DISCO with frequency selective presaturation pulse for fat suppression (FatSAT) called FatSAT DISCO. The feasibility study explores the computational advantage of FatSAT DISCO in accelerating scan time with compressed sensing technique and demonstrated that it is a promising technique for achieving faster imaging for 4D dynamic MR imaging with robustness to image artifact and light computation demand for clinical use.
