Time-resoved volumetric acquisitions of the entire gastro-intestinal tract are crucial to understanding its function. To achieve sufficient temporal resolutions significant data undersampling is required. For this purpose L1 k-t SPIRiT was implemented in combination with a radial Golden angle stack of stars sampling pattern. Data acquired with an undersampling factor of 15 were obtained during a single breathhold in healthy subjects with good image quality.
