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.
