The present study aims to explore feasibility of three-dimensional(3D)breath-hold(BH)magnetic resonance cholangiopancreatography (MRCP) through acceleration of the combination of compressed sensing and sensitivity encoding(CS-SENSE),and choose an optimal acceleration factor. 3D-MRCP scans on healthy volunteers were carried out with different acceleration factors (conventional SENSE factor of 4, and CS-SENSE factors of18, 24, and 32).The CS-SENSE acceleration factor of 24 was recommended because of the favorable image quality and reasonable scan duration (15s).
