Echo-planer imaging-based three-dimensional cine phase contrast (4D flow) MRI has been reported to achieve good image quality with a short acquisition time in cardiovascular imaging, but its application to the portal venous (PV) system has not been reported. In this study, the turbo-field echo-planar imaging (TFEPI) 4D flow MRI with a turbo-field echo (TFE)-based one in the PV system was compared. The TFEPI sequence showed a better image quality and flow consistency at the splenic and superior mesenteric vein confluence with a shorter acquisition time compared to the conventional TFE-based one.
