The present study investigates the clinical utility of motion-insensitive breath-hold 3D MRCP using contrast-enhanced timing robust acquisition order with a preparation of the longitudinal signal component(CENTRA-Plus). 3D MRCP image derived from breath0holding with CENTRA-Plus showed good correlations to those from conventional respiratory triggering technique. Breath hold 3D MRCP with CENTRA-Plus can reduce scan time (around 80% of the scan time) without any penalty for the image quality; therefore, it might contribute to great advantages in routine clinical work.
