A free-breathing 3D cine SSFP technique was developed using the Z Intensity weighted Position (ZIP) which is the center of mass of a projection along the slice direction as a respiratory gating signal. The ZIP signal was continuously acquired using a slice encoded k-space center sampling in every TR. The performance of this gating method was compared with a method using the k-space center signal (KC) and with conventional 2D breath-hold cine SSFP in healthy subjects by measuring image quality and left-ventricular function. The preliminary data obtained here demonstrated that the ZIP gating method provided superior respiratory motion artifact suppression when compared to the KC gating and provided left-ventricular ejection fractions, end-diastolic and end-systolic volumes similar to those obtained with the breath-hold 2D cine SSFP acquisition.
