The centric PE order is often preferable for bSSFP in physiological MR imaging to maximize signal contrast. However, the centric PE ordered bSSFP can cause artifacts due to eddy current and transient oscillation. Existing compensation schemes such as pairing or double averaging still have limitations in application for physiological MRI. In this study, we tested three new compensation schemes based on complex averaging of two datasets with different dummy scans or two datasets with different pairing schemes. The proposed schemes suppressed the eddy current and transient oscillation artifacts, while maintaining the temporal resolution the same as the original centric scheme.
