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.
