Quantitative susceptibility mapping (QSM) has recently been in the limelight as a novel contrast mechanism to provide quantification of apparent magnetic susceptibility based on phase information in MR images. In this study, we explore feasibility of single point imaging (SPI) for QSM. SPI, also known as constant time encoding or pure phase encoding, provides true phase information not affected by phase evolution during readout, which is beneficial for accurate QSM. We propose a new and efficient SPI acquisition scheme for QSM, termed Continuous SPI, where SPI images are continuously obtained with extremely high temporal resolution in a single scan.
