It has recently been shown that the WHO grade of a glioma is correlated with its electric conductivity, which can be determined via post-processing the acquired MR transceive phase. However, the transceive phase and thus the derived conductivity might be corrupted by motion induced phase, particularly from cardiac pulsation transferred to the cerebrospinal fluid (CSF). In this study, the impact of CSF pulsation on the reconstructed conductivity was investigated by synchronizing the transceive phase acquisition to the cardiac cycle. It turned out that the pulsation significantly affects reconstructed conductivity of the CSF, but not of gray and white matter.
