The intraventricular cerebrospinal fluid (CSF) temperature calculated from the diffusion coefficient is affected by the CSF pulsation. Therefore, we investigated the second-order motion compensation DTI (2nd-MC DTI) in consideration of fractional anisotropy (FA) for the CSF to the determination of the intraventricular temperature to improve that accuracy. The measurement of the intraventricular temperature with 2nd-MC DTI showed the least SD and can be more accurately estimated than conventional DTI.
