Although it has been reported a method for monitoring the intraventricular cerebrospinal fluid (CSF) temperature calculated from the DWI, this method was affected by the CSF pulsation. We proposed the acceleration-motion compensation DWI (aMC-DWI) to the determination of the intraventricular temperature to improve that accuracy and precision. Compared with conventional DWI, measurement of intraventricular temperature using aMC-DWI was accuracy even in ventricles with high flow, e.g., third ventricle, fourth ventricle. These results suggested that aMC-DWI is a suitable method for analyzing the intraventricular temperature.
