Cerebrospinal fluid (CSF) plays an important role in the clearance system of the brain. Recently, low b‐value diffusion tensor imaging (low‐b DTI) has been reported to be useful in the observation of CSF flow; however, the precise flow property observed by low‐b DTI has not been fully investigated. Accordingly, a mathematical framework of low‐b DTI is proposed for investigating CSF and clarifying its pseudorandom flow.
