A subject‐specific assessment of measurement errors and their correction in cerebrospinal fluid velocity maps using 4D flow MRI

Purpose Phase‐contrast MRI (PC‐MRI) of cerebrospinal fluid (CSF) velocity is used to evaluate the characteristics of intracranial diseases, such as normal‐pressure hydrocephalus (NPH). Nevertheless, PC‐MRI has several potential error sources, with eddy‐current‐based phase offset error being non‐negl...
