简介：
Overview
This article presents a standardized protocol for the manual segmentation of the choroid plexus within the lateral third and fourth ventricles of the brain. The need for this protocol arises from the complexity of the choroid plexus's location and the scarcity of reliable automated segmentation tools in neuroimaging studies. The protocol aims to produce a dataset to train algorithms for accurate automatic segmentation, which is crucial for future studies on neurologic and neuropsychiatric disorders.
