The complexity of the human cerebral ventricular system, coupled with its deep position within the brain, may pose a problem for conceptualizing its anatomy. Cadaveric dissection may be inadequate for learning the anatomy of the cerebral ventricular system as ventricular structures represent spaces rather than physical structures. Three‐dimensional (3D) computer reconstruction of the ventricular system may offer a solution. This study aims to create an accurate 3D computer reconstruction of the ventricular system with surrounding structures from 4T magnetic resonance (MR) scans of a male cadaver. Using 3D segmentation and rendering software, structures of interest were reconstructed through manual segmentation. The finished model can be manipulated by adding or removing structures, altering opacity, or taking slices through the model to highlight inner structures. Complex physiologic concepts, such as cerebrospinal fluid flow, can be shown using the 3D model through a video animation. Stereoscopic projection can be used increase depth perception and emphasize spatial relationships between anatomical structures. This model is suited for both self‐directed learning and classroom teaching of 3D anatomical structure and spatial orientation of the ventricles, their connections, and their relation to adjacent neural and skeletal structures.
