Using the new 3D aMRI software, 4D animation models of brain motion can be created from an MRI image. The striking detail of these animated magnified movements may be able to help identify abnormalities, such as those caused by blockages of spinal fluids, which include blood and CSF (spinal fluid in the brain). 3D aMRI method outlined in Terem et al. Magnetic Resonance in Medicine (2021); Abderezaei et al. Brain Multi-physics (2021).
