WebDec 24, 2024 · The cranio-caudal and caudo-cranial CSF flow, velocity and stroke volume were measured at the C2 spinal level over one cardiac cycle using phase contrast MRI. Statistical analysis was performed to identify differences in CSF flow properties between the two positions. Results WebA common definition of Chiari I malformation is that one or both cerebellar tonsils are 5 mm or more below the basion-opisthion line as measured on a midline sagittal T1-weighted magnetic resonance imaging (MRI) scan [ 3 ]. Symptoms include occipital headaches, neck pain, disequilibrium, and gait disturbance.
