Flow studies are occasionally employed in patients with CMI. The tight foramen magnum is thought to cause disturbance in CSF flow dynamics, and there is evidence that this can be seen on flow-sensitive phase contrast MRI sequences [14]. There is evidence that this CSF flow disturbance may be causally related to the formation of the syringomyelia [15]. Some authors have used this modality to determine the need for surgery and to measure the success of their surgical treatment [16]. Overall, it is not a critical study and generally does not add more information than the clinical symptomatology.
