Evaluation of cerebrospinal flow at cerebral aqueduct by using magnetic resonance imaging technique
Main Article Content
Abstract
Background: Using cine phase –contrast magnetic resonance imaging to quantify the parameters of cerebrospinal
flow at the cerebral aqueduct.
Methods: Twenty patients with normal ventricule were performed with 1.5T magnetic resonance system (Avanto, Siemens). Using cine phase -contrast magnetic resonance imaging, put perpendicular at the cerebral aqueduct level. Phase, rephase and magnitude images were acquired. The parameters peak velocity, diastole volume, systole volume, net volume, average area were studied.
Results- Conclusion: There was a statistically significant difference in peak velocity between the age groups. There were no statistically significant differences in cranial and caudal volume, net volume and average area flow parameters among different age groups. Statistically significant differences were not detected in flow parameters between sexes.
