Effects of free breathing on cerebrospinal fluid hydrodynamics: a study based on real-time phase-contrast MRI
Effets de la respiration libre sur l'hydrodynamique du liquide cérébro-spinal : une étude basée sur l'IRM de contraste de phase en temps réel
Résumé
Using real-time phase contrast MRI, the effect of free breathing on multiple parameters of CSF at the aqueduct and at the second-to-third cervical vertebrae were successfully quantified. During the expiratory phase, the amplitude, average stroke-volume and cardiac period of CSF increased. Synopsis The effect of breathing on CSF is not well understood. Real-time phase-contrast MRI can quantify CSF flow continuously. A time-domain multi-parameter analysis method was developed to quantify the effect of free breathing on CSF. It was found that the cardiac period and the average stroke volume of CSF at second-to-third cervical vertebrae level and at the aqueduct were significantly increased during the expiratory phase, while the net flow of CSF was notably decreased.
