Study on imaging parameters in CSF flow rate measurement method using Phase-Contrast.

Not Applicable

• Conditions: Cervical myelopathy Arnold-Chiari malformation

• Registration Number: JPRN-UMIN000009681
• Lead Sponsor: Saitama Medical Center

Brief Summary

That from the measurement data of a healthy person, it is a constant velocity encoding because there is a difference in the individual is difficult. However, high correlation of CSF flow rate was observed in the sagittal and horizontal cross-section is the same between the wise man. Therefore, it was decided that velocity encoding checked whether the flow velocity in the sagittal, and performs each set in the horizontal cross-sectional. I suspect about 6 to 15 is suitable to velocity encoding of CSF measurement.
