What is it about?
Time-spatial labeling inversion pulse (Time-SLIP) MRI is a recently developed technique that can provide useful information of CSF dynamics in a non-invasive manner. In the present study, we emphasized that the comprehensive detection of ventral and dorsal combined CSF motion at the craniocervical junction would help us decide the necessity of craniocervical decompression in patients with Chiari malformation type I.

Why is it important?
Time-SLIP MRI can provide a qualitative evaluation of CSF flow, such as the range of CSF motion over more than 4 s. In the present study, we measured labeled CSF movement at the craniocervical junction (CCJ) preoperatively and/or postoperatively by Time-SLIP MRI to investigate whether the data become a useful index for the assessment of CSF flow disturbance in Chiari malformation type I (CM-I). Consequently, we emphasize that the comprehensive detection of ventral and dorsal combined CSF motion at CCJ, in addition to conventional static findings such as the identification of a syrinx, would help us decide the necessity of craniocervical decompression in patients with CM-I.
Perspectives
Time-SLIP MRI enabled clinicians to use novel dynamic indices, such as CSF motions at the CCJ, thus helping them in deciding craniocervical decompression with or without duraplasty in patients with CM-I. In particular, it was essential to examine the combined ventral and dorsal CSF dynamics in assessing CSF patency at CCJ.
