[Quantitative analysis of cerebrospinal fluid dynamics in syringomyelia using cine MRI with pre-saturation].
No To Shinkei. 1992 Jan; 44(1):24-9.NT

Abstract

Some reports show the qualitative analysis of cerebrospinal fluid (CSF) pulsation in the subarachnoid space and the syrinx using cine magnetic resonance imaging (MRI). However, few reports studied the quantitative analysis of CSF pulsation. We report here the results of quantitative analysis of CSF pulsation using the cine MRI with pre-saturation pulse. Using flow phantom, we calibrated the correlation between the true velocity and calculated velocity acquired from the movement of pre-saturated low signal. Three cases of syringomyelia with Chiari malformation, two cases of traumatic syringomyelia, and three normal volunteers were examined using this technique, and we could obtain time-velocity curves of CSF in both subarachnoid spaces and syrinx. Although obvious pulsation of CSF was observed in the syrinx of all Chiari malformations, no pulsation of CSF was observed in the syrinx of traumatic syringomyelia. CSF in the syrinx moves upward in the early systolic cardiac cycle, downward in the systolic cycle, and upward again in the diastolic cycle. Patterns of CSF pulsation in syrinx were similar to those in the subarachnoid space, but "phase" of these pulsations differed from case to case. These results suggest the close relationship between CSF pulsation in the syrinx and CSF obstruction at the cranio-vertebral junction. Dissociation of the "phase" of CSF pulsation in the syrinx and subarachnoid space may be significant in the analysis of the pathogenesis of syringomyelia.
