Analysis of Spinal CSF-Flow Phenomena with an MR Cine Mode Using Fast Sequences. Demonstration by MR-Movie
Spinal CSF flow had formerly been difficult to analyse. It is pulsatile, highly dependent on the heart cycle, changes direction and magnitude rapidly and it could only be studied invasively (duBoulay 1966). The ability of MR imaging in demonstrating flow phenomena is well known. Gradient echo imaging provides a new MRI method for the noninvasive study of fast, pulsatile flow, since data acquisition can be triggered by the R-wave and is very fast (Frahm et al. 1987), providing a time resolution down to less than 30 msec (MR-cine mode).
