The effect of respiration on CSF movement was
investigated using a non-contrast time-spatial labeling
inversion pulse (Time-SLIP) with balanced steady-state
free precession (bSSFP) cine readout. CSF moved cephalic
(16.4 7.7 mm) during deep inhalation and caudal (11.6
3.0 mm) during deep exhalation in the prepontine
cisternal area. Small but rapid cephalic (3.0 0.4 mm)
and caudal (3.0 0.5 mm) movement was observed in the
same region during breath holding. Time-SLIP bSSFP cine
presents for non-invasive visualization of CSF movement
associated during deep expiration and expiration to a
degree not previously reported.
