Abstract
Two-dimensional cine phase-contrast
MRI has been demonstrated effective in the
evaluation of the cerebrospinal fluid (CSF)
hydrodynamics in different intracranial
pathological conditions. In the aqueduct of
Sylvius from which the CSF velocity-to-time
curve was calculated and calibrated, we
noticed that the existence of a notch
waveform which is different in normal
pressure hydrocephalus patients (NPH),
normal healthy subjects, and communicating
hydrocephalus (CH) patients. According to
the flow patterns, we scaled into 0, 1 and 2
score for non-existing, mild, and significant
presence, respectively, of the notch
waveform. The purpose of this project is to
correlate the hydrodynamic parameters
derived from the CSF flow pattern in a
cardiac cycle with the presence of notch, and
further to discuss the possibility to
investigate the transmission of pressure wave.
Through an understanding of the relationship,
an analysis of the notch waveform in CSF hydrodynamics may have potential in
estimating intracranial pressure.
