MR vascular images are obtained after the acquisition of
several cardiac cycles followed by an average of these
measures. In this case, we do not have the true cardiac
information and respiratory influence is lost. The aim
of the present study was to apply a near real time
imaging to follow physiological changes in CSF, arterial
and venous flows. Moreover, we expose the principle of
an automatic Fourier-based method to extract respiratory
and cardiac frequencies in fast MR images and to assess
the contribution of the two physiological phenomena to
the signal obtained during MR acquisitions in various
fluids.
