The permeability
analysis was performed using the IntelliSpace portal, manufactured by PHILIPS
with the Permeability package. The variables changed during processing were the
AIF, temporal and spatial smoothing filters.
For
each equipment field strength a processing protocol was created informing
the injection time, the relaxativity and the concentration of the contrast
agent.
There is a
significant difference in the values of permeability between the Manual and
Automatic AIF processing. Temporal smoothing filters showed greater variation
when using the medium setting.
