How to do it
Scan protocols
There are two Scan protocols available:
BrainPerfCT, a non contrast study and a Dynamic
Serio with 12 mm collimation and 2 times a 12 mm
slice thickness.
BrainPerfSingle, a non contrast study and a Dynamic
Serio with 5.0 mm collimation and one 10 mm slice
thickness.

Such a standard protocol may be slightly modified for
specific reasons; e. g. the start delay can be increased
by a few seconds for patients with very low cardiac
output.
