Tips
• Children, who are more than 6 years old, should
be scanned with an adult protocol as the skull by this
time is fully grown.
• The UHR mode requires a 250 mm scan FOV. It is
mandatory to position the patient in the center of
the scan FOV.
• When soft tissue is of interest, use kernel U30 for
image reconstruction.
