Children
Tips
• Children, who are more than 6 years old, should be
scanned with an adult protocol.
• The second recon job is defined with kernel H60s
and with an overlap for visualizing bone structures
with MPR.
• If the study is focused on bone structure only, the
mAs can be reduced to 20 for all age groups.
Contrast medium IV injection
Start delay exam dependent
Flow rate dependent upon needle size/Access site
Total amount 1 – 2 ml per kg of body weight
* The conversion factor for an 8-week-old,
and a scan range of 30 mm was used.
** The conversion factor for a 7-year-old, 100 mAs
and a scan range of 40 mm was used.

For the 2
nd
reconstruction the Autoload into the MPR
Range on the 3D Card is activated. The images will
be automatically loaded into 3D, MPR, and a coronal
MPRthick Range will pop up. Please notice, if you are
not satisfied with the Range preset adapt the para-
meters to your needs and link them to the series.
