Hints in General
1.Topograms: 256 mm lateral topograms are defined
for the head modes, and 512 mm TOP topograms
are defined for the body modes. Please keep in mind
that the children’s size can be dramatically different.
You should press the “Hold Measurement“ button
whenever the range shown on the real-time grow-
ing topogram is long enough, in order to avoid
unnecessary radiation.
2. Gantry tilt is available for both, sequence and spiral
scanning. However, image artifacts may occur if spi-
rals are acquired with a tilt angle greater than 8°.
3.For all head studies, it is very important for image
quality purposes to position the patient in the center
of the scan field. Use the lateral laser beam to make
sure that the patient is positioned in the center.
4.Warm surroundings and dimmed lighting are helpful
to make children more cooperative.
5.Sedation: Although the advent of the Multislice CT
scanner has enabled the user to scan through an
area of interest much faster than ever, sometimes,
patient motion can still lead to severe motion arti-
facts seen on the resultant images. This becomes a
factor especially with infants and younger children
who are unable to hold still for the exam. Sedating
this population may be a viable option for your insti-
tution. Of course, appropriate protocols need to be
established at your specific institution. For instance,
the drug of choice for specific ages/weights of these
patients (taking into consideration the total time of
the exam), the form of administration, patient
preps, adequate monitoring of the patient (pre-scan,
during the exam and post-scan) etc. should all be
taken into consideration.
