Tips
• Children with a body weight of more than 54 kg
should be examined with an adult protocol.
• If you want to acquire the patient at full inspiration
or full expiration, you should practice the breathing
with the patient a few times before beginning the
scan, so that reproducibility may be improved.
* The mAs should be adjusted to the body weight
of the child.
* The conversion factor for an 8-week-old,
and a scan range of 150 mm was used.
