Children who need a CT scan may need special
instructions for the test. If the child is too young to hold still or is
afraid, the doctor may give the child a medicine (sedative) to
help him or her relax.
If your child is scheduled for a CT scan,
talk with your child's doctor about the need for the scan and the risk of
radiation exposure to your child.
CT results are often compared to positron emission
tomography (PET) results to help find cancer. Some new scanners do both scans
at the same time.
CT scan of the spine is done with a
myelogram, it is called a CT myelogram. An MRI of the
spine is often done in place of a CT myelogram. To learn more, see the
