| What
about some of the words you will hear about
the CT?
Intravenous injection
(IV):
A small needle placed in the hand, arm or foot
used to inject contrast material or sedation.
Contrast material:
A liquid that helps produce a better picture
during the exam and is given in an IV
The patient may need IV contrast - a liquid
which helps produce a better picture when put
into the body through the veins - for the exam.
In that case, the patient should eat or drink
for 1-2 hours before the appointment.
Sedation may be needed. A child or adult who
needs sedation cannot have solid foods, formula
or milk for six hours before the scan. |
How
is a CT scan picture made?
The CT technologist or radiology nurse will
bring you into the CT room. At this time, if
IV contrast is needed, an IV will be started.
The radiologist, a doctor who is specially trained
to look at X-rays nurse or technologist will
help you lie down on the scan table. A safety
belt can be inserted around the chest and arms,
and a small strap will go across the forehead.
If your child cannot hold
still, sedation will be given at this time.
Contrast may also be given at this time, if
needed. The pictures will take few minutes.
During the scan, the table will move slowly
into a large ring-shaped machine.
|
| Who
performs the exam?
The CT technician, the radiology nurse and the
radiologist perform the exam.
|
| Who
looks at the results?
The radiologist (usually a Professor) will view
all the pictures and then write a complete report. |
| Is
there any risk from the radiation?
As with any X-ray, radiation is a risk. However,
CT scans helps collecting a maximum of information
with the smallest amount of radiation.
|
| What
happens after the CTscan?
The technician or nurse will provide you with
any special instructions you need and tell you
when you may leave.
