Scan
How Does It Work ?
What Is Computed Tomography Scan (CT Scan)?
Computed tomography (CT) combines the use of X-rays with the
latest computer technology to create cross-sectional images
of your body. Because some of these slices are as thin as
0.5 mm, our 16-slice CT system offers more detail than traditional
X-ray. As a result, CT is an ideal way to accurately view
the size, shape and position of structures such as the lungs,
liver, kidneys and other internal organs.
How do I prepare for this exam?
You may need to make changes in your diet to prepare for your
scan. You also may need to drink Contrast (a special "dye"
that enhances the image) the night before. Follow prep instructions
carefully. Your scan may need to be rescheduled if you do
not.
Let the technologist know:
For your safety, let the technologist know about any of the
following:
-Allergies
-Kidney problems
-Diabetes medication you take
-If you are pregnant or think you may be
-If you ate or drank before the test
During your exam:
You may be asked to wear a hospital gown. You also may be
given a contrast through an intravenous (IV) line or by injection.
The contrast may make you feel warm or give you a strange
taste in your mouth. This will pass quickly. You will lie
on a platform that slides into a doughnut-shaped hole. The
technologist will ask you to hold your breath for a few seconds
during your scan. You may have to wait briefly to make sure
the images are of good quality.
For your comfort:
- Relax and remain as still as you can
-Know that a CT scan is painless
-You may find that focusing on what the technologist says
will speed up the process.
How long will this exam take?
Each exam varies in length of time depending on many different
factors. The average time for a CT Scan is approximately 30
to 60 minutes. Feel free to ask the technologist before beginning
the exam any questions you may have about the exam or amount
of time needed to complete the exam.
