CT SCANS (Computed Tomography)
What
is CT (or CAT scan)?
A CT (also known as CAT scan or Computed Axial Tomography) is a
special X-ray which shows your doctor detailed cross-sectional anatomy
including major organs, soft tissue and bone.
Why
is a CT necessary?
CT provides many benefits and is effective in the clinical evaluation
of organs, soft tissues and bones in order to detect specific infections,
cancers, embolism, aneurysms, blockages, abnormal growths, tumors,
enlargements, injuries or deformities.
What
should I wear?
Wear clothing that is comfortable without metal buttons or zippers
if possible (i.e., sweat pants, t-shirt, shorts, etc). It may be
necessary for you to change into a patient gown depending on the
area to be scanned.
Are
there any special preparations or restrictions for my CT exam?
In many cases there is some preparation. Some procedures require
you to not eat or drink prior to the exam, and abdominal studies
require patients to drink an oral contrast material. If your exam
requires an intravenous contrast, please do not eat anything for
3-4 hours prior to the exam. Exams requiring contrast material include
scans of the head, soft tissue neck, chest, abdomen, and pelvis.
Your doctor’s office will inform you if any special preparation
is required prior to your exam. If you have further questions, please
call 706-278-XRAY(9729).
Can
I have a CT scan during pregnancy?
No. Radiation can be very harmful to an unborn fetus. You should
not have any type of X-rays during pregnancy. If there is any possibility
that you may be pregnant, please inform your technologist.
May I have a CT scan when I am breastfeeding?
If you have contrast as part of your exam, please suspend nursing
for 24 hours after the scan.
What
should I expect during my exam?
CT is a painless procedure, although some exams do require an intravenous
contrast injection. You will lie on a table that moves through the
scanner, which is an open “donut” shaped machine. For
some procedures you may be asked to hold your breath for short intervals.
Procedures take from 10-30 minutes to complete.
When
can I receive my results?
Your results will be faxed to your doctor’s office the same
day as your exam. A radiologist is available to tailor the exam
and discuss any concerns you may have. Dalton Imaging Center will
also provide the films to your doctor’s office upon request.
Because Dalton Imaging Center recognizes that tests and other medical
procedures can be unsettling at times, we make every effort to completely
answer any questions related to testing procedures.

with a contrast material, you will receive an injection about half
way through the exam; please do not eat for three hours prior to
your exam. This exam will take approximately 20 minutes.

Abdomen and Pelvis
For a CT scan of your abdomen and pelvis, it will be necessary to
drink an oral contrast agent 1 hour prior to the exam in order to
better image the gastrointestinal system. For this procedure, patients

table and hold your breath for short intervals. If your doctor has

an injection about half way through the exam. Do not eat or drink
