This is a medical imaging method that generates a 3-dimensional image of the
inside of an object from a large series of 2-dimensional X-ray images.
Doctors often choose CT scans to diagnose cancer, particular cancer in the lungs, liver or pancreas. The scans allow the doctor to locate and measure the cancer very precisely. Medical professionals also use these scans to study the chest, abdomen and pelvis for other non-cancerous conditions and injuries. Spinal problems and injuries to the skeleton that do not show up well on x-ray are shown on CT scans. Because CT scans can show blood vessels in great detail, doctors use them to detect and diagnose types of vascular disease.

DOES CT-SCAN HURT?
CT imaging itself is painless. The patient is required to remain motionless during the examination (which is difficult for some people), but the actual scan causes no bodily sensation.
HOW LONG DOES THE EXAM TAKE?
The exam usually takes from 10 minutes to 30 minutes. This allows for
preparation as well as time for the computer to generate the image. Actual
exposure time is minimal. Time may vary significantly depending on the
nature of the study and other factors.
HOW WILL I LEARN ABOUT THE RESULTS?
The radiologist, a physician specialist, will study the results of your
exam and discuss them with your doctor, who will then consult you.
ARE THERE ANY CONDITIONS I NEED TO MAKE KNOWN?
It is important to notify the person performing the test of any illness, allergy, or previous drug reaction.
In general, no special preparation is required for a CT scan.
Comfortable, loose clothing should be worn, although in some cases a
patient will be asked to change into a hospital gown for the examination. It
is also important to remove any metal prior to the exam: jewelry, dentures,
eyeglasses, belt buckles, and metal zippers and buttons can interfere with
A patient may be asked to limit eating and drinking to clear liquids,
such as water, black coffee and tea, and broth for several hours prior to
the appointment for a CT scan. This request will be dependent upon the
facility and the type of examination.
For many CT examinations, a contrast agent (a liquid that enhances
imaging of certain organs or blood vessels) will be administered. Depending
on the type of examination, the contrast may be given orally, intravenously,
or as an enema. If certain types of contrast will be used during an
examination, the patient may be required to fast for several hours or use an
enema to cleanse the colon prior to his/her appointment.
