CT scans offer your gastroenterologist a unique glimpse into your body’s digestive function, helping to diagnose a range of GI issues. By creating a detailed cross-sectional image of the abdomen, a CT scan can be used to detect tumors, blockages, infections, bleeding, and more. Imaging can also be used to monitor treatment progress and catch complications early.
Here at Charleston GI, our experienced physicians are equipped to treat a wide variety of GI conditions. Effective treatment starts with a thorough examination – and CT scans play a major role in providing accurate diagnoses.

WHAT TO EXPECT BEFORE THE CT SCAN
Preparation Steps
Your GI physician may recommend the following:
Remove clothing and put on a hospital gown.
Take off anything metal, like belts, jewelry, glasses, dentures, etc.
Avoid eating or drinking for a few hours before the CT scan.
Child Preparation Steps
If your infant or toddler needs a CT scan, a sedative may be prescribed.
Ask your doctor ahead of time about how best to keep your child still during the procedure.
WHAT TO EXPECT DURING THE CT SCAN
Our Process
You will lie on a narrow table that moves slowly through the scanner, which looks similar to a large doughnut. Straps and pillows may be used to help you remain in the proper position. For head CT scans, a special cradle may be utilized.
Your Experience
As the X-ray tube rotates around, you will likely notice whirring or buzzing sounds. Multiple images of thin slices of the body will be taken as your CT tech instructs you from another room. Instructions may include holding your breath to prevent blurry imaging.
WHAT TO EXPECT AFTER THE CT SCAN
Returning to Normal Activities
Most patients resume their regular activities right away. If contrast dye was used, you may need to wait briefly before leaving, and drink plenty of fluids the remainder of the day.
Getting Your Results
CT images are stored electronically and analyzed by a radiologist. Your gastroenterologist will then discuss your results, as well as your treatment options moving forward.
RISK FACTORS
Because CT scans expose you to a small dose of radiation, they very slightly increase your risk of developing cancer. Keep in mind that the FDA estimates that the risk of cancer from a CT scan is much lower than the risk of getting cancer naturally.
It depends on whether or not contrast dye is needed. If dye will be used, patients are typically asked to fast for about three or four hours before. If not, patients can eat and drink normally prior to a CT scan.
What happens if I eat before a CT scan?
For CT scans not requiring contrast dye, you are free to eat and drink as usual. But if contrast dye will be used, your GI doctor will recommend not eating solid foods three hours prior to the test to avoid nausea and vomiting. Failing to comply may result in a rescheduled visit.
Why would a doctor recommend a CT scan?
A CT scan helps doctors accurately diagnose a variety of GI issues, providing a detailed look at the body’s bones, organs, and tissues.
What conditions can a CT scan detect?
A CT scan may be used to help diagnose the following:
Bone and muscle issues: Detect fractures and bone tumors
Infections and tumors: Pinpoint tumors, infections, or blood clots
Internal injuries: Locate internal bleeding or injuries caused by trauma
How is a CT scan used in medical procedures?
GI doctors use CT scans in the diagnosis and treatment of digestive conditions. They are used during surgeries and biopsies, as well as radiation therapy.
Can a CT scan track disease progression?
Yes. In fact, a CT scan helps monitor diseases like these:
Cancer: Checks if tumors are growing or shrinking
Heart disease: Detects blockages or blood vessel damage
Lung nodules and liver masses: Tracks any changes over time
Can a CT scan show if a treatment is working?
Absolutely. CT scans are a great way to determine if a treatment is on track.
What is a CT scan?
A CT (computerized tomography) scan is a type of imaging that uses X-rays and a computer to create cross-sectional images of the body. These images, also called slices, show the bones, blood vessels, and soft tissues in greater detail than x-rays.
