Before getting an CT scan, here are some key things patients should know:
​
1. Purpose of the CT Scan
-
A CT scan uses X-rays and computer processing to create detailed images of the body.
-
It’s used to diagnose or monitor conditions such as injuries, infections, tumors, or internal bleeding.
2. Radiation Exposure
-
CT scans involve low doses of radiation. While generally safe, repeated exposure should be minimized. Let your doctor know if you’ve had many scans or are concerned about radiation.
-
Inform your doctor if you are pregnant or suspect you might be, as radiation may pose risks to the fetus.
3. Preparation
-
Eating and Drinking: You may be asked to avoid eating or drinking for a few hours before the scan, especially if contrast dye is used.
-
Clothing: Wear comfortable, loose clothing without metal components, or you may be asked to wear a hospital gown.
-
Metal Objects: Remove jewelry, glasses, dentures, or any metal objects that could interfere with imaging.
4. Contrast Dye
-
Some scans require a contrast dye to enhance image clarity. This may be given orally, through an IV, or as an enema.
-
Inform your doctor of any allergies, particularly to iodine or shellfish, as these could indicate a risk of an allergic reaction to the contrast dye.
-
Side effects of the dye are rare but may include a warm sensation, metallic taste, or mild nausea.
5. Health Conditions
-
Inform your doctor if you have kidney problems, diabetes, or take medications like metformin, as these may affect your ability to process contrast dye.
6. Procedure Expectations
-
The scan is painless and usually takes 10-30 minutes.
-
You’ll need to lie still on a table that moves through a large, donut-shaped machine.
-
The machine makes whirring noises, but you’ll typically be able to communicate with the technician through an intercom.
7. After the Scan
-
Most people can resume normal activities immediately.
-
If contrast dye was used, drink plenty of fluids to help flush it from your body.
8. Discuss Concerns with Your Doctor
-
If you feel claustrophobic or anxious, ask about sedation options.
-
Share any specific concerns or questions with your healthcare provider before the procedure.
Proper preparation ensures a smoother process and more accurate results!
