A Step-by-Step Guide to CT Scan Preparation
A Computed Tomography (CT) scan is a powerful diagnostic tool that combines X-rays and computer technology to create detailed images of the inside of your body. These images help doctors diagnose diseases, plan treatments, and monitor conditions. Preparing correctly is essential for a smooth and effective scan. Pittsburgh Imaging & Wellness created this guide to help you understand the process and feel confident on the day of your appointment.
Talk to Your Doctor
Communication is the first and most important step. Before your scan, have a detailed discussion with your doctor about your health.
You should inform them about:
- Allergies: Be sure to mention any known allergies, especially to iodine or contrast materials used in previous imaging tests.
- Medications: Provide a complete list of all medications you are taking, including prescriptions, over-the-counter drugs, and supplements.
- Medical History: Discuss any pre-existing conditions, particularly kidney problems, diabetes, or thyroid issues. This information helps the medical team ensure the procedure is safe for you.
- Pregnancy: If you are pregnant or think you might be, it is crucial to tell your doctor. While the radiation dose from a CT scan is low, your doctor may suggest an alternative imaging test, like an MRI or ultrasound, to avoid any risk to the fetus.
Follow Diet and Fluid Instructions
Depending on the type of CT scan you're having, you may receive specific instructions about eating and drinking.
- CT Scan without Contrast: If your scan does not involve a contrast dye, you can usually eat, drink, and take your medications as normal.
- CT Scan with Contrast: If your scan requires a contrast dye, you will likely need to fast for a few hours beforehand. This usually means no solid foods for about 4 to 6 hours before the appointment. You may be allowed to drink clear liquids, but it's best to confirm this with your provider. Fasting helps prevent nausea, a possible side effect of the contrast material.
| Scan Type | Fasting Required? | Why? |
|---|---|---|
| CT without contrast | No | No contrast dye is used, so there is no risk of nausea. |
| CT with contrast | Yes (usually 4-6 hours) | Reduces the risk of nausea or an upset stomach from the contrast dye. |
Understand Contrast Material
Contrast materials, often iodine-based, are special dyes used to improve the clarity of the images. They can be administered in a few ways:
- Orally: You might be asked to drink the contrast solution.
- By Injection: The dye is injected into a vein, usually in your arm. This can create a warm, flushed sensation.
- By Enema: The contrast is given rectally for scans of the lower digestive tract.
If your scan requires contrast, Pittsburgh Imaging & Wellness may order blood work ahead of time to check your kidney function, as the kidneys help filter the dye out of your body.
What to Wear on the Day of Your Scan
Choosing the right attire can make your experience much more comfortable.
- Clothing: Wear loose, comfortable clothes without any metal zippers, snaps, or buttons. Athletic wear or sweats are often a good choice.
- Metal Objects: You will need to remove all metal from your body, as it can interfere with the CT images. This includes jewelry, eyeglasses, dentures, and hairpins. It’s easiest to leave these items at home.
- Medical Devices: Inform the technologist about any medical devices you have, such as a pacemaker or insulin pump.

Frequently Asked Questions

How long does a CT scan take?
The scan itself is usually very quick, often lasting less than a minute. The entire appointment, including preparation and check-in, typically takes between 30 and 60 minutes.
Can I drive myself home after a CT scan?
Yes, in most cases, you can drive yourself home after a CT scan. The procedure does not typically involve sedation. If you received a contrast dye, you will be encouraged to drink plenty of fluids to help flush it from your system.
What happens if you eat before a CT scan with contrast?
Eating before a CT scan with contrast can increase the risk of nausea and vomiting. If you accidentally eat, your appointment may need to be rescheduled to ensure your safety and the quality of the scan.
Is a CT scan painful?
