When you’re facing a medical emergency, time is critical, and waiting for imaging shouldn’t slow you down. That’s why Altus Emergency Center offers on-site imaging with CT scan capabilities, providing fast, accurate results without the delays of off-site referrals. Most CT scans take just 10 to 30 minutes, including prep and positioning, with the scan itself lasting only a few minutes. Our goal is to make the process quick, efficient, and stress-free, so you can get the answers you need and the care you deserve, right away.
What Is a CT Scan?
A CT (Computed Tomography) scan is a non-invasive imaging test that uses X-rays and computer processing to create detailed pictures of your internal organs, bones, blood vessels, and soft tissues. It helps doctors diagnose:
- Head injuries or strokes
- Abdominal or chest pain
- Infections or internal bleeding
- Bone fractures
- Tumors or abnormal growths
Because CT scans are so precise, they’re often used in emergency care settings where fast, accurate diagnosis is essential.
What Factors Affect How Long a CT Scan Takes?
Several things influence the total time it takes:
1. Type of Scan
A basic head or chest scan is often faster than a full abdominal or spinal scan. Full-body scans take longer due to the area being covered. More complex scans may also require additional image slices and angles. Scans targeting internal organs may take more time for positioning and calibration.
2. Use of Contrast Dye
Some scans require a contrast dye, taken orally or via IV, to highlight specific organs or blood vessels. If contrast is used, expect a short wait for the dye to circulate. You may also need a brief monitoring period to ensure there’s no allergic reaction. The type of contrast (oral or IV) and the area being scanned will determine how long you wait.
3. Movement and Retakes
If you move during the scan or need to repeat an image, this can extend the time slightly. Staying still during the scan helps avoid delays. Even minor movements can blur results, making retakes necessary. Technicians will guide your breathing and positioning to help reduce errors.
How Long Is the Actual Scan?
Once you’re positioned and ready, the scanning itself usually takes less than 5 minutes. However, plan for about 10 to 30 minutes total, including prep and follow-up. At Altus ER, our on-site radiology techs work hand-in-hand with our emergency doctors to review and explain results promptly, so your care plan can start right away.
What to Expect During Your CT Scan
Here’s what you can expect during the procedure:
- Preparation and Positioning
You’ll lie down on a flat table, usually on your back. Depending on the area being examined, you may be asked to lie on your side or stomach. A technologist will ensure you’re correctly positioned and comfortable before beginning. - Movement into the Scanner
The table will slowly slide into the circular opening of the CT machine. It’s important to stay still to ensure the images come out clear and accurate. - Breath-Holding Instructions
You might be asked to hold your breath for a few seconds, usually under 20 seconds, to reduce movement and improve scan quality. - Image Capturing Process
The scanner rotates around your body to capture cross-sectional images. The machine is relatively quiet, and the process is usually quick and painless. - After the Scan
Once the imaging is done, the table moves out of the scanner. Most scans take just a few minutes, and you can usually resume normal activities right away. - Guidance by a Certified Technologist
A trained CT technologist will be with you throughout the process. They’ll guide you, explain instructions, and monitor everything from a nearby control room.
When Should You Get a CT Scan?
Your doctor or ER physician may recommend a CT scan if you’re experiencing:
- Sudden headaches or dizziness
- Chest or abdominal pain
- Difficulty breathing
- Loss of consciousness
- Injury after an accident
- Symptoms of stroke or internal bleeding
If you’re unsure whether you need a scan, it’s always better to seek medical attention, especially when symptoms are severe or sudden.
Are There Any Risks or Side Effects of a CT Scan?
CT scans are widely considered safe and effective for both adults and children. However, it’s natural to have questions about possible risks. Here’s what you should know:
- Minimal Radiation Exposure
CT scans use a small amount of ionizing radiation, similar to X-rays. The levels are low and carefully controlled by medical professionals to ensure your safety. - Safe for Children and Adults
Healthcare providers take extra precautions when performing scans on children, using the lowest possible radiation dose while still producing clear images. - No Direct Side Effects from the Scan Itself
The scan itself is painless and typically doesn’t cause any side effects. You can resume normal activities immediately after the procedure. - Possible Reaction to Contrast Material
If contrast dye is used to enhance the images, a few people may experience mild side effects such as:
- Nausea or vomiting
- Headache
- Dizziness
- Nausea or vomiting
