How Long Does a CT Scan Take? What to Expect

If your doctor has ordered a CT scan, one of your first questions might be: “How long does a CT scan take?” The good news is that most CT scans are quick, non-invasive, and typically completed in less than 30 minutes from start to finish.

But there’s more to the story than just the scan itself. From the moment you walk in the door to when you leave, several steps go into making your visit safe, accurate, and comfortable. At Craft Body Scan, we believe in transparency—so you know exactly what to expect at every stage of your visit.

This article walks you through the full CT scan experience: how long it takes, how to prepare, and how we prioritize patient care every step of the way.

Overview of a CT Scan Procedure

A CT scan, or computed tomography scan, is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce cross-sectional images of the body. These detailed images allow medical professionals to examine internal organs, bones, blood vessels, and tissues with exceptional clarity.

Here’s what happens during a typical CT scan visit:

• Check-in and paperwork
• Pre-scan preparation (including contrast dye if required)
• The actual scan
• Post-scan guidance and results timeline

While the scan itself often takes only a few minutes, the total time you spend at the imaging center depends on what type of scan you need, whether contrast is used, and your medical history.

Typical Duration of a CT Scan

So how long does a CT scan take, really?

Here’s a breakdown of time based on the part of the body being scanned:

• Head or Brain CT: 10–15 minutes
• Chest CT: 15–20 minutes
• Abdominal or Pelvic CT: 20–30 minutes
• Full-Body CT: 30–45 minutes
• With Contrast Dye: Add 10–15 minutes for preparation and reaction monitoring

In most cases, the actual scan portion lasts just a few minutes—often less than five. The rest of the appointment time includes pre-scan instructions, potential contrast dye administration, and post-scan wrap-up.

At Craft Body Scan, our workflow is streamlined so that even more complex scans rarely take longer than 30–45 minutes in total.

What to Expect During the Scan

If you’ve never had a CT scan before, the idea of getting one might sound intimidating. But rest assured, the process is simple and painless. Here’s what you can expect when you arrive for your scan:

1. Arrival and Check-In: You’ll check in at the front desk and complete any necessary paperwork. Our staff will verify your insurance, health history, and any prior imaging records.
2. Preparation: Depending on your scan, you may be asked to change into a gown and remove any metal objects like jewelry or belts. If your scan requires contrast dye, it may be given orally or through an IV.
3. Scan Positioning: You’ll lie on a padded, motorized table that moves into a large, circular scanner. Our technician will make sure you’re positioned comfortably.
4. The Scan: As the machine rotates around you, it captures hundreds of images. You’ll hear soft whirring or clicking sounds, but you won’t feel anything. You’ll be asked to lie still and may occasionally be instructed to hold your breath for a few seconds.
5. Post-Scan: After the scan, if contrast dye was used, you may be asked to wait briefly for monitoring. Otherwise, you can typically get dressed and go about your day.

FAQs About CT Scans and Timing

1. Can I eat or drink before my CT scan?
It depends. Some scans (especially with contrast) require you to fast for a few hours. You’ll receive specific instructions when you schedule your appointment.

2. Does a CT scan hurt?
No. The procedure is completely painless. If contrast dye is used, you may feel a warm sensation, but it’s brief and normal.

3. How long will I be at the imaging center?
Most appointments at Craft Body Scan take 30 to 45 minutes in total, even for more advanced scans.

4. When will I get my results?
Scan results are usually available within 24–48 hours and are sent directly to your healthcare provider. We can also assist with review and next steps if needed.

5. Do I need someone to come with me?
Not necessarily. Unless sedation is used (which is rare), you can drive yourself home and resume normal activities after the scan.

CT Scans With and Without Contrast: What’s the Difference?

One factor that affects how long your CT scan appointment takes is whether it involves contrast dye. This material enhances the visibility of certain tissues and blood vessels, making it easier for radiologists to detect abnormalities.

Here’s how it changes the process:

• With Contrast: Extra time is needed for dye administration and post-scan observation (usually adds 10–15 minutes).
• Without Contrast: The process is faster, and you’ll be in and out more quickly.

Not every CT scan requires contrast, and the decision is based on what your doctor needs to evaluate.

When Is the Best Time to Get a CT Scan?

There’s no universal answer, but timing can be critical for certain conditions. CT scans are especially helpful for:

• Sudden or unexplained pain
• Suspected internal injuries
• Monitoring known medical issues
• Cancer screenings or follow-ups
• Preventive health assessments

If you’re getting a scan for screening purposes, early morning appointments often allow for same-day results and quicker access to follow-up care.
