How does a CT chest scan work?

A CT chest scan (also called a chest CT or thoracic CT) uses advanced X-ray technology to take detailed cross-sectional images of the structures inside your chest — including your lungs, heart, airways, and blood vessels.

Note: The Everlab Protocol uses a Non-Contrast CT Chest, meaning no dye or contrast agent is injected during the scan. This makes the procedure quicker and more comfortable, while still providing high-resolution imaging of your chest.

1. You'll lie on a motorised table
   The table will slowly move you through a large, doughnut-shaped scanner. This machine is open at both ends and does not enclose your entire body, making it suitable even for those who are mildly claustrophobic.

2. The scanner captures detailed images
   As you pass through the scanner, it uses low-dose radiation to take a series of images from various angles. A computer then compiles these into 3D views, giving your Everlab doctor a comprehensive look at your chest.

3. You may be asked to hold your breath
   Holding your breath for a few seconds during the scan helps reduce motion and ensures clearer images.

4. Quick and painless
   The entire procedure usually takes about 10 to 15 minutes, though the scanning itself often lasts just a few minutes.

CT chest scans are used to assess:

• Lung health (e.g. infections, nodules, or other abnormalities)

• Cardiovascular structures such as the aorta or pulmonary arteries

• Early signs of conditions like emphysema or lung cancer (in high-risk patients)

After your scan, a radiologist and your Everlab doctor will review the images and explain the results during your follow-up.
