General Time

Most CT scans take about 15 to 30 minutes. This includes getting ready, doing the scan, and finishing up. The part where the machine takes pictures only takes a few minutes. The rest of the time is spent setting up and making sure everything is perfect for clear pictures.

CT Scans with Contrast

Sometimes, doctors use a special dye called contrast. This dye makes the pictures even clearer by highlighting certain areas inside your body. If you need contrast, the scan might take 10 to 20 minutes longer. This is because you might need to drink the dye or have it given through an IV.

Different Types of Scans

  • Tummy Scans: About 20 to 30 minutes, depending on whether contrast is used.
  • Lung Scans: Less than 20 minutes for a detailed view of your chest.
  • Brain Scans: Around 10 to 20 minutes, perfect for checking for injuries or issues.

When Will You Get the Results?

After the scan, a special doctor called a radiologist looks at the pictures. They tell your regular doctor what they see. Usually, you’ll get the results in a day. If it’s really important, you might hear back in a few hours. The radiologist’s report helps your doctor decide what happens next.

Your doctor will explain what the pictures show and let you know if you need more tests or treatments. They’ll guide you through the next steps, whether it’s medicine, therapy, or another scan.

Why Do CT Scans Take Longer Sometimes?

Getting Ready

Before the scan, you might need to change into special clothes, take off jewelry, or fill out a form. If you need to drink the contrast dye, that can take extra time. Preparing the equipment and making you comfortable is important for accurate results.

Some scans are more detailed than others. If the machine has to take lots of pictures, it might take a little longer. For example, a full-body scan will take more time than a scan of just your brain or chest.
