How A CT Scan Helps Diagnose Kidney Stones

A computed tomography (CT) scan is a diagnostic tool that uses X-rays and computers to create detailed cross-sectional images of your body. CT scans are often used to diagnose conditions such as kidney stones, tumors, and bone fractures. In this blog post, we’ll focus on how a CT scan can help diagnose kidney stones.

Kidney stones are hardened deposits of mineral and acid salts that form inside your kidneys. These small stones can cause big problems, including severe pain, inflammation, and blockages in your urinary tract. If you suspect you have kidney stones, your doctor may order ct scans for kidney stones to confirm the diagnosis.

How Does a CT Scan Work?

During a CT scan, you lie on a table while an X-ray technician circles around you, taking pictures from different angles. The images are then sent to a computer where they are assembled into 3D cross-sectional images of the inside of your body. The whole process takes about 30 minutes.

Your doctor will look at the images to see if there are any kidney stones present. If the stones are small, they may not be visible on the CT scan. In this case, your doctor may order an ultrasound or another imaging test to get a better look at your kidneys.

Are There Any Risks?

  • CT scans use X-rays, which carry a small risk of radiation exposure. This risk is highest for children and pregnant women because their bodies are still developing. However, the benefits of having a CT scan usually outweigh the risks for most people.
  • If you’re pregnant or think you might be pregnant, tell your doctor before having the CT scan. You may need to wait until after you give birth before having the scan.
  • People with kidney problems may also need to take special precautions before having a CT scan because contrast dye can further damage their kidneys.

The key to diagnosing kidney stones is getting an accurate image of your kidneys. A CT scan is a quick, painless, and noninvasive way to get that image. If you suspect kidney stones, discuss with your doctor whether a CT scan is appropriate for you.


CT scans are an important diagnostic tool for conditions like kidney stones, tumors, and bone fractures. If you suspect you have kidney stones, tell your doctor so they can order a CT scan. The scan itself is quick and easy, and it can give your doctor the information they need to make an accurate diagnosis and develop a treatment plan specifically for you.
