Why Would Someone Need a CT Scan?

If your doctor has ordered a CT Scan, you may be wondering why. A CT Scan is one of the most common imaging tests in medicine, and doctors rely on it for many different reasons, from checking an injury after a fall to finding the cause of unexplained pain.

At Crown Imaging, a family-owned imaging center serving Dallas since 2002, we perform CT Scans for patients referred by doctors across the area. Here’s a look at the most common reasons doctors order a CT Scan and what you can expect during your exam.

What Is a CT Scan?

A CT Scan, short for computed tomography, uses X-rays and computer processing to create detailed cross-sectional images of the inside of your body. Think of it like looking at a loaf of bread one slice at a time. Each “slice” gives your doctor a clear view of bones, organs, blood vessels, and soft tissues that a standard X-ray can’t show in as much detail.

Because CT provides fast cross-sectional imaging, it’s often the go-to test when doctors need clear answers quickly.

Common Reasons Doctors Order a CT Scan

1. Injuries and Accidents

After a car accident, a bad fall, or a sports injury, a CT Scan can help doctors check for broken bones, internal bleeding, and damage to organs. Because the scan is so fast, it’s often one of the first tests used when someone has been seriously hurt.

2. Unexplained Pain or Symptoms

When you have symptoms without a clear cause, a CT Scan can help your doctor narrow down what’s going on. For example, it’s often used to look for the source of severe abdominal pain, which can point to problems such as appendicitis or kidney stones.

3. Head and Brain Concerns

Doctors may order a CT Scan of the head after a head injury or when someone has symptoms like a sudden, severe headache. It can help show bleeding, swelling, or signs of a stroke, especially when quick answers matter.

4. Lung and Chest Problems

A CT Scan of the chest can show more detail than a chest X-ray. Doctors use it to look for infections like pneumonia, lung nodules, and other conditions affecting the lungs and chest.

5. Bone and Joint Issues

CT is excellent at showing bone detail. It can help doctors evaluate complex fractures, spine problems, and joint conditions, and it’s sometimes used when an X-ray doesn’t give the full picture. Curious how the two compare? Read our guide on CT Scan vs. X-Ray and when doctors choose each test.

6. Blood Vessel Concerns

With the help of contrast material, a CT Scan can give doctors a clear view of blood vessels. This can help them look for blockages, aneurysms, and other vascular issues.

7. Cancer Care

CT Scans play an important role in cancer care. Doctors use them to find tumors, see how large they are and whether they have spread, and track how they respond to treatment over time.

8. Planning and Guiding Procedures

Surgeons often use CT images to plan operations. In some cases, CT is also used to help guide a needle to the right spot during a biopsy.

Why Choose a CT Scan Over Other Imaging Tests?

Every imaging test has its strengths, and your doctor chooses the one that best fits your situation. CT is often chosen because it’s fast, shows bone and soft tissue together, and works well when quick results are needed. MRI, on the other hand, is often preferred for detailed views of soft tissues like ligaments and the brain. To learn more, see our article on MRI vs. CT Scan and which one you need.

If you’re not sure why your doctor ordered a CT Scan, ask them. They can explain what they’re looking for and why they chose this test.

What to Expect During Your CT Scan

Before Your Scan

Preparation depends on the type of CT Scan you’re having. Some exams need little or no preparation, while others may ask you to avoid food or drinks for a period of time. Our article on whether you can eat or drink before a CT Scan explains why instructions vary. Always follow the specific instructions you receive for your exam.

Wear comfortable clothing without metal zippers or buttons, and be ready to remove jewelry or other metal items. Let our team know if you are or might be pregnant.

During Your Scan

You’ll lie on a padded table that slowly moves through the opening of a ring-shaped scanner. The scanner rotates around you to capture images from different angles. You’ll need to stay still, and you may be asked to hold your breath for a few seconds at a time. Your technologist will guide you through each step and can talk with you throughout the exam.

After Your Scan

Most patients can return to their normal activities right away unless their doctor says otherwise. A radiologist reviews your images and sends a report to your doctor, who will go over the results with you.
