Computerized Tomography (CT)
What is Computerized Tomography (CT or CAT Scan)?
A computed tomography (CT or CAT) scan allows doctors to see inside your body. It uses a combination of X-rays and a computer to create pictures of your organs, bones, and other tissues. It shows more detail than a regular X-ray.
You can get a CT scan on any part of your body. The procedure doesn’t take very long, and it’s painless.
What Is It Used For?
Doctors order CT scans for a long list of reasons:
- CT scans can detect bone and joint problems, like complex bone fractures and tumors.
- If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes.
- They show internal injuries and bleeding, such as those caused by a car accident.
- They can help locate a tumor, blood clot, excess fluid, or infection.
- Doctors use them to guide treatment plans and procedures, such as biopsies, surgeries, and radiation therapy.
- Doctors can compare CT scans to find out if certain treatments are working. For example, scans of a tumor over time can show whether it’s responding to chemotherapy or radiation.
