What are CT scans used for?

ANSWER

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.
