What is a LDCT (low-dose computed tomography)?

LDCT

LDCT takes many pictures of the inside of your body from

different angles using x-rays.

19

The amount of radiation used is much lower than standard doses

of a CT (computed tomography) scan.

19

First LDCT

If you are high risk for lung cancer you will have a LDCT test. Your

doctor will check for anything abnormal like a lung nodule.

23

Lung nodules

Screening with LDCT is used to find nodules in the lungs. Nodules

are small, round areas of abnormal tissue.

22

What happens after the first screening LDCT?

Follow-up or

yearly screening

LDCT

Your doctor will compare your second screening test to the

first screening test and decide when the next follow-up test will

happen.

26

Follow-up screening is done to check on your lungs at certain

time points like months or years.

26

How can I know for sure it’s lung cancer?

Biopsy or surgery

To test for cancer, tissue from the nodule must be removed from

your body. A biopsy removes a small samples of tissue. Surgery

removes the entire nodule for testing.

34

How do I decide between options?

Ask your doctors many questions. Also, you could get a second opinion, learn more about

screening tests, and compare the pros and cons.
