Low Dose CT Scan for Lung Cancer Screening

What Is a Low-Dose CT Scan for Lung Cancer?

Lung cancer is most treatable when it’s found early, before symptoms ever develop. A low-dose CT (LDCT) scan is a specialized imaging exam designed to detect small lung abnormalities that may not appear on a standard chest X-ray. Because the scan uses significantly less radiation than a traditional CT exam while still providing detailed images of the lungs, it has become the recommended screening method for people at higher risk of developing lung cancer.

The exam is fast, painless, and non-invasive. No needles, contrast dye, or medications are required. If any concerning findings are identified, you and your physician can discuss the appropriate next steps while treatment options are often at their greatest.

Why Choose Gateway Diagnostic Imaging for Your LDCT?

Choosing an outpatient imaging center can offer several benefits, including care close to home, a more relaxed environment, and the ability to return to your normal routine right after your exam. We work closely with referring physicians to ensure your results are interpreted promptly, allowing you and your healthcare provider to make informed decisions about your care.

Who is a Candidate for Lung Cancer CT Screening?

Low-dose CT lung cancer screening is recommended for adults who have an increased risk of developing lung cancer. Current screening guidelines generally recommend annual screening for individuals who:

  • Are between 50 and 77 years old, and
  • Currently smoke or quit smoking within the past 15 years, and
  • Have a smoking history of at least 20 pack-years, and
  • Do not currently have signs or symptoms of lung cancer

If you’re unsure whether you qualify, speak with your healthcare provider. They can help determine whether lung cancer screening is appropriate based on your personal health history.

What To Expect During Your Low Dose CT Lung Cancer Screening

The screening itself typically takes only a few minutes.

A technologist will position you comfortably on the CT scanning table. During the scan, the table will move slowly through the CT scanner while detailed images of your lungs are captured. You may be asked to hold your breath briefly to help produce the clearest possible images.

The exam is completely painless. There are no injections, no contrast dye, and no needles required. Most patients are in and out of the imaging suite quickly and can return to their normal activities immediately afterward.

What To Expect After Your Low Dose CT Lung Cancer Screening

Your images will be interpreted by a board-certified, subspecialized radiologist. Your results are sent promptly to both you and your referring physician so you can discuss any findings and determine whether any follow-up care is needed.

If no concerning findings are present, your physician may recommend returning for another annual screening if you continue to meet eligibility guidelines.
