Low-dose CT Scans Detect Lung Cancer Earlier

Covenant Health offers low-dose CT scans as a diagnostic screening for lung cancer. Low-dose CT scans use lower amounts of radiation than standard chest CT imaging and creates detailed images of your chest and lungs to help detect cancer. We offer low-dose CT scans for lung cancer at the following hospitals:


Low-dose CT scans are recommended for individuals who: 

  • Are between the ages of 55-75 and have smoked one pack of cigarettes a day for 30 years;
  • Have past cancers of emphysema, pulmonary fibrosis, or a family history of lung cancer; and,
  • Have been exposed to substances such as asbestos, beryllium, chromium, diesel fumes,  nickel, silica, and arsenic.
  • Your physician must write an order for you to be screened.

What to Expect 

  • The screening is painless and takes about ten seconds.
  • This procedure is non-invasive and requires no medication.
  • You will lie still on a table as it passes through the center of the CT Scanner.
  • You may be asked to hold your breath one or more times during the scan.
  • You can eat and drink as normal before and after the exam.
