Low-Dose CT Lung Cancer Screening

Low-Dose Computed Tomography (CT) Screening for people at high risk for lung cancer.

Lung Cancer CT ScanLung cancer remains the most common cause of cancer death in the United States and Canada. The publication of the National Lung Screening Trial (NLST) has established the ability of low-dose computed tomography (LDCT) scans to decrease lung-specific mortality by 20% in a screened high-risk population. Early detection is a proven, successful strategy.

About Low-Dose CT Lung Cancer Screening

What is Low-Dose CT Lung Cancer Screening?

The exam for CT lung cancer screening is a low-dose CT exam, with a radiation dose of approximately 1.5 mSv (millisieverts), equivalent to approximately half of the naturally occurring background radiation that a person receives for one year at sea level.

The low-dose CT exam does not require intravenous contrast.

What can be detected with Low-Dose CT for Lung Cancer?

  • Lung cancer most commonly manifests as a noncalcified pulmonary nodule.
  • Computed tomography (CT) is superior to chest radiography for detecting pulmonary nodules.
  • Low-dose CT scans showing no noncalcified pulmonary nodules are regarded as negative results.
  • If solitary or multiple nodules are detected, recommendations for further procedures are made.

Should I be screened?
