A Low-Dose CT Scan for lung cancer uses computed tomography (CT) to offer a low dose of X-rays, useful in the early detection of lung cancer. Lung cancer screening with a low-dose CT scan of the chest has been shown to be beneficial in high-risk patients.
In a CT scan, an x-ray beam moves in a circle around the patient’s body. It takes many images, called slices, of the lungs and inside the chest. A computer processes the images and displays them on a monitor. Contrast dye may be injected to highlight structural changes in the lungs and improve image quality.
Patients meeting these criteria should be screened:
The physician who orders the lung cancer screening will receive a report after the test. If the results indicate an abnormality, additional tests may be ordered. These include:
