A low-dose computed tomography (LDCT) scanning of the chest is the only recommended lung cancer screening test
LDCT is performed in individuals with a high risk of developing lung cancer because of their history of smoking or asbestos exposure as well as age. LDCT is a scanning technique that uses a combination of a special X-ray machine and sophisticated computers to provide several cross-sectional images of the body organs. In this test, an X-ray machine will use low doses of radiation to make detailed pictures of the lungs. Contrast material is not required when LDCT is used for lung cancer screening.
Lung cancer screening is performed by medical professionals that are involved in lung cancer care and belong to multiple specialties including pulmonology, radiology, interventional radiology, thoracic surgery, medical oncology, and pathology. During the examination, you will be lying on your back on the CT examination table with your arms raised over your head. The table will be moving slowly through the machine as you hold your breath for 5-10 seconds.
