In lung cancer screening, individuals who have a high risk of developing lung cancer but no signs or symptoms of the disease undergo low-dose computed tomography (LDCT) scanning of the chest.
The type of low-dose CT scan that is recommended for lung cancer screening is a newer form of CT scan known as a low-dose spiral or helical CT scan. The low-dose spiral CT scan continuously rotates in a spiral motion and takes several 3-dimensional X-rays of the lungs. These X-rays are very detailed and can show early-stage lung cancers that may be too small to be detected by a traditional X-ray. Traditional X-rays can identify lung cancers the size of a dime, whereas low-dose spiral CT ...
