standsFor Low-dose Spiral Computed Tomography
conceptDescription 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 scans can reveal lung abnormalities the size of a grain of rice.
aka helical CT scan
