A CT scan is a medical diagnostic procedure that uses X-rays to produce detailed images of the internal structure of the body. A full-body CT scan, also known as a whole-body CT scan, is a diagnostic test that uses X-rays to produce high-resolution images of the entire body, from head to toe.
During the exam, the patient lies on a table that slowly moves through a doughnut-shaped tube containing the X-ray equipment. X-rays are emitted from various angles as the table moves through the tube, and X-ray detectors capture the images used to create detailed images of the body's internal organs, bones, and soft tissues.
Whole-body CT scans are useful for diagnosing a wide variety of medical conditions, including cancer, heart disease, lung disease, liver disease, and other serious medical problems. However, due to exposure to ionizing radiation during the exam, whole-body CT scans are only performed when medically necessary.
