Emphysema: Hyperaeration means that the lungs appear more radiolucent on chest x-ray and over expanded. This is due to enlargement of the airspaces caused by destruction of the walls of the alveoli (air sacs).
A radiographer works with medical imaging equipment (particularly X-rays) to create images of patients that a physician may use in diagnosing injuries and disease. They typically work in hospitals, large clinics or as part of a dedicated radiography business that sees referrals for these procedures.
Radiologic Technologists on the Medical Imaging Team. Radiologic technologists who perform imaging examinations are responsible for accurately positioning patients and ensuring that a quality diagnostic image is produced. They work closely with radiologists, the physicians who interpret medical images to either diagnose or rule out disease or injury.
