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.
