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.
The radiographerâs role is to provide the physician. with an image of the chest that is diagnostic and aids. in the treatment of the patient. This cannot be accom-. plished satisfactorily without adequate knowledge of. chest anatomy, pathology and consistent positioning in. both the ambulatory and bedridden patient.
