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.
20 studied the role of radiographers in identifying those patients with an abnormal mammogram which, in their opinion, needed further assessment, by placing a âred dotâ on the patients form indicating the site of the lesion. However, their sensitivity was low compared with that of the radiologists.
