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.
Nationwide, there are more than 180,000 radiographers. Career mobility for radiographers is excellent. With further education or experience, opportunities exist for advancement in education, management and additional imaging modalities. Nationwide, the starting salary for a radiographer is between $30,000 and $35,000.
