Mammography uses a low-dose x-ray system to examine the breasts and aid in the early detection and diagnosis of breast diseases. It can detect breast mass that may not be palpable clinically, and detect calcifications in the breast which may indicate early cancers. Such calcifications usually cannot be identified by ultrasound examination. Screening mammograms are recommended annually for women who are 40 or older, and those who are at higher risk for breast cancer such as with a positive family history of breast cancers.
Dual-energy X-ray absorptiometry is a procedure that uses a low dose x-ray to measure bone mineral density. By imaging the spine, hip and wrist, the data obtained will be used to diagnose osteoporosis, estimate the risk of bone fracture and to assess response to treatment.
