Central dual-energy X-ray absorptiometry (DXA) is the gold standard for non-invasive measurement of bone mineral density (BMD). Using this value and subject demographics, DXA software calculates T-scores and Z-scores. Professional society guidelines for the management of osteoporosis are based on T-scores and Z-scores, rather than on the actual BMD value.(More)
OBJECTIVES To examine data from advanced cancer patients and their oncologists regarding patient age-related differences in patient and oncologist perspectives on involvement of primary care physicians (PCPs) in aspects of cancer management.
