Bone Density - DEXA

DEXA Scan stands for Dual Energy X-Ray Absorptiometry, and it is a screening to assess bone mineral density to detect the presence of osteoporosis in men and women with particular risk factors. The technology works by measuring the amount of x-rays that are absorbed by the bones in your body. Two x-ray energies allow the machine to differentiate between bone and soft tissue, providing a very accurate estimation of bone density. The radiologist will produce a report for your physician based on the bone density measurements and your medical history. The test is one of the most accurate ways to diagnosis Osteopenia or Osteoporosis. Osteoporosis is a debilitating disease that affects millions of people every year. However, early detection of this disease can lead to effective treatment and prevent fractures in the future. Bone density examinations are comfortable, fast and safe. Patients typically spend only minutes reclining fully-clothed on the densitometer. Radiation exposure is very low (equivalent to 1/20th of the dosage received in a normal chest x-ray). A certified technician is with the patient at all times, and results are available quickly. Many factors affect bone strength, including heredity, diet, cigarettes, alcohol, menopause, certain drugs such as Prednisone, excercise and gastrointestinal disorders. Bone mass measurement should be obtained in every woman who has had a fracture or any of the above predisposing factors.  Bone density scans are performed in the St. Mary Breast Center.
