Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DXA is today's established standard for measuring bone mineral density (BMD).
Are used when the patient has no signs or symptoms.
Are used when signs or symptoms have been found.
Calcium affects the scan and analyzes the patient's number to appear osteoporotic. Diagnosing a patient with osteoporosis the condition of weak and brittle bones, depending on their provider can place them on unnecessary medications.
Contrast and radionuclides affect the DXA scan and analyzes the patient's number to appear osteoporotic. Diagnosing a patient with osteoporosis the condition of weak and brittle bones, depending on their provider can place them on unnecessary medications. Therefore, making sure this is free from their system ensures the proper diagnosis of our DXA patient population.
The DXA machine sends a thin, invisible beam of low-dose x-rays with two distinct energy peaks through the bones being examined. One peak is absorbed mainly by soft tissue and the other by bone. The soft tissue amount can be subtracted from the total and what remains is a patient's bone mineral density.
DXA machines feature special software that compute and display the bone density measurements on a computer monitor.
Bone density tests are a quick and painless procedure.
Routine evaluations every two years may be needed to see a significant change in bone mineral density, decrease or increase. Few patients, such as patients on high dose steroid medication, may need follow-up at six months.
