Bone Densitometry scanning, also called dual-energy x-ray absorptiometry (DXA or DEXA) or Bone Density Scan, is an enhanced form of x-ray technology that is used to measure bone loss. DEXA is today's established standard for measuring bone mineral densitometry (BMD).
Routine x-ray exams use ionizing radiation to create images of various parts of the human body. The amount of radiation used in x-ray exams depends on the type of exam being performed. However, the technologists and doctors working with x-rays have been trained to use as little radiation as possible when performing your exam. The benefits of gaining information from your exam are greater than the small risks of any harm.
Magnetic Resonance Imaging, or MRI, is a painless, diagnostic test that allows radiologists to see inside some areas of the body, which cannot be seen using conventional x-rays. This imaging method produces a series of cross-sectional pictures. Physicians can detect many conditions in earlier stages improving prognosis.
