DEXA Scan (Bone Mineral Density Exam)

Clermont Radiology - DEXA Scan (Bone Mineral Density Exam)

DEXA (Dual Energy X-ray Absorptiometry) examinations estimate the amount of bone mineral content in specific areas of your body. Two X-Ray energies allow the Radiologist to tell the difference between bone and soft tissue, giving a very accurate estimation of bone density.

Often confused with a nuclear medicine bone scan, a bone mineral density measurement with DEXA is painless, and requires no injections, invasive procedures, sedation, special diet or any other advance preparation. During a DEXA exam, the patient lies fully clothed on a padded table while the system scans one or more areas of bone (usually the lower spine or hip).

While DEXA uses x-rays, the radiation dose is less than during a chest x-ray. Each patient's bone density is plotted against the "normal" for a healthy young adult or against age matched control data.
