Dual-energy X-ray absorptiometry is the most widely used and most thoroughly studied bone density measurement technology. The DXA scan is typically used to diagnose and follow osteoporosis , as contrasted to the nuclear bone scan , which is sensitive to certain metabolic diseases of bones in which bones are trying to heal from infections ...
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

A bone scan or bone scintigraphy / s ɪ n ˈ t ɪ ɡ r ə f i / is a nuclear medicine imaging technique used to help diagnose and assess different bone diseases. These include cancer of the bone or metastasis, location of bone inflammation and fractures (that may not be visible in traditional X-ray images), and bone infection (osteomyelitis).
CT can better demonstrate the typical "ground glass" appearance, which is a highly specific radiological finding, while MRI can show cystic areas with fluid contents. [15] A bone scan uses radioactive tracers, which are injected into your bloodstream. The damaged parts of bones take up more of the tracer, which show up more brightly on the scan.
The measurement of regional bone metabolism is critical to understand the pathophysiology of metabolic bone diseases.. Bone biopsy is considered the gold standard to quantify bone turnover; however, it is invasive, complex and costly to perform and subject to significant measurement errors.
Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...

More images: Linear fracture Parallel to the bone's long axis more images: Transverse fracture At a right angle to the bone's long axis May occur when the bone is bent, [37] and snaps in the middle. Oblique fracture Diagonal to a bone's long axis (more than 30°) more images: Spiral fracture or torsion fracture
