Digital X-ray radiogrammetry is a method for measuring bone mineral density (BMD). Digital X-ray radiogrammetry is based on the old technique of radiogrammetry. In DXR, the cortical thickness of the three middle metacarpal bones of the hand is measured in a digital X-ray image.

Digital radiography is a form of radiography that uses x-ray–sensitive plates to directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate cassette. [1] Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer ...

Digital X-ray radiogrammetry (DXR) uses BoneXpert to measure cortical bone quality on hand radiographs. This prospective study compared DXR and DXA results in children with high probability of secondary low bone quality, defined as DXA of the lumbar spine (DXA LS) Z -score ≤ − 2.0. One hundred one children underwent both DXA and DXR assessment.

Computed radiography (CR) is the most common method of producing digital radiographic images and the first technology that was commercially available. CR uses a storage phosphor that requires light input to release the trapped energy in the form of light that is proportional to the X-ray intensity. It is referred to as a photostimulable phosphor.
Mar 15, 2016 · Digital X-ray radiogrammetry (DXR) is a computer-assisted diagnosis technique for quantifying cortical hand bone mineral density (BMD) as well as the metacarpal index (MCI) in the metacarpal bones from radiographs.

Mar 30, 2016 · The digital X-ray radiogrammetry bone mineral density has been shown to correlate well with peripheral dual-energy X-ray absorptiometry measurements in studies of the forearm, the femoral neck in adults, and the lumbar spine and total body in children [10–13].
Similar to other countries, they work within the areas of radiography diagnostics (CT scans, magnetic resonance imaging, radiography, digital subtraction angiography), radiation therapy, radiation dosimeters and nuclear medicine.
