Absorptiometry Definition & Meaning - Merriam-Webster
The meaning of ABSORPTIOMETRY is measurement of the amount of radiation absorbed (as by living tissue) especially to determine density.
Absorptiometry | definition of absorptiometry by ... - Medical …
Absorptiometry A technique used to assess bone mass, which measures the degree to which radiation emitted by a radioisotope is dissipated in a tissue. Types Single photon absorptiometry, dual X-ray absorptiometry
Absorptiometry - an overview | ScienceDirect Topics
Absorptiometry is a means of assessing BMC or density of various areas of the skeleton. Single-photon absorptiometry uses an iodine 125 source and is restricted to measuring BMC at the one-third and one-tenth distal radial sites of the forearm.

X Ray Absorptiometry - an overview | ScienceDirect Topics
The principle of X-ray absorptiometry is similar to that of photon absorptiometry: X-rays are attenuated in proportion to tissue density. The advantage of X-rays as a source was that it eliminated the need for radioactive isotopes and thus increased the ease of scanning and eliminated the need to replace the gadolinium source.
Absorptiometry | Journal of Radiation and Nuclear Medicine
Absorptiometry is a medical imaging technique used to measure the absorption of energy by tissues. It is used most commonly to measure bone mineral density, aiding in the diagnosis of osteoporosis and other bone-related diseases.
Dual-energy x-ray absorptiometry - Radiopaedia.org
2023年9月11日 · Dual-energy x-ray absorptiometry (DEXA or DXA) is a technique used to aid in the diagnosis of osteopenia and osteoporosis. Values are calculated for the lumbar vertebrae and femur preferentially, and if one of those sites is not suitable (e.g. artifact, patient mobility), or if there is a history of hyperparathyroidism, the forearm can be used 1.
