Scope Note
method of in vivo bone densitometry based on transmission of high energy photons, typically utilizing an I-125 source and NaI scintillation detector; newer, dual photon methods overcome variance due to differences in surrounding fat and other soft tissue.

Facts (generated by robot; please edit if you find it inaccurate)
- It is suggested that photon absorptiometry is a simple, sensitive, and reliable technique for assessment and follow-up of the bone mineral content in a host of disorders associated with bone demineralization.
- The measurement of bone mineral by photon absorptiometry is a relatively new technique, which is rapidly gaining acceptance.
- Of these, photon absorptiometry is more widely tested clinically and allows studies of predominantly cortical or trabecular bone sites and total skeletal calcium.
- Single photon Absorptiometry is covered as indicated in Medicare Coverages Issues Manual, 50-44.
