Dual-frequency ultrasound technique minimizes errors induced by soft tissue in ultrasound bone densitometry.

30 Oct 2008 BACKGROUND: Most bone ultrasound devices are designed for through-transmission measurements of the calcaneus. In principle, ultrasound backscattering measurements are possible at more typical fracture sites of the central skeleton. Unfortunately, ... Read more...

Impact of trochanteric heterotopic ossification on measurement of femoral bone density following cemented total hip replacement.

29 Sep 2008 During a study of bone mineral density changes around cemented femoral implants, we recognized heterotopic ossification occurring regularly in a position anterior to the greater trochanter and proximal femur. The aim of this study was to describe ... Read more...

Changes in bone mineral status and bone size during pregnancy and the influences of body weight and calcium intake.

29 Sep 2008 BACKGROUND: Calcium may be mobilized from the maternal skeleton during pregnancy, which may be influenced by several factors. OBJECTIVE: The objective was to investigate changes in bone mineral status and size during pregnancy and to consider the ... Read more...

Technical information about 'Absorptiometry, Photon'

Definition: A noninvasive method for assessing BODY COMPOSITION. It is based on the differential absorption of X-RAYS (or GAMMA RAYS) by different tissues such as bone, fat and other soft tissues. The source of (X-ray or gamma-ray) photon beam is generated either from radioisotopes such as GADOLINIUM 153, IODINE 125, or AMERICUM 241 which emit GAMMA RAYS in the appropriate range; or from an X-ray tube which produces X-RAYS in the desired range. It is primarily used for quantitating BONE MINERAL CONTENT, especially for the diagnosis of OSTEOPOROSIS, and also in measuring BONE MINERALIZATION.
