DXA scanning

DXA scanning

Dual X-ray absorptiometry scanning, a technology of bone densitometry used to measure bone mineral density as a means of assessing the degree of OSTEOPOROSIS and the risk of trouble form it. Modern DXA equipment can perform the scan in a few seconds.

DXA Scanning. A whole body scan was performed for each subject with a DXA fan beam equipment (Hologic QDR4500 Explorer, Massachusetts, USA).
Anthropometry was initially conducted followed by DXA scanning.
Of note, the FRAX scores were recalculated for all participants using the empirically determined height and weight data obtained during DXA scanning. These "corrected" scores were used in the final data analysis.
Initially, 47 patients fulfilling the criteria were registered, but 22(46.8%) were excluded as 2(4.2%) were pregnant, 11(23.4%) had been on steroids and 9(19%) declined DXA scanning. The final sample stood at 25(53.2%) patients.
(1) Reflecting briefer prior recommendations from the European AIDS Clinical Society (EACS), (2) the new guidelines endorse the simple Fracture Risk Assessment Tool (FRAX) without DXA scanning for HIV-positive men 40 to 49 years old and for premenopausal women 40 or older (Figure 1).
To ensure consistent and reproducible positioning, the DXA operator manually assisted participants in order to: 1) straighten the head, neck and torso parallel to the long-axis of the scan bed; 2) position the shoulders and pelvis perpendicular to the long-axis of the scan bed; 3) place both arms in pronation by their side; 4) place legs at shoulder width with 45[degrees] internal rotation; and 5) fixate feet together using strapping tape to minimise incidental movement and for the participants comfort, within the DXA scanning zone (Figure 1).
US experts on HIV and bone disease recommend DXA scanning (a painless test like an x-ray) for all HIV-positive people over 50 years old.10 The researchers who conducted this HIV/HCV study believe their findings confirm that recommendation for people with HIV and for those with both HIV and HCV.
Key Words: Menopausal symptoms Osteoporosis DXA scanning.
Before beginning GFD, the BMD of the lumbar spine and femoral neck was measured by DXA scanning (Hologic; Bedford-MA) at Molinette Hospital, Turin, Italy.
Pickhardt and his colleagues evaluated CT-derived BMD assessment and compared it against DXA scanning of the hips and spine by identifying 1,867 adults who had undergone the two types of scanning within a 6-month period during the 10-year study interval.
2) Identification of women at high risk of fractures, meaning that treatment or further investigation using DXA scanning can be initiated.
If laboratory evidence suggests osteomalacia, clinicians can consider delaying DXA scanning until 25(OH)D levels are greater than 12-20 ng/ml.
