PhenX - spine - femur bone density by dual-energy x-ray absorptiometry protocol 170701

PhenX - spine - femur bone density by dual-energy x-ray absorptiometry protocol 170701
Steward:
PhenX
Definition:
The Framingham Osteoporosis Study Generation 3 Musculoskeletal Exam includes instructions for preparing the sample person for the scan, performing quality assurance procedures, and performing the scan of the hip and spine. Given that there are multiple manufacturers and models of dual-energy X-ray absorptiometry (DXA) machines (each with associated software), investigators must report the equipment they are using and cannot directly compare bone density measurements from different DXA machines (per the International Society for Clinical Densitometry (2007) and Bonnick, S. L. (2009)). Additionally, weekly scans using DXA phantoms are recommended as an independent assessment of system calibration. Studies that use more than one DXA machine should also implement a plan to monitor inter-scanner differences at baseline and at regular intervals during the study. Additionally, for studies involving more than one technician, an average precision error that combines data from all of the technicians should be used to establish the least significant change (LSC) and the precision error for the DXA facility (per the International Society for Clinical Densitometry (2007)). Lastly, the precision error for technicians should be evaluated periodically, such as after they have received training on the specific DXA machine, have completed DXA scans on about 100 patients, if there has been a change in their skill level, or if a new DXA system is used (per the International Society for Clinical Densitometry (2007)). Note: Manufacturers of DXA equipment are constantly striving to improve and update both their equipment and software with the latest technological advances. Hence, please refer to the DXA specifications for your model number to ensure that the level of information collected is compatible with the PhenX protocol. Given that the selected protocol uses a GE Lunar densitometer(c), the PhenX Skin, Bone, Muscle and Joint Working Group recommends that users of HologicTM densitometers find comparable protocols used by the National Health and Nutrition Examination Survey (NHANES). DXA measurement is complex and requires costly hardware, specialized software to analyze the DXA scans, rigorous quality control, specialized examiners, continuous equipment calibration and monitoring, and scan quality control monitoring. Although excerpts of the procedure manual for the Framingham Osteoporosis Study Generation 3 Musculoskeletal Exam (May 2008-2010) protocol are provided for informational purposes, investigators should review all facets of the protocol prior to undertaking DXA examinations in a study.
