Cross-calibration, Least Significant Change and Quality Assurance in Multiple Dual-Energy X-ray Absorptiometry Scanner Environments: The 2019 ISCD Official Positions

The ISCD periodically holds Position Development Conferences (PDCs) in which a panel of experts make recommendations based on reviews of scientific literature by specific task forces.  In 2019 the PDC Cross Calibration Task Force convened to assess calculation of least significant change (LSC) with multiple dual-energy X-ray absorptiometry (DXA) use.  The outcome of this PDC was the 2019 Official Positions of the ISCD regarding Cross-Calibration of DXA.  This activity aims to provide learners with the most current, evidence-based practice guidelines for assessing skeletal health so they may begin utilizing them in their clinical practice. 

Clinicians must be familiar with the known differences in BMD calibrations between manufacturers, as well as different scanners within a particular manufacturer’s product lines.  They must also be aware of differences in calibration within scanners of the same make and model, or with differences in software.  Clinicians must be familiar with the 2019 ISCD Official Positions related to cross-calibration so they know how to implement these best-practice guidelines in  their practice-setting to assure the precision error of the exam does not exceed the expected skeletal response to treatment, nor the validity of the scans.

This activity consists of a journal article and a series of questions that will allow you to engage in the most up-to-date research and practice guidelines from the 2019 ISCD Official Pediatric Positions.
