2013 Position Development Conference on Bone DensitometryExecutive Summary of the 2013 International Society for Clinical Densitometry Position Development Conference on Bone Densitometry
Introduction
The International Society for Clinical Densitometry (ISCD) is a nonprofit professional organization dedicated to the advancement of assessment of musculoskeletal health, particularly (but not limited to) bone densitometry. A major focus of the Society is the development of guidelines and establishment of standards for bone densitometry, assessment of fracture risk, and other aspects of musculoskeletal measurement. The Society conducts Position Development Conferences (PDCs) every 2–3 yr to develop guidelines and standards (expressed as Position Statements) for new technologies used to assess musculoskeletal health and fracture risk and to update older guidelines and standards as new data become available. The ISCD Official Positions are widely used by clinicians and densitometry technologists as a reference regarding the indications for, acquisition of, and interpretation and reporting of measures of musculoskeletal health and incorporation of those measures into fracture risk assessment. The curricula of the densitometry educational courses provided by ISCD are largely based on these Positions.
The ISCD PDC process is designed to summarize and use the best scientific evidence available to develop and update Position Statements regarding musculoskeletal assessment. Because musculoskeletal assessment technologies are evolving, clinically important issues are sometimes addressed in the absence of robust evidence and are, thus, largely based on expert opinion. However, the PDC process grades and highlights the limitations of the available evidence pertinent to each Statement and indicates where additional research is needed to improve the scientific evidence on which Positions are based and to resolve areas of ambiguity and controversy.
Position Statements from prior PDCs held in 2001, 2003, 2005, 2007, and 2010 have been published 1, 2, 3, 4, 5, 6. The most recent PDC was held in Tampa, FL, March 21 through March 23, 2013. This article describes the methodology of this PDC and the results from the topics regarding indications for bone densitometry, indications for vertebral fracture assessment (VFA), and use of young reference databases to calculate bone densitometry T-score values. A subsequent article in this issue reports the results of the PDC regarding the indications for, acquisition of, and interpretation and reporting of body composition analysis studies using dual-energy X-ray absorptiometry (DXA).

Methodology
Potential topics for the 2013 ISCD PDC were solicited from the ISCD Board of Directors (BOD), Executive Committee, and members of the Scientific Advisory Committee. Candidate topics were then ranked in order of importance. Body composition analysis was nearly unanimously identified as a critically new application of DXA requiring new guidelines and standards. Three other topical areas in which the ISCD already has Official Positions (1) were chosen to be updated because of new data that had
Acknowledgments
As was true of prior PDCs, the 2013 ISCD PDC was possible only through the extensive voluntary efforts of large numbers of individuals, notably the clinical and scientific experts who donated countless hours over the past 18 mo as Task Force chairs, Task Force members, or Expert Panel members. The ISCD wishes to acknowledge and thank these individuals for their extraordinary service. Additionally, the staff of ISCD plays a crucial role organizing the logistics and infrastructure of these
