The use of high-resolution peripheral quantitative computed tomography (HR-pQCT) to assess bone microarchitecture in clinical studies has continued to grow rapidly. Thus, there is an urgent need for guidance and consensus on the methods for and reporting of HR-pQCT imaging so that different studies can be compared to each other.
An important new position paper , published by a joint working group from the International Osteoporosis Foundation (IOF), the American Society for Bone and Mineral Research (ASBMR) and the European Calcified Tissue Society (ECTS), now addresses the need for standardization of techniques and terminology, provides guidance on interpretation and reporting of results, and discusses unresolved issues in the field.
Dr Nicholas Harvey, Professor of Rheumatology and Clinical Epidemiology at the University of Southampton, UK and Chair of the IOF Committee of Scientific Advisors, stated: "HR-pQCT is a powerful technology which provides novel insights into bone microarchitecture which are highly valuable to a broad range of bone-related research. These new guidelines, which are testament to the close collaboration between globally leading organizations in the bone field, provide direction on the technical aspects of HR-pQCT for use in the clinical setting, including best practices for acquisition and analysis of scans, as well as much needed guidance on the presentation and interpretation of results."
Specifically, the guidance provides:
Senior author, Dr Mary Bouxsein, Director of the Center for Advanced Orthopaedic Studies, Beth Israel Deaconess Medical Center and Professor, Department of Orthopedic Surgery, Harvard Medical School added: "The implementation of these recommendations as best practices will help to facilitate the comparison of results across studies by minimizing technical variation in scan acquisition and analysis. We expect that this will be of enormous benefit to clinical research in the bone field and will support the further advancement of HR-pQCT for a variety of clinical applications."
