Peripheral Quantitative Computed Tomography

  • Chapter
Radiology of Osteoporosis

Part of the book series: Medical Radiology ((Med Radiol Diagn Imaging))

Abstract

Peripheral quantitative computed tomography (pQCT) at the forearm was introduced shortly after CT for medical imaging and several years before the development of spinal QCT (Ruegsegger 1974; Genant and Boyd 1977), as a volumetric extension to Cameron’s projectional technique for bone mineral measurements (Cameron and Sorenson 1963). Compared to single photon absorptiometry (SPA), the advantages of pQCT are obvious: separate assessment of trabecular and cortical bone and determination of true volumetric density instead of areal bone mineral density (BMD).
