Abstract

Bone densitometry has become an established tool for diagnosing and following up patients with disorders affecting the bone mineralization. The development of bone densitometry has certainly been driven by the need to overcome the inherent shortcomings of plain radiography for assessing bone density [17, 79]. Several studies show that the agreement between radiologists for the assessment of the bone mineral status based on radiographs of the spine is only moderate [30, 66]. This maybe even more a problem when one tries to assess changes in bone density based on conventional radiography. Semiquantitative methods such as Saville’s, Singh’s, or Jhamaria’s osteoporosis indices are of limited value, and some quantitative scores such as the Barnett-Nordin index at the spine do not really demonstrate a good correlation with bone density [6, 67, 68,112,114]. Therefore a number of methods for quantitatively assessing a person’s bone status to overcome the imperfections of plain radiography have been developed. With these methods a completely new terminology has evolved including various acronyms and definitions that are in part specific to some methods, or that are used for diagnostic purposes.
