Abstract

This chapter provides an overview of the current densitometry techniques that are used in children. The strengths and limitations of each of the techniques are discussed. Dualenergy x-ray absorptiometry (DXA) is discussed only briefly, as the remainder of this book concentrates on this technique in detail. Table 1 provides a technical overview of costs, uses, precision, and radiation exposure associated with densitometry methods. Radiation doses associated with other imaging modalities and with natural background sources are provided for comparison in Table 2.
