      Most studies involving ultrasound techniques are devoted to the measurement of the propagation of sound through bone. Mass and architecture of bones can be determined by the velocity or speed of sound and the attenuation of the ultrasound wave in frequency or broadband ultrasound attenuation (BUA) [11,12]. The measurement of time-of-flight is almost restricted to the axial and circumferential propagation of the waves in bones to determine their geometry, elasticity and mineralization [13].

      There are two primary parameters in the QUS measurements that can be used for bone characterization: the broadband ultrasound attenuation (BUA) and the speed of sound (SOS). The BUA is an accepted indicator of trabecular bone status [11–14]. It is directly related to the connectivity and trabecular separation [7].

      However, in recent y, quantitative ultrasonography (QUS) of the proximal phalanges is a technique that has been used to assess bone status and fracture risk (Albanese et al. 2011; Baroncelli et al. 2006; Cepollaro et al. 2005; Halaba et al. 2005; Mussa et al. 2011; Wuster et al. 2000). There is evidence indicating that QUS measurements provide information not only on bone density but also on bone architecture and elasticity (Fuerst et al. 1995; Kaufman and Einhorn 1993; Njeh et al. 1997). Additionally, QUS is portable, relatively simple, non-invasive and does not expose the patient to ionizing radiation, in contrast to DXA and computed tomography (Baroncelli et al. 2008).

      These other factors most likely include microarchitectural parameters that are not assessed by densitometry techniques, such as elasticity, geometry or structure (Gluer et al. 1994). Quantitative ultrasound (QUS) methods have been developed in recent years for the indirect assessment of bone quality and skeletal status on the basis of a variety of experiences, suggesting that ultrasound parameters provide information not only about bone density but also about architecture and elasticity (Kaufman and Einhorn 1993; Njeh et al. 1997; Fuerst et al. 1995). The interest in this technology stems mostly from its practical advantages compared with conventional photon- or x-ray–based methods, i.e., it is relatively inexpensive, free of ionizing radiation and the scanning time is faster, so QUS can be a cost-effective diagnostic choice for osteoporosis screening.
