“…The system is equipped with a convex 3.5 MHz transducer, which simultaneously detects B-mode ultrasound signals and unprocessed radiofrequency signals. Those which are analyzed by the machine's statistical algorithm (EchoStudio ® ; Echolight SRL) for each region of interest (ROI), taking into account the patient's ethnicity, age, sex and BMI and comparing them to a database of ~10,000 subjects (18,20,2426). The ROI for each patient included the usual sites for the diagnosis of osteoporosis: The lumbar spine (L1-L4 vertebrae approached from the abdomen) and the femoral necks.…”

“…However, the relative contributions of structural and material properties to the measured sound propagation characteristics remain challenging to discern [46]. QUS devices are portable, use non-ionizing radiation, and are increasingly applied in clinical studies [48,49] at distal sites of the skeleton (e.g., radius and tibia), which represent the same imaging target of HR-pQCT. With this respect, 3D descriptions of the local cortical porosity obtained from HR-pQCT could be combined with site-matched experimental measurements and numerical simulations of ultrasound propagation in long bones, to help elucidating the interplay between ultrasound and the cortical microstructure.…”

“…Studies investigating the association between the measurements of DXA and QUS revealed inconsistent results. While a number of studies showed a significant positive correlation between DXA and QUS ( Van Rijn et al, 2000 ; Di Mase et al, 2012 ; Falcini et al, 2000 ; Gonçalves et al, 2014 ; Hartman et al, 2004a ; Pluskiewicz et al, 2002 ; Sani et al, 2011 ; Sundberg et al, 1998 ; Xu et al, 2014 ; Bąk-Drabik et al, 2016 ; Catalano et al, 2017 ; Olszynski et al, 2016 ; Zuckerman-Levin et al, 2007 ; Mora et al, 2009 ; Weeks et al, 2016 ; Halaba et al, 2005 ; Catalano et al, 2013 ), others found a discrepancy between the measurements of the two methods ( Gianni et al, 2008 ; Halaba et al, 2005 ; Chong et al, 2015 ; Christoforidis et al, 2010 ; Christoforidis et al, 2011 ; Hartman et al, 2004b ; Williams et al, 2012 ; Alwis et al, 2010 ). This could be a result of the different QUS measurement sites or different patient categories investigated.…”

“…This could be a result of the different QUS measurement sites or different patient categories investigated. Only a limited number of studies used the phalangeal QUS ( Di Mase et al, 2012 ; Gonçalves et al, 2014 ; Pluskiewicz et al, 2002 ; Bąk-Drabik et al, 2016 ; Catalano et al, 2017 ; Olszynski et al, 2016 ; Halaba et al, 2005 ; Catalano et al, 2013 ) and only one study looked at the specific group of former preterm born children ( Gianni et al, 2008 ).…”
