As an emerging alternative to current radiation-based bone densitometry techniques, there is a growing interest in the use of quantitative ultrasound (QUS) measurements for the noninvasive assessment of fracture risk in the management of osteoporosis. However, there are also a multiplicity of technologically different QUS devices available on the market and, so far, no study has compared heel a...

PURPOSE Efforts for the early detection of bone loss and subsequent fracture risk by quantitative ultrasound (QUS), which is a non-invasive, radiation free, and cheaper method, seem rational to reduce the management costs. We aimed in this study to assess the probable correlation of speed of sound (SOS) values obtained by QUS with bone mineral density (BMD) as measured by the gold standard meth...

PURPOSE To assess bone mineralization in adolescents with bone tumors at remission using quantitative digital ultrasound (QUS) and dual-energy x-ray absorptiometry (DEXA), and to compare the bone mineralization values obtained by both methods. METHODS Patients studied were 36 adolescents (21 boys, 15 girls) who had completed treatment of a bone tumor at the University Hospital of the Universi...

BACKGROUND Osteoporotic fractures are a major health problem among postmenopausal women. A significant proportion of subjects with low bone density are currently undiagnosed. Peripheral devices can be used for osteoporosis diagnosis, but their role in long-term monitoring of skeletal changes is unclear. The current study evaluated the ability of quantitative ultrasound (QUS) measurements to fol...

BACKGROUND AND AIMS Quantitative ultrasound (QUS) was investigated to monitor bladder cancer treatment response in vivo and to evaluate tumor cell death from combined treatments using ultrasound-stimulated microbubbles and radiation therapy. METHODS Tumor-bearing mice (n=45), with bladder cancer xenografts (HT- 1376) were exposed to 9 treatment conditions consisting of variable concentrations...

OBJECTIVE To analyze the main factors that influence bone mass in children and teenagers assessed by quantitative ultrasound (QUS) of the phalanges. DATA SOURCE A systematic literature review was performed according to the PRISMA method with searches in databases Pubmed/Medline, SciELO and Bireme for the period 2001-2012, in English and Portuguese languages, using the keywords: children, teen...

Materials and Methods: This study included 116 postmenopausal women attending Adnan Menderes University Family Medicine Clinic in Aydin. Bone density was measured at the calcaneus using QUS and at lumbar spine and femoral neck with DXA. Receiver operating characteristic analysis was carried out to determine the best sensitivity and specificity for QUS T-scores for comparison with the gold stand...

ionizing radiation makes QUS a good screening tool to diagnose low bone density at the community level and supports the work done by Sharma et al.[1] Diagnosis of osteoporosis using QUS is practical and economical at the community level. This early diagnosis of osteoporosis would facilitate early initiation of pharmacotherapy and secondary preventive measures using patient education and physica...

PURPOSE This study demonstrated the ability of quantitative ultrasound (QUS) parameters in providing an early prediction of tumor response to neoadjuvant chemotherapy (NAC) in patients with locally advanced breast cancer (LABC). METHODS Using a 6-MHz array transducer, ultrasound radiofrequency (RF) data were collected from 58 LABC patients prior to NAC treatment and at weeks 1, 4, and 8 of th...

Dual-energy X-ray absorptiometry (DXA) is commonly used in the care of patients for diagnostic classification of osteoporosis, low bone mass (osteopenia), or normal bone density; assessment of fracture risk; and monitoring changes in bone density over time. The development of other technologies for the evaluation of skeletal health has been associated with uncertainties regarding their applicat...
