Abstract: ［Abstract］ Objective〖HTSS〗To explore the diagnostic value of quantitative ultrasound(QUS) and dual energy X-ray absorptiometry(DXA) in detecting bone mineral density(BMD) in menopausal women with postmenopausal osteoporosis and chest-costal joint pain.
〖HTH〗〖WTHZ〗Methods〖HTSS〗A total of 260 menopausal women with chest-costal joint pain who underwent health examination were selecded as the sbjects of study. All subjects were monitored by dual energy X-ray absorptiometry(DXA) as group B and QUS as group A. The accuracy, sensitivity and specificity of DXA were compared between the two groups according to the gold standard. The diagnostic value of QUS was analyzed in postmenopausal women with osteoporosis and chest-costal joint.
〖HTH〗〖WTHZ〗Results〖HTSS〗 52 cases of osteoporosis were detected in group B. There was significant difference in bone mineral density between different age groups(P＜0.05). 48 cases were detected in group A. There was significant difference in bone mineral density between different age groups(P＜0.05). The sensitivity, specificity, positive predictive value and negative predictive value of group A were 92.31%, 100%, 97.22% and 96.10%, respectively.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗There is a certain relationship between Sternocostal joint pain and osteoporosis in menopausal women.QUS has good sensitivity and specificity in the diagnosis of menopausal women with osteoporosis and chest-costal joint pain. It has a high coincidence rate and positive predictive value in clinical application.
