The Study of the Earlier Period Diagnostic Criterion and Curative Effects of Osteoporosis by QCT

Objective To study the earlier period diagnostic criterion of osteoporosis by QCT(quantitative computed tomography) and observe osteoporopsis curative effect.Methods Use SIEMENS SOMATOM quantitative CT and its BMD measure software to scan of the the second,third and fourth lumbar vertebral for BMD in healthy subjects and moreover mensurat AKP,blood calcium and the other bone metabolize index;And link the other hospital's result to study the earlier period diagnostic criterion of osteoporosis by QCT;Regularity cure the osteoporosis subjects for three months,and then observe their BMD's change by QCT.Results The peak values of BMD by QCT mensurating are different from that mensurated by DEXA.Their max values are about 20 years old.It can measurate in three months the obvious variety of the BMD after three months of regular treatment in osteoporosis subjects.Conclusion The QCT can observe in shorter time the variety of the BMD.The advantages of the curative effect of the QCT monitors is obvious;The earlier period diagnosis of osteoporopsis can be realized by observing the BMD's change from two points.
