The Applicative Study Of The Osteoporotic Diagnosis In Postmenopausal Women Using Lateral Spine Imaging By Dual Energy X-ray Absorptiometry

【Objective】We examined routine bone mineral density(BMD) and flash vertebral assessment(FVA) in postmenopausal women by dual X-ray absorptiometry (DXA),then compared the differences between BMD and vertebral fracture in diagnostic results of osteoporosis .In order to probe the clinical value of the rapid lateral spine imaging in diagnosing osteoporosis.【Methods】113 asymptomatic postmenopausal women were chosen in the study ,from 60-94yr,mean age was 71.7yr .We examined all the participants ' BMD of the anteroposterior spine, lateral spine ,left femoral neck and FVA by DXA. Vertebral fracture was assessed by visual semiquantitative assessment .The standard for osteoporosis is defined as either low BMD recommended by WHO or vertebral fracture .【Results】The FVA results showed that vertebral fractures were present in 37of 113 participants . According to WHO criterion for osteoporosis ,at spine or femoral neck site, 13 or 18 individiuals in 37 accorded with osteoporotic diagnosis ,furthermore there were 7or 3 catagmatic individiuals in normal BMD range . At spine or femoral neck site, 11 or 32 in 76 non-catagmatic individiuals accorded with osteoporotic diagnosis .There was no significant difference at either spine or femoral neck site in detecting osteoporosis at catagmatic group, 0.1
