Objective To demonstrate the validity of volumetric QCT and dual energy X-ray absorptiometry( DXA )in bone mineral density (BMD) measurement and compare the difference in discriminating osteoporotic postmenopansal women with and without vertebral fracture. Methods One hundred and eighteen postmenopausal women [ mean age (62. 1 ± 7.0) years ] who received thoracolumbar radiographic examination were enrolled and divided into four groups (normal, osteopenia, osteoporotic and osteoporotic fractured group) also based on their BMD value of lumbar vertebra(AP-SPINE) measured by DXA: >x- 1s,x- 1s-x-2s,

In this paper,we analysed the plain film of spine and CT bone mineral density(BMD)of lumbar vertebral body in 63 Chinese osteoporotic women. There are 29 and 34 cases with and without fracture respectively in these patients. The average value of BMD in the fracture group was markedly lower than that of the non fracture group (P=0.0006).We suggested that 95mg/cm ̄3 may be taken as an appropriate fracture threshold for Chinese elderly women, There were 18 and 45 cases with and without heterogenous calcification respectively in these patients.A significant difference of BMD was found between the two groups(P
