摘要
目的评价双能X线吸收法测定腰椎骨密度时侧位的临床价值。方法178例女性患者(按年龄分组)接受腰椎后前位和侧位骨密度测定,以BMD表示骨密度值,以T值为标准判断骨量正常、骨量减少和骨质疏松,评价腰椎后前位与侧位T值对骨量减少程度的判断和骨质疏松诊断的差别。结果①各年龄组患者腰椎后前位BMD值均高于侧位值;②各年龄组患者腰椎后前位及侧位T值对骨量减少程度的判断有显著性差别;③当大于50岁时,腰椎后前位及侧位T值对骨质疏松诊断有显著性差别。结论腰椎侧位对女性患者骨量减少程度的判断和骨质疏松的诊断(>50岁)都有一定临床价值。
Objective To identify the clinical value of lateral view of lumber spinal measurement for the determination of BMD by using DEXA. Methods 178 patients (divided into groups by age)accepted anteriorposterior(AP) view and lateral view examinaiton of lumber spinal vertebrate for BMD. T value was used to determine normal, osteopenia and osteoporosis. The difference between AP view and lateral view for the determine of the extent of BMD decreasing and the diagnosis of osteoporosis by L-L4 was observed. Results ① BMD was higher in AP view than lateral view for all age groups; ②There was significant difference between AP view and lateral view for the extent of BMD decreasing for all age groups when the T value was used; ③There was significant difference between AP view and lateral view for the diagnosis of osteoporosis for 〉 50 groups when the T value was used ( P 〈 0.001 ). Conclusions Lateral view measurement was of some usefulness for both the determine of the extent of BMD decreasing and the diagnosis of osteoporosis for female patients( 〉 50 groups).
