双能X线测定腰椎和股骨颈骨密度诊断骨质疏松症结果分析(1)
摘 要 目的：分析双能X线测定腰椎和股骨颈骨密度诊断骨质疏松症结果。方法：选2018年3月—2019年10月接诊的80例骨质疏松症患者，进行腰椎和股骨颈双能X线骨密度测定，比较不同部位骨密度测定结果及骨质疏松症的检出率。结果：所有年龄段患者腰椎骨密度测定结果均低于股骨颈(P<0.05)；腰椎骨密度测定对骨质疏松症的检出率高于股骨颈(P<0.05)。结论：腰椎双能X线骨密度测定能够更好的检出骨质疏松症，可作为优选检测部位。

ABSTRACT Objective： To analyze the results of dual energy X-ray absorptiometry of bone mineral density of lumbar spine and femoral neck to diagnose osteoporosis. Methods： Eighty cases of osteoporosis patients who were admitted to our hospital from March 2018 to October 2019 were selected to be measured by dual energy X-ray absorptiometry of bone mineral density of lumbar spine and femoral neck to compare the results of bone mineral density and the detection rate of osteoporosis in different parts. Results： Bone mineral density measurement results of lumbar spine in all age groups were lower than those of femoral neck(P<0.05)； the detection rate of osteoporosis by dual energy X-ray absorptiometry of lumbar spine was higher than that of femoral neck(P<0.05). Conclusion： The dual energy X-ray absorptiometry of bone mineral density of the lumbar spine can better detect osteoporosis， which can be used as the optimal detection site.

骨質疏松症在临床上较为常见，发病机制复杂，多因内分泌疾病、营养性疾病、长期制动以及部分药物长期使用等引起，多见于绝经后女性[1]。随着我国老龄化加剧，该病的发病率逐渐升高，已经成为严重影响中老年人群健康的常见病之一。临床上对于骨质疏松症以预防为主，早期发现能够降低治疗难度。骨密度测定是诊断骨质疏松症的常用手段，临床上用于骨密度测定的方法较多，包括X线、定量CT、定量磁共振成像、双能X线等，其中双能X线以其良好的测定效果在临床上应用较多[2-3]。有文献报道，不同检测部位能够影响骨密度测定结果[4]。本文报道采用双能X线测定腰椎和股骨颈骨质疏松症的检出率及影响因素。
1 资料与方法
1.1 一般资料
选择2018年3月—2019年10月接诊的骨质疏松症患者80例，均为女性，年龄为46～87岁，平均(72.19±8.13)岁，近1年内有月经紊乱史或处于绝经期，均签署知情同意书。排除①合并风湿、类风湿、强直性脊柱炎等其他骨科疾病者；②有激素类药物、抗癫痫药物长期用药史者；③合并糖尿病、甲状腺功能亢进等内分泌疾病者；④长期卧床者；⑤妊娠期或哺乳期女性。
1.2 方法
患者入院后即用Discovery-Wi型双能X线骨密度仪(美国Hologic公司生产)测定患者腰椎(腰1～腰4椎体)和股骨颈(右侧)骨密度。比较不同检查部位双能X线骨密度测定结果及不同检查部位骨质疏松症的检出率。
骨密度(T)=(测量值-骨峰值)/正常成人骨密度标准差。骨密度正常：T≥-1.0，骨密度偏低：-2.5
