摘　　要：目的:探究原发性骨质疏松症诊断中3.0T磁共振基于回波不对称和最小二乘估计定量序列的水和脂肪迭代分解(IDEAL-IQ)技术应用价值。方法:选2022年1月~2023年12月本院收治的80例骨科住院患者,均接受双能X射线骨密度检查、3.0T磁共振IDEAL-IQ技术检查,根据不同骨密度检查结果将其分为骨量正常组、骨量降低、骨质疏松组,比较其IDEAL-IQ中脂肪分数(FF)值检出情况,分析FF值与其骨量之间相关性。结果:骨质疏松组FF值水平较骨量正常组、骨量降低组高(P<0.05),骨量降低组FF值水平与骨量正常组相近(P>0.05);FF值与双能X射线骨密度检查结果显著负相关(r=-0.611,P<0.001);经受试者操作特征曲线分析显示,FF对原发性骨质疏松症诊断曲线下面积为0.831,最佳诊断截断值为76.63,灵敏度、特异度分别为71.43%、96.34%。结论:对原发性骨质疏松症患者诊断中,3.0T磁共振IDEAL-IQ结果FF值与其骨密度水平负相关,受试者操作特征曲线分析FF值对该病具有良好诊断效能。Objective:To explore the iterative decomposition of water and fat with echo asymmetry and least-squares estimation quantitation sequence(IDEAL-IQ)in the diagnosis of primary osteoporosis using the least squares estimation method of 3.0T magnetic resonance asymmetric echoes.Methods:80 hospitalized orthopedic patients in our hospital from January 2022 to December 2023 were selected,all of whom underwent dual energy X-ray bone density examination and 3.0T magnetic resonance IDEAL-IQ technology examination.They were divided into normal bone mass group,decreased bone mass group,and osteoporosis group based on different bone density examination results.The detection of FF value in IDEAL-IQ was compared,and the correlation between FF value and bone mass was analyzed.Results:The results showed that the FF value level in the osteoporosis group was higher than that in the normal bone mass group and the decreased bone mass group(P<0.05),while the FF value level in the decreased bone mass group was similar to that in the normal bone mass group(P>0.05);The FF value was significantly negatively correlated with the results of dual energy X-ray bone density examination(r=-0.611,P<0.001);The receiver operating curve(ROC)analysis showed that the area under the diagnostic curve(AUC)of FF for primary osteoporosis was 0.831,the optimal diagnostic cutoff value was 76.63,and the sensitivity and specificity were 71.43%and 96.34%,respectively.Conclusion:In the diagnosis of primary osteoporosis patients,the FF value of 3.0T magnetic resonance IDEAL-IQ results is negatively correlated with their bone density level.ROC curve analysis of FF value has good diagnostic efficacy for this disease.
