摘要
目的 :分析常规腹盆部CT扫描中股骨头CT值与髋部定量CT(quantitative CT,QCT)测量中髋部骨密度值(bone mineral density,BMD)的相关性,并探讨股骨头CT值对髋部骨质疏松症的诊断价值。方法:前瞻性选取2021年6月1日至2022年1月20日因病情需要在某院进行非增强腹盆部CT扫描的176例患者,对扫描后的图像分别进行股骨头CT值和髋部BMD值测量。根据髋部T值及《中国定量CT(QCT)骨质疏松症诊断指南(2018)》将患者分为骨量正常组、骨量减少组及骨质疏松组3组。应用Pearson相关性检验分析股骨头CT值与髋部BMD值的相关性,应用配对t检验分析两侧股骨头CT值及BMD值的差异,应用方差分析不同骨质量组间的CT值差异,采用ROC曲线分析股骨头CT值对髋部骨质疏松症的诊断效能。结果:股骨头CT值与髋部BMD值有强相关性(r=0.696)且左侧股骨头CT值及左侧髋部BMD值均稍高于右侧。两侧股骨头的CT值显示骨质疏松组、骨量正常组、骨量减少组3组之间差异有统计学意义(P=0.000),骨量正常组CT值大于骨量减少组,骨量减少组CT值大于骨质疏松组。股骨头CT值及髋部BMD值均在41~50岁年龄段达到峰值,而后逐渐下降。股骨头CT值对髋部骨质疏松症的预测效能较高(左侧股骨头AUC=0.859,右侧股骨头AUC=0.846)。结论:股骨头CT值与髋部BMD值的相关性较好,且股骨头CT值对骨质疏松症具有较高的诊断价值。
Objective To analyze the correlation between femoral head CT values in routine abdominopelvic CT scanning and hip bone mineral density(BMD)values in hip quantitative CT(QCT)measurements,and to investigate the diagnostic value of femoral head CT values for hip osteoporosis.Methods Totally 176 patients undergoing non-enhanced abdominopelvic CT scanning at some hospital from June 1,2021 to January 20,2022 were selected prospectively,and femoral head CT values and hip BMD values were measured on the scanned images.The patients were divided into a normal bone mass group,a reduced bone mass group and an osteoporosis group according to hip T values and the"China Guideline for the Diagnosis Criteria of Osteoporosis with Quantitative Computed Tomography(2018)".Analyses were carried out for the correlation between femoral head CT values and hip BMD values,the difference between femoral head CT values and BMD values of the two sides with paired t-test,the difference of CT values between the three groups with ANOVA and the diagnostic efficacy of femoral head CT values for diagnosing hip osteoporosis with AUC curve.Results The values of femoral head CT and hip BMD had a strong correlation(r=0.696),which were slightly higher on the left than on the right.The three groups had statistically significant differences of femoral head CT values at two sides(P=0.000),which were ranked according to CT values as the normal bone mass group,the reduced bone mass group and the osteoporosis group.Femoral head CT values and hip BMD values both reached the peak at the age of 41 to 50 years,and then decreased gradually.Femoral head CT values behaved well in predicting hip osteoporosis,with femoral head AUC value being 0.859 on the left and 0.846 on the right.Conclusion The values of femoral head CT and hip BMD had a strong correlation,and femoral head CT values are valuable for diagnosing osteoporosis.
