摘    要:
目的:探讨定量超声诊断早期类风湿性关节炎(RA)病人骨量变化的临床应用价值。方法:采用跟骨超声仪测量早期RA病人30例及与其相匹配的健康人30例的双足跟骨,主要诊断参数包括宽带超声振幅衰减(BUA)、超声传导速度(SOS)和超声硬度指数(STI),对两组的测量参数进行比较,并同时分析RA者骨质疏松发生率。结果:RA组BUA和STI明显低于对照组(均P〈0.01),差异有显著性;而SOS和OP发生率与对照组比较差异均无统计学意义(均P〉0.05);两组左右跟骨的BUA、SOS及STI比较差异均无统计学意义(P〉0.05)。RA病人中活动组BUA及STI值显著低于非活动组(均P(0.01),SOS两组间比较差异无显著性(P〉0.05)。结论:跟骨定量超声BUA测值减低可反映早期RA骨量丢失的程度及评价疾病的活动性。STI作为骨质量的综合评价指标,对早期RA病人的骨量丢失也有一定的意义。

Abstract:
Objective:To investigate the clinical application value of quantitative ultrasound that was used to diagnose bone quality changes in patients with early rheumatoid arthritis (RA).Methods:Broadband ultrasound attenuation (BUA),Speed of sound (SOS) and Stiffness index (STI) were measured by quantitative ultrasound in 30 RA patients and the results were compared with age-,sex-,BMI-marched healthy people.Meanwhile,analyzing the incidence of OP in patients with early rheumatoid arthritis.Results:BUA and STI in R...
Keywords:Rheumatoid arthritis  Quantitative ultrasound  Bone quality changes  Osteoporosis
