【摘要】 目的:探讨早期强直性脊柱炎患者骶髂关节PDI表现,总结、分析其对早期AS的诊断价值。材料与方法:运用PDI检查31例经临床确诊AS的62个骶髂关节(病例组)和20例健康体检者的40个骶髂关节(健康对照组),超声探测骶髂关节区域的彩色血流并计算血流阻力指数(RI)。结果:病例组62个骶髂关节,其中有52个骶髂关节显示血流信号而且可以测到RI,RI平均值(0.53+0.07);健康对照组中,11个骶髂关节显示有血流,5个骶髂关节血流信号频谱多普勒测得RI平均值(0.86+0.08);另外6个血流信号在频谱多普勒上呈现为舒张期反相血流。结论:早期AS患者的骶髂关节内部血流增多,PDI可显示骶髂关节低速血流、为诊断早期AS提供了重要的参考依据,分析PDI发现的骶髂关节低速血流与定量超声测量法(QUS)测量骨密度的关系:当骶髂关节内部血流分级增多、骨含量降低程度可能越明显。PDI联合HLA-B27、RF、CRP的检测不但对诊断早期AS有很大帮助,还可为AS治疗效果做随访观察。更多还原

【Abstract】 Purpose: To explore the early ankylosing spondylitis sacroiliac joint PDI performance,summary,analysis of its value in early diagnosis of AS. Materials and Methods: PDI examination of 21 cases of 42 sacroiliac joints in the clinical diagnosis of AS( case group) 40 sacroiliac joints and 20 healthy subjects( healthy control group),color Doppler ultrasound detection of sacroiliac joint area and calculate the blood flow resistance index( RI). Results: there were 42 sacroiliac joints,of which there are 37 sacroiliac joints show blood flow signal,wherein the 35 sacroiliac joints can be measured up to RI,the average value of RI( 0. 53 + 0. 07),the other 9 blood flow signals in the spectrum of diastolic reverse flow Doppler show; the healthy control group,11 of sacroiliac joint display there is blood,5 spectrum of sacroiliac joint blood flow signal Doppler measured the average value of RI( 0. 88 + 0. 08); the other 6 blood flow signals in the spectrum appears diastolic reversed blood flow Doppler. Conclusion: Early AS patients with sacroiliac joint internal blood flow increased,PDI can display thesacroiliac joint flow,provides important reference basis for the diagnosis and observation ofcurative effect analysis of early AS,PDI found that low flow of sacroiliac joint and quantitative ultrasound measurement( QUS) relationship between the measurement of bone mineral density: when the sacroiliac joint internal flow grading increased,decreased the content may be more obvious degree of bone. PDI joint HLA-B27,RF,CRP testing for early diagnosis of AS is not only of great help,but also for the treatment of AS do follow-up observation.更多还原
