Abstract:
Objective Toexploretheclinicaldiagnosisvalueofthehighfrequencycolordopplerultrasound(HFCDU)character-istiesofwristdamageinpatientswithrheumatoidarthritis(RA).Methods 78patientswithRA(RAgroup)werecollectedfrom June 2012 to December 2012 in the Affiliated Hospital of Inner Mongolia Medical University ,sonogram anatomy changes and syno-vial thickness of bilateral wrist were measured using colorul trasound ,meanwhile the respective data obtained from 50 healthy peo-ple undergoing physical examination(healthy control group);using color doppler flow imaging and color doppler energy ,synovial blood flow of artery resistance index (RI) and pulse index(PI) in synovial were measured and detected according to semi-quantitative method of alder ,and explord the correlations between RI and PI .Results (1)Among the 78 cases(156 joints) with RA ,join thy-drops(65 cases ,122 joints) ,inflammatory exudation(34 cases ,70 joints) ,synovium proliferation(78 cases ,153 joints) ,pannus(37 cases ,69 joints) and bony erosion(29 cases ,58 joints) were found.The thickness of synovial membrane of wrist in RA group was (3 .50 ± 1 .37)mm ,that in healthy control group was(1 .46 ± 0 .32)mm ,the different was statistically significant(P<0 .05) .(2) 64 cases among the 78 patients with RA were detected blood flow signals ,RI progressively reduced with blood flow grade the increas-ion which there was a negative correlation (r= -0 .79 ,P<0 .05);there was no significant correlation between PI and blood flow grade .(3) Ultrasound examination was more sensitive than rheumatoid factor (RF) and X-ray in detection rate of RA (P<0 .05) . Conclusion Ultrasound examination could detecte the pathological changes of wrist in patients with RA which is more sensitive than RF and X-ray ,and it could improve the detection rate of RA which contribute to early diagnosis and reasonable treatment for RA .
