摘要
摘要目的探讨股骨头缺血性坏死早期诊断中磁共振成像应用价值.方法选取股骨头缺血性坏死５０例,均为我院２０１３年５月至２０１５年５月收治,在早期采用磁共振成像检查.结果选取的患者５０例,检出股骨头缺血性坏死３２例,有临床症状１７例,X线为阴性;５０例患者,共有股骨头６０个,X线无异常或骨质轻微异常改变、关节间隙正常、股骨头不变形者,应用MRI检查均呈异常表现.MRI以条带状或线样T１WI低信号、T２WI高信号为表现１８例;呈不规则形、斑片状、片状T１WI低信号、T２WI高信号股骨头２９个;呈小囊状T２WI高信号、T１WI低信号股骨头１３个.３０个为关节腔积液.结论MRI可对股骨头缺血性坏死早期显示,敏感性居较高水平,并可对坏死的分期和部位反映,发挥早期诊断作用,提供临床治疗的依据.关键词磁共振成像;股骨头缺血性坏死;早期诊断;应用价值AbstractObjectiveToinvestigatethevalueofmagneticresonanceimaginginearlydiagnosisofavascularnecrosisofthefemoralhead．Methods５０casesofavascularnecrosisofthefemoralheadweretreatedinourhospitalfromMay２０１５toMay２０１３,intheearlystagebymagneticresonanceimaging．Results５０patientswereselected,３２casesweredetectedwithavascularnecrosisoffemoralhead,１７caseswereclinicalsymptoms,５０caseswerenegative,６０caseswerefemoralhead,caseshadfemoralhead．MRItoaribbonorcordlikeT１WIlowsignalandhighsignalintensityonT２WIwasperformedin１８cases;isirregularandpatchy,T１WIlowsignal,T２WIhighsignalfemoralhead２９;afollicularT２WIhighsignalandlowsignalintensityonT１WIfemoralhead１３．３０forarticularcaviＧtyeffusion．ConclusionMRIcanbeusedforearlydiagnosisofavascularnecrosisofthefemoralhead,andithasahighsensitivity,andcanreflectthestageandloＧcationKoefynewcorrodssis．Magneticresonanceimaging;Avascularnecrosisoffemoralhead;Earlydiagnosis;applicationvalue中图分类号R５７５文献标识码B文章编号１００１－５３０２(２０１５)０９－０６３１－０１
