摘　　要：作者分析了４７例先天性脊椎裂的ＭＲＩ表现并按主要ＭＲＩ表现和临床需要分为囊性或开口性脊椎裂（包括脂肪脊髓脊膜膨出、脂肪脊膜膨出、脊髓脊膜膨出、单纯后位脊膜膨出和皮毛窦，伴或不伴其他先天性疾病）、复杂性隐性脊椎裂（无体表体征但伴有低位圆锥、隐性脊膜膨出、脊髓空洞、脂肪瘤、皮样囊肿和椎体发育不良等）和单纯性隐性脊椎裂。对于囊性或开口性脊椎裂，ＭＲＩ不仅可确定有无脊髓膨出，还能显示椎管内伴发的其他先天性病变。对于隐性脊椎裂，ＭＲＩ能确定是否伴椎管内病变，而准确地区分复杂性和单纯性隐性脊椎裂。因此，ＭＲＩ有利于临床治疗，应成为先天性脊椎裂的首选检查方法。DependingupontheMRImanifestationsandclinicalrequirements,47patientswithspinabifidawereclassifiedintothreemajortypes,i、e、spinabifidaaperta(includinglipomeningomyelocele,lipomeningocele,meningomyelocele,meningoceleandpilonidalsinuswithorwithoutothercongenitallesions),complexspinabifidaoccultaassociatedwithlowconus,meningoceleocculta,syringomyelia,spinalipoma,dermoidcystandvertebraldysplasiaetalwithoutbodysurfacesignsandthesimplespinabifidaocculta.MRIwasdbletodetecteithermyeloceleortheassociatedcon-genitallesinosinspinabifidaapertaandwasalsoabletoaccuratelydistingiushcomplexspinabifidaoc-cultafromsimplespinabifidaoccultabydetectingthelesionsinthevertebralcanal.ThereforeMRIplaysmuchmoreimportantrolethantheotherexaminationmethodsinthetreatmentandshouldbethefirstchoiceandefectivediagnosticmethodforspinabifida.
