[Abstract]Objective：Toinvestigate thevalueofcontrast-enhancedmagneticresonanceneurography（ceMRN）combined with3Dreconstructiontechniqueinthediagnosisof brachialplexusnerveinjury.Methods：ThesurgicalandceMRNdata of37patientswithbrachialplexusnerveinjurywereretrospectivelyanalyzed，andtheacuracyofceMRNindiagnosingthe locationanddegreeofbrachialplexusnerceinjurywasanalyzed.Results：Comparedwith thesurgicalresults，thesesitvity， specificityandaccuracyofceMRNindiagnosinguppr trunk injuryof thebrachial plexuswere95.45%（63/6），77.78%（14/18） and 91.67%（77/84），those for middle trunk injury were 96.00% （48/50），83.33% （5/6）and 94.64% （53/56），and those for lower trunk injury were 95.56%（43/45），73.33%（11/15）and 90.00%（54/60），with K values of 0.747，0.739 and 0.721， respectively（all P <0.001）. The accuracy rate of ceMRN in diagnosing the degree of injury as types A and B was 83.33%（25/30），that for typeCwas92.31%（48/52），for type Dwas88.10%（37/42），andfortype Ewas91.89%（34/37）. Conclusion：ThecombinationofceMRNand3Dreconstructiontechniquehashighaccuracyinthediagnosisofbrachial plexus nerve injury.
