Brachial Plexus Injury:The Diagnostic Accuracy of Magnetic Resonance Neurography and Its Consistency with Surgery
Objective To investigate the diagnostic efficacy of magnetic resonance neuroimaging(MRN)in brachial plexus injury(BPI)and evaluate its consistency with surgery.Methods The imaging data and operating records of 35 patients with BPI were reviewed retrospectively.The findings acquired at preoperative MRN were compared to those obtained at surgical exploration,with surgical exploration outcomes serving as the reference standard.Develop a categorization approach based on MRN signs and examine the consistency between MRN and surgical exploration findings.Results The positional assessment of nerve injury by MRN in 35 patients had a high concordance rate(91.4％)with surgical subtyping,and both concordance rates were good(82.9％).The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of MRN for the diagnosis of BPI were 92.7％,71.4％,90.3％,96.2％,and 55.6％,respectively.MRN classification by BPI did not differ significantly from surgical exploration results,and both had good consistency(kappa=0.743;kappa=0.686).Conclusion MRN can intuitively and accurately show the location,morphology,and signal of BPI.The neural classification method of MRN has good consistency with surgical exploration and is valuable for the diagnosis and treatment of BPI.
