Although treatable, it is difficult to diagnose. The purpose of this study was to evaluate the diagnostic performance and abnormalities of plexus via quantitative multisequence magnetic resonance neurography (MRN) for CIDP.MethodsBrachial and lumbosacral (LS) plexus of 37 CIDP patients and 37 age- and gender-matched controls were examined by using multisequence MRN. Nerve diameter, nerve-to-muscle T2 signal intensity ratio (nT2), contrast-enhanced ratio (CR), fractional anisotropy (FA), and apparent diffusion coefficient (ADC) were determined in both plexus, and tractographies were performed. The disease histories and the Inflammatory Rasch-built Overall Disability Scale (I-RODS) questionnaire scores were documented before MRI scans.ResultsThe sizes of nerve roots were larger in CIDP (p < 0.01). CR, nT2, and ADC were significantly higher, while FA was lower in CIDP than in controls (p < 0.01). FA had the highest sensitivity (0.809) and area under the curve (AUC) (0.925), while the highest specificity was 0.961 for CR in single parameters. The combination of FA and CR has the highest sensitivity, specificity, accuracy, and AUC in the LS plexus. CR only had a weak correlation with nT2 (p < 0.05). ADC and diameter had a positive correlation with nT2, and the diameter and nT2 had a negative correlation with FA in CIDP (p < 0.05). FA had a negative correlation with the duration in the CIDP (r’s = −0.404, p < 0.05). There was no significant correlation between the I-RODS scores and MR multiparameters (p < 0.05).ConclusionMultisequence MRN possesses a high diagnostic performance in the LS plexus. Sampling perfection with application-optimized contrasts using different flip angle evolutions (SPACE) combined with DTI and contrast enhancement serves as a recommended composite protocol for CIDP.https://www.frontiersin.org/articles/10.3389/fnins.2021.649071/fullmagnetic resonance neurographydiffusion tensor imagingPolyradiculoneuropathychronic inflammatory demyelinatingplexuscontrast |
