Letter to the Editor: Refining the role of nerve ultrasound in Guillain-Barré syndrome diagnosis–opportunities for standardization and composite scoring
摘要
This letter discusses Mohamed et al.'s prospective study on nerve ultrasound (US) as a complement to nerve conduction studies (NCS) in early Guillain-Barré syndrome (GBS) diagnosis, noting excellent CSA-based accuracy at key sites (e.g., median nerve mid-forearm ≥ 0.0695 cm2: 100% sensitivity/specificity). It proposes critical next steps: incorporating proximal nerve segments into standardized protocols and developing composite US-NCS-clinical diagnostic scores to boost GBS precision and evaluation.
