Reference diagram for nEMG puncture localization of RCPmi. (A) Pre-puncture, head and neck 3D-T1 sequence, sagittal view near midline RCPmi localization slice. (B) Pre-puncture, head and neck 3D-T1 sequence, axial view RCPmi localization slice. (C) Pre-puncture, head and neck 3D-T1 sequence, coronal view RCPmi localization slice. (D) Pre-puncture, head and neck 3D-T1 sequence, 3D perspective reconstruction localization slice. (E) Pre-puncture, head and neck 3D-T1 sequence, 3D body surface reconstruction localization slice. (F) Localization diagram of RCPmi puncture site on the subject. (G) Intraoperative C-arm X-ray sagittal localization diagram during puncture. (H) Patient condition during nEMG testing. (I) Preoperative nEMG examination puncture using methylene blue to stain RCPmi, immediately followed by posterior cranial fossa decompression surgery to verify puncture accuracy. Results show that the deep blue part is the left side RCPmi, accurately punctured. RCPmi rectus capitis posterior minor, EMG electromyogram.
