Figure 6 A typical case: case 2. (A) Cervical spine magnetic resonance imaging (MRI) showed no apparent cervical spinal canal stenosis in segments C6/C7. (B) Coronal MRI of 3-dimensional fast-field echo with water-selective excitation (CMRI) showed disc herniation at the left C6/C7 level, with nerve root filling defects (red circle). (C) After pre-operative localization by CMRI imaging, insertion of a working cannula. (D) Exposure of the V-point (blue arrow). (E) Exposure of the protruding intervertebral disc (blue arrow). (F) Surgical specimen of the removed intervertebral disc. (G) Degenerated disc tissue for comparison. (H) Postoperative computed tomography image with appropriate windowing. (I) Postoperative CMRI showed good decompression of the right C7 nerve root (red circle). Vue PACS, v12.2.6, Philips.
