The Specific Sagittal Magnetic Resonance Imaging of Intradural Extra-Arachnoid Lumbar Disc Herniation
Figure 1
Preoperative MRI of the lumbar spine: (a) sagittal plane T2-weighted image. (b) Axial plane T2-weighted image. The ventral dural line was divided such that disc herniation existed between the two lines (black arrow) (a). The border of cauda equina and disc herniation was unclear (b).
