Sagittal thecal sac angle. Thick-slab 20-mm coronal MIP image from a 3D SHINKEI acquisition (A) obtained at a sagittal angle of 16° (B) optimally demonstrates all the lumbar nerve roots (arrows, A) from their origin to the maximum length. Deg indicates degree.
- Fig 2.
Sagittal femoral nerve angle. Thick-slab 20-mm coronal MIP image from a 3D SHINKEI acquisition (A) obtained at a sagittal angle of 29° (B) optimally demonstrates bilateral femoral nerves (arrows, A) from their origin to the maximum length across the inguinal ligaments. Deg indicates degree.
- Fig 3.
Sagittal sciatic nerve angle. Thick-slab 20-mm coronal MIP image from a 3D SHINKEI acquisition (A) obtained at a sagittal angle of −9.6° (B) optimally demonstrates the bilateral sciatic nerves (arrows, A) from their origin to the maximum length. Deg indicates degree.
- Fig 5.
Coronal femoral nerve angle. Thick-slab 20-mm sagittal MIP image from a 3D SHINKEI acquisition (A) obtained at a coronal angle of 31° (B) optimally demonstrates the right femoral nerve (arrows, A) from its origin to the maximum length. Deg indicates degree.
- Fig 6.
Femoral and sciatic nerve calibers. Thick-slab 20-mm sagittal MIP images from a 3D SHINKEI acquisition through the abdomen (A) and pelvis (B) show the femoral nerve diameter (4.8 mm), which is almost one-half of sciatic nerve diameter (9.7 mm).
