Figures
- Fig 1.
Initial scout image shows the nerve root in the neural foramen, indicating an appropriate injection level. The distance tool is used to calculate an appropriate skin injection site. Once the technologists become familiar with the anatomy, many studies can be done with only one or two scout images.
- Fig 2.
Image from CT fluoroscopy-guided nerve root block demonstrates the needle tip in the outer neural foramen. Note that the image is not as sharp as standard CT images due to the low mA used with this technique.
- Fig 3.
S1 nerve root block shows the needle traversing the sacral foramen and lying directly adjacent to the S1 nerve.
