Cervical spine (Fuchs view)

The closed mouth odontoid AP view (Fuchs view)​ is a nonangled AP radiograph of C1 and C2. This view focuses primarily on the odontoid process. The standard Fuchs view should not be used in a trauma setting and the modified Fuchs view may be used instead.

  • patient is supine or erect

  • the back of patient's head is placed against the image detector

  • the patient's chin is angled up 35-40°

  • anteroposterior projection

  • centring point

    • the beam is aimed just underneath the chin

  • collimation

    • superior to the TMJ

    • inferior to include  C2/3

    • lateral to include the skin margin

  • orientation  

    • portrait

  • detector size

    • 24 cm x 30 cm

  • exposure

    • 75-80 kVp

    • 20-25 mAs

  • SID

    • 100 cm

  • grid

    • yes (this can vary departmentally)

The entire odontoid process should be visibly; free from obscuring anatomy

More likely to avoid structures overlapping the odontoid than with the open mouth odontoid view.

This view should not be used in a trauma setting (to avoid manipulating a potentially unstable spine) the modified Fuchs view may be used instead; instead of moving the patient's chin, the beam is angled 35-40° upward and the odontoid is targeted just under the chin (the chin is in a neutral position).
