Study Notes
Jugular Foramina Projections
- The angle for the submento-vertical projection of the jugular foramina is 20° caudal.
- The jugular foramina are located between the petrous temporal and occipital bones.
- To image the jugular foramina, the X-ray beam should be directed at an angle of 70° to the orbito-meatal plane.
- The X-ray beam should be centered at the level of the external auditory meatus for imaging the jugular foramina.
- Imaging of jugular foramina is typically done on both sides simultaneously on a single image.
- Traditional difficulty associated with the projections of the temporal bones is mentioned in the context of jugular foramina imaging.
