Stenvers projection
Stenvers Projection
Stenvers projection (pronunciation: sten-vərs prə-ˈjek-shən) is a radiographic view used in the field of radiology to visualize the petrous part of the temporal bone and the mastoid process. It is named after Dutch radiologist, Gerrit Stenvers.
Etymology
The term "Stenvers projection" is derived from the name of the Dutch radiologist, Gerrit Stenvers, who first described this specific radiographic view. The word "projection" in this context is used to describe the path that the x-ray beam takes through the patient's body from the source to the image receptor.
Procedure
The Stenvers projection is performed with the patient's head tilted 45 degrees towards the affected side and the central ray angled 20 degrees caudad. This positioning allows for a clear view of the petrous part of the temporal bone and the mastoid process.
