What does a submentovertex view in radiology show?

A submentovertex view in radiology is specifically designed to visualize the base of the skull. This projection involves positioning the patient so that the X-ray beam is directed upwards from below the chin (submentum) toward the vertex of the skull. The resulting images provide critical details about the anatomical structures at the base of the skull, including the occipital bone and the foramen magnum, which are important when assessing trauma, tumors, or other pathological conditions in that area.

While the other choices pertain to various regions of the skull and surrounding structures, they do not accurately reflect the primary focus of the submentovertex view. Thus, the option pertaining to the base of the skull aligns perfectly with the intended diagnostic purpose of this specific radiographic technique.
