Background
For the study of these structures we have high resolution images from a 16 channel multidetector CT scanner in axial,
sagittal and coronal planes.
0,6 millimeters slices of routine CT head scans,
and an advantage workstation GE 4.4 for post-processing are used to study normal CT anatomy of these foramina.
We view the slices using a high resolution reconstruction algorithm and bone windowing.
We study ten structures: anterior and posterior ethmoidal canals,
foramen venosum,
craniopharyngeal canal,
canalis basilaris medianus,
petromastoidal canal,
posterior condylar canal,
palatovaginal canal and inferior tympanic and mastoid canaliculi.
We also review the anatomy of these foramina,
their neurovascular contents,
and their spatial relationships between the head and intracranial contents.
