Head and neck bones and vessels on CT

TotalSegmentator outlines bones, cartilage, and major vessels on a head and neck CT scan: the hyoid, zygomatic arches, styloid processes, thyroid and cricoid cartilages, air in the larynx, internal carotid arteries, and internal jugular veins. Research uses include reference values for anatomy, carotid size and length, and how these structures lie relative to each other. On PET or SPECT, uptake can be read along the carotid arteries, with the jugular veins as a blood-pool reference region.

Find answers to research questions like: How does carotid artery size vary with sex and body height? How do hyoid size and position change with age? How does carotid artery uptake compare with uptake in the jugular veins?
