CT Anatomy Neck Vasculature (Axial) - Video Lesson

Hey everybody, welcome back. This lesson is about the vasculature of the neck as seen in CT imaging in the axial plane. But first, we'll start with a maximum intensity projection. A maximum intensity projection, or MIP, is helpful because it can be used to create the appearance of a three d image. The arterial structures of the head and neck start directly or indirectly from the aortic arch. There are three vessels that branch directly from the aortic arch. Blood flows through the arch from right to left, so we typically name them from right to left. The first branch is the brachiocephalic artery. The name tells us what this vessel supplies. Brachio means arm. Cephalic means head. The brachiocephalic artery immediately branches into the right subclavian artery to supply the right arm and the right common carotid artery to supply the right side of the head. The next branch of the aortic arch is the left common carotid artery. It's exactly like the right common
