CT Anatomy Neck Vasculature (Sagittal) - Video Lesson

Hey everybody, welcome back. This lesson is about the vasculature of the neck as seen in CT imaging in the sagittal plane. This is a sagittal reformation of the head and neck. Notice that we are near the lateral border of the right side of the neck. This is an interesting slice position because we can see the entire extent of the internal jugular vein. The internal jugular veins receive most of the venous drainage from the head and neck. They are the largest vascular structures of the neck. For example, this structure, called the transverse sinus, carries venous drainage from the brain and ultimately empties into the internal jugular vein on this side of the brain. Anterior to the internal jugular vein, we can also see the sternocleidomastoid muscle. Finally, this bright structure is the subclavian vein. It's very bright with contrast because the patient is being actively injected with iodinated contrast through a vein in their right arm. That dense contrast
