We investigated the flow patterns in the jugular veins of two subject groups, one normal and one with suspected anamolies, using MRI-based CFD. Our results show that there are two types of venous geometries and flow patterns: (1) One which has helical flow in the jugular bulb (the junction between the sigmoid sinus and jugular vein), which results in a relatively straight flow in the jugular vein; (2) and another in which the jugular bulb is shaped such that it redirects flow at a right angle to the jugular vein, which creates pronounced helical flow pattern.
