FIG 2. When the flow signal intensity in the inferior petrosal sinus was saturated proximally, the flow signal intensity in the left inferior petrosal sinus was saturated whereas the flow signal intensity in the right inferior petrosal sinus was not.
A, Section (lines) and saturation band (rectangle) position.
B, Axial view fluid-attenuated fast low angle shot 2D image. Right transverse sinus and right jugular bulb (arrowheads) and right inferior petrosal sinus (arrow) show bright signal intensity. No vascular signal intensity can be seen in the left inferior petrosal sinus and internal carotid arteries.
