Calculating cerebrospinal fluid flow through the cerebral aqueduct of the rat. Radio-opaque contrast (20 μl) was simultaneously injected into each lateral ventricle at 2 μl/min for 10 min while plain CT images (0.6 mm slice thickness) were taken over 60 minutes. A small region-of-interest (ROI) (yellow box, arrow) was positioned within the centre of the aqueduct and the decay rate used to generate flow maps. An additional movie file shows this in more detail [see Additional file 1].
