Ct Cisternogram (Overview)

Ct cisternography is a procedure used to identify subtle leaks of spinal fluid along the skull base. Images are obtained in various orientations and often with the patient in various positions before and after a liquid which shows up with ct (contrast) is instilled into the spinal fluid. Since ct images show bone detail well the test works well to identify leaks in the skull base region.
