This is done by inserting a thin needle in your lower back into the subarachnoid space filled with the radiopharmaceutical tracer. The tracer travels with the flow of the CSF. Two to six hours later, you will be scanned. Many pictures are taken during the scan to show how the tracer flows with the CSF.

What is CT Cisternography?
CT-cisternography is considered the gold standard examination for evaluation for CSF fistula. In our hospital, a non-contrast HRCT of the skull base in the axial plane is performed first. CT-cisternography with intrathecal injection of low-osmolar contrast material is performed for equivocal cases.
