I would like to know how much intrathecal contrast to inject for a CT cisternogram via a lumbar puncture approach. I am not sure.
Lumbar puncture, thanks.
Is That a lumbar pucture or a C1-C2 puncture???.
We generally use 3-6 ml of the lowest concentration available, generally 180 mg. You can use a higher concentration, 220-240 mg, but will need to use less volume.
