@Michael Liz's reference gives the answer as "iodinated contrast material", which is why I didn't think it fit with my suggestion of intra cisterna magna.

But thank you for clarifying that ICM can be considered to be an intrathecal injection. I am not a medical translator, so that's why I had doubts.

Intrathecal An intrathecal injection is an injection into the cerebrospinal fluid. This can be accomplished by injection into the spinal canal or directly into the subarachnoid space of the brain, including the cisterna magna. There is no problem with Liz's answer.

My link is not about contrast material, it's about a location in the brain where drugs can be administered, the "intra cisterna magna" (ICM). So I don't think it fits with Liz's reference. Salman has posted intra cisterna magna as an answer and is a medical student...

The problem with it is that your source mentions "intrathecal", which is an injection into the spine much further down

@ Suzie This fits in with reference from Liz. I.e. contrast material so they can see what they are doing.

might be helpful? This article mentions ICM in the context of administering drugs into the spinal fluid as "intra cisterna magna", but not sure if this is helpful (this is not a specialist field of mine)
