WHAT YOU NEED TO KNOW:
A cisternogram is a test to look for problems in the way your cerebral spinal fluid (CSF) circulates. CSF is the fluid that flows through the subarachnoid space (space that surrounds your brain and spinal cord). This test is also known as a nuclear medicine scan, CSF flow scan, intrathecal scan, and RHISA scan.
Follow up with your healthcare provider as directed:
Write down your questions so you remember to ask them during your visits.
- Drink plenty of liquids , such as water and juices, to help flush the tracer out of your body. The tracer leaves your body quickly through your urine. Your healthcare provider may tell you to flush the toilet 3 times after going to the bathroom. This makes sure that the small amount of tracer that leaves your body does not stay in the toilet bowl. Liquids may also help relieve headaches that sometimes occur after a lumbar puncture.
- Lie down if you have a headache after your lumbar puncture.
Contact your healthcare provider if:
- You have new signs or symptoms.
- You have questions or concerns about your condition or care.
Seek care immediately or call 911 if:
- You have a severe headache that does not get better after you lie down.
- You have bleeding or discharge at the site of the lumbar puncture.
Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances.
