A CSF flow study is performed using MRI techniques to assess and quantify the flow of CSF.
What is a CSF flow study?
The most common technique used for a CSF flow study is the 2D phase contrast MRI using flow-sensitive coding.
- A CSF flow study is done to check the patency of the third ventricle, normal pressure hydrocephalus, and aqueduct stenosis.
- It is also useful in determining the CSF flow at the cervicomedullary junction.
- The flow study gives a lot of information about the Chiari I malformation as well.
A CSF Flow study is very useful to understand what happens inside the brain and cranium without surgery.
How is the CSF flow study performed?
A CSF Flow study will need the use of an anesthetic:
- A lumbar puncture is done to inject a radioactive fluid around your spinal cord in the lower back region.
- The MRI scan is then performed.
The CSF flow study takes a little longer than a regular MRI scan.
Side effects/risks of CSF flow study
A CSF flow study has a few minor side effects and some rare risks:
- Headache that might need some medicines and rest .
- Low blood pressure and dizziness.
- Some bleeding from the site of injection.
- Temporary nerve damage.
- Allergy to the dye.
Preparation before performing CSF flow study
The staff or technician will prepare you for the CSF flow study:
- The procedure will be explained.
- If you take a blood thinner, your doctor may ask you to stop it for the test.
- You will be advised to bring all your medication along on the day of the test.
- Avoid alcohol or other recreational drugs before the test.
Post-care after CSF flow study
There are a few post care instruction you will be advised after the CSF Flow study has been completed:
- Lie flat on your back to reduce headache.
- Your vitals will be monitored before you are released.
- Wake up and stand up slowly to avoid dizziness.
