Name of the Procedure:

Cerebrospinal fluid flow imaging, cisternography

Summary

Cisternography is a specialized imaging technique used to visualize the flow of cerebrospinal fluid (CSF) within the brain and spinal cord. This procedure does not involve introducing any additional materials into the body.

Purpose

Cisternography helps diagnose conditions related to abnormal CSF flow such as hydrocephalus, CSF leaks, or blockages. The goal is to pinpoint the exact location and cause of CSF flow disturbances to aid in appropriate treatment planning.

Indications

• Persistent headaches
• Suspected CSF leaks, often indicated by clear nasal discharge
• Hydrocephalus (build-up of CSF in the brain)
• Post-surgical follow-up for brain or spinal surgeries
• Congenital abnormalities in CSF pathways

Preparation

• The patient may be advised to fast for a few hours before the procedure.
• Medication adjustments may be necessary, especially for those on blood thinners.
• Pre-procedure imaging tests such as MRI or CT scans may be required for detailed anatomical information.

Procedure Description

1. The patient is positioned on the imaging table.
2. A special camera or series of cameras are used to capture images of CSF flow.
3. The patient may need to change positions during the procedure to help facilitate the imaging process.
4. No contrast material or other substances are introduced into the body for this type of imaging.

Duration

The procedure typically takes between 1 to 2 hours.

Setting

Cisternography is usually performed in a hospital's radiology department or an outpatient imaging center.

Personnel

• Radiologist: A doctor specialized in interpreting medical images who performs and analyzes the results.
• Radiology technician: Assists with the imaging equipment and positioning the patient.
• Nurse: May provide initial patient preparation and assist during the procedure.

Risks and Complications

• Minor discomfort from remaining still for a prolonged period.
• Extremely rare instances of allergic reactions to materials used, although none are typically introduced in this procedure.
• Rare technical issues with imaging equipment.

Benefits

• Provides valuable diagnostic information on CSF flow.
• Can help determine the need for and type of further treatment.
• Non-invasive and does not require the introduction of any foreign material.

Recovery

• Patients can usually resume normal activities immediately after the procedure.
• Follow-up appointments with a neurologist or neurosurgeon may be necessary based on the findings.

Alternatives

• MRI or CT scans with contrast may provide alternative ways to visualize CSF flow.
• Intrathecal contrast-enhanced MRI involves introducing a contrast material into the spinal canal.

Patient Experience

• Patients might feel some discomfort from lying still for the imaging process.
• Generally, there is no pain associated with cisternography.
• Relaxation techniques or listening to music may be offered to enhance patient comfort during the procedure.
