What are the side effects of a cisternogram?
The most common side effects after a cisternogram are pain where you received your injection and headache. Spinal headaches can occur after a lumbar puncture because CSF fluid may leak out of the injection site. This temporary leak causes the pressure in your brain to drop, which can lead to an intense headache.
What is a cisternogram and how is it performed?
A cisternogram is an examination of the spinal fluid flow that surrounds the spinal cord. The spinal canal extends from the lumbar spine (lower back) into the brain and is filled with spinal fluid. By injecting a small amount of radioactivity into the spinal fluid, the flow of the spinal fluid from the spine into the brain can be evaluated.
What is a cerebrospinal fluid cisternogram?
Cisternogram. This test is used to diagnose a cerebrospinal fluid (CSF) leak. It can be ordered with pledgets (for CSF leaks of the head) or without (for spinal leaks or normal-pressure hydrocephalus). Patients: Please do not eat or drink anything for eight hours before this study.
Why are cisternograms with pledgets so difficult to schedule?
Cisternograms with pledgets can be complex to schedule because it requires coordination between the patient's referring physician, the Interventional Radiology Division and the S. Mark Taper Foundation Imaging Center. Because the patient requires a lumbar puncture to occur six hours before imaging can take place.
How long does a cisternogram take?
The scan takes about 30-60 minutes. You will be scheduled for serial scans starting about 24 hours, 48 hours and possibly 72 hours after your initial scan. If you had pledgets placed, they will be removed at the 24-hour scan.
How is a cisternogram performed?
This is done by inserting a thin needle in your lower back into the subarachnoid space filled with the radiopharmaceutical tracer. The tracer travels with the flow of the CSF. Two to six hours later, you will be scanned. Many pictures are taken during the scan to show how the tracer flows with the CSF.
How accurate is a cisternogram?
Both MR cisternography and high-resolution CT failed to definitively locate the CSF fistula in two patients. High-resolution CT was accurate in 93% of patients, whereas MR cisternography was accurate in 89% of patients. The combination of high-resolution CT and MR cisternography was accurate in 96% of patients.
Is cerebrospinal fluid test painful?
A spinal tap is usually done in a hospital. During the procedure: You will lie on your side or sit on an exam table. A provider will clean your back and inject an anesthetic into your skin, so you won't feel pain during the procedure.
Is a cisternogram safe?
Are there any risks with a cisternogram? Complications after a cisternogram are rare, but potential risks include: Allergic reactions to the radioactive substance or anesthesia. Brainstem herniation (pressure inside the skull moves brain tissue).

Postoperatively, patients are placed on bed rest in the hospital, typically for two to three days, to help facilitate the healing process and closely monitor for leak recurrence. The repair site can take four to six weeks to heal completely.
Does CSF leak make you tired?
Although classic symptoms of CSF leaks are severe headaches that improve when lying down, other signs and symptoms are: head pressure, a feeling of a grabbing sensation in the back of the head, extreme fatigue, nausea and vomiting; neck stiffness or pain, brain fogginess– feeling disconnected, photophobia, phonophobia ...
Do they sedate you for a lumbar puncture?
A small special needle is used to remove some fluid from below the spinal cord. Before the needle is used, the doctor will numb the spot where the needle will go. Most children will be awake for this test, but occasionally the test may be done under sedation.
Why was my lumbar puncture so painful?
There is a chance you may feel a sudden sharp pain in one of your legs if the needle touches a nerve in your spinal column. The doctor or nurse will immediately adjust the position of the needle if this happens. Once enough CSF has been taken, the needle is carefully removed and a plaster is put over the puncture site.
How long are you on bed rest after a lumbar puncture?

What is a CT Cisternogram?
Computed tomography (CT) cisternography is a minimally-invasive imaging technique used to visualize the intracranial CSF cisterns using iodinated contrast medium injected into the subarachnoid space.
Will a CT scan show a CSF leak?
CT myelography. This test is considered the gold standard for diagnosing and locating CSF leaks. It uses a CT scan and a contrast dye to locate CSF leaks anywhere in the skull base. It provides the most precise location of a CSF leak and helps to determine the most appropriate treatment plan.
What is an isotope Cisternogram?
Isotope cisternography, first described in 1963 by DiChiro,9–13 is a means of studying the cerebrospinal fluid circulation.
What is a CSF fistula?
Background: Cerebrospinal fluid (CSF) fistula represents a rare neurosurgical entity that can be defined as a communication between the subarachnoid space and nasal fossa or less commonly the ear cavity. It can be spontaneous without an evident etiology or secondary following a skull base surgery or trauma.
What do I need to know about a cisternogram?
A cisternogram is a test used 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.
What will happen during a cisternogram?
Your healthcare provider will first do a lumbar puncture. Medicine will be given to numb the site of your lumbar puncture. Then your healthcare provider will inject a substance called a radioactive tracer into your subarachnoid space. You will need to lie flat in bed until your healthcare provider says it is okay to get up. A scan will be taken 2 to 6 hours later. Several pictures are taken during your scan to show how the tracer flows with the CSF. Scans may be done again at 24 hours, 48 hours, and even 72 hours after the tracer is given. Each scan takes about 1 hour.
What happens if you have a lumbar puncture?
The site of your lumbar puncture could become red, swollen, painful, or infected. Sometimes a lumbar puncture causes a headache. There may be bleeding into the spinal canal. You may develop meningitis or herniation of brain tissue.
How long does it take to scan a CSF?
Scans may be done again at 24 hours, 48 hours, and even 72 hours after the tracer is given. Each scan takes about 1 hour.
What is a cystogram?
A cystogram is a diagnostic procedure that uses X-rays to examine the urinary bladder and if there are any leakages to it. Still X-ray images or fluoroscopy (similar to an X-ray movie) may be used. A cystogram may indicate how well the bladder empties during urination and whether any urine backs up into the kidneys. Doctors may recommend cystogram to access:
Why do you drink fluids after a contrast procedure?
Patients may need to drink additional fluids for a day or so after the procedure to help eliminate the contrast from the system and to help prevent infection of the bladder.
How is contrast put into the bladder?
The catheter will gently be advanced into the bladder. The contrast will then be put into the bladder via the catheter. As the contrast flows into your bladder, X-ray images will be taken. After the contrast has been introduced, the catheter tubing will be clamped to prevent drainage from the bladder.
Is cystogram painful?
Usually, a cystogram is not a painful procedure; however, a patient may complain of some discomfort during the procedure:

What is cisternography for cranial leaks?
Cisternography for evaluation of cranial leaks is usually CT cisternography which involves an injection of radiographic contrast into the intrathecal space via lumbar puncture. then thin cut CT of head is done.#N#Radioisotope cisternography also involves LP injection but radioisotope is used. The imaging thereafter is done periodically over the course of days, looking at brain and spine.#N#The injection itself is usually rather uneventful.
Does a radionuclide cisternogram cause a reaction?
The radionuclide cisternogram caused no reaction but this test can require many trips back to have images taken. With this test I also had pledgets placed in my nose for 24 hours. The pledgets indicated my leak was on the left side with a slightly positive result.
Definition
A radionuclide cisternogram is a nuclear scan test. It is used to diagnose problems with the flow of spinal fluid.
How the Test is Performed
A spinal tap ( lumbar puncture) is done first. Small amounts of radioactive material, called a radioisotope, are injected into the fluid within the spine. The needle is removed immediately after the injection.
How to Prepare for the Test
Most of the time, you do not need to prepare for this test. Your health care provider may give you a medicine to calm your nerves if you are very anxious. You will sign a consent form before the test.
How the Test will Feel
Numbing medicine will be put on your lower back before the lumbar puncture. However, many people find lumbar puncture somewhat uncomfortable. This is often due to the pressure on the spine when the needle is inserted.
Why the Test is Performed
The test is performed to detect problems with flow of spinal fluid and spinal fluid leaks. In some cases, there may be a concern the cerebrospinal fluid (CSF) fluid is leaking after a trauma to the head or a surgery in the head. This test will be done to diagnose the leak.
Normal Results
A normal value indicates normal circulation of CSF through all parts of the brain and spinal cord.
What Abnormal Results Mean
An abnormal result indicates disorders of CSF circulation. These disorders may include:
