How accurate is a cisternogram?
The sensitivity of the study is in the range of 50% to 100% and the specificity approaches 100%..
How does cisternogram work?
Cisternography is a type of nuclear medicine imaging.
That's why providers also call this scan a radionuclide cisternogram.
During this test, you receive an injection of radioactive material in your spine.
Radioactive substances allow certain body parts or functions to show up better on imaging scans..
How is CT cisternography done?
CT-cisternography is considered the gold standard examination for evaluation for CSF fistula.
In our hospital, a non-contrast HRCT of the skull base in the axial plane is performed first.
CT-cisternography with intrathecal injection of low-osmolar contrast material is performed for equivocal cases..
What does a cisternogram diagnose?
The test is performed to detect problems with the 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..
What is a cisternogram used for?
A cisternogram scan is a procedure to test how the cerebrospinal fluid (CSF) flows around your brain and spinal cord.
Your healthcare provider might order this test if they suspect you have a CSF leak or a buildup of CSF.
A cisternogram requires a lumbar puncture and a series of imaging exams..
What is a CT cisternography?
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.Oct 28, 2023.
What is CT cisternography?
The patient usually presents either with rhinorrhea or less frequently otorrhea.
Computed tomography (CT) cisternography is widely used in the diagnostic workup of such patients.
It helps to localize the site of leak and to establish the underlying cause..
What is MRI cisternography?
It is a non-invasive imaging technique that uses a strong magnetic field, radio waves and a computer to create detailed images of the cerebrospinal fluid (CSF).
A contrast agent is injected intravenously for better visualization of the CSF flow..
What is the Mr cisternography procedure?
MR cisternography, a fast spin-echo sequence with fat suppression, used an echo train length of 16, a 16-cm field of view with no phase-wrap option, 3-mm-thick sections, 10 000/200/4 (repetition time [TR]/echo time/excita- tions), and a 512 X 192 matrix.
A total of 16 images were obtained in 8 minutes..
What is the purpose of a CT cisternogram?
A cisternogram scan is a procedure to test how the cerebrospinal fluid (CSF) flows around your brain and spinal cord.
Your healthcare provider might order this test if they suspect you have a CSF leak or a buildup of CSF.
A cisternogram requires a lumbar puncture and a series of imaging exams..
- A Myelogram will highlight conditions affecting the spinal cord and the nerves within the spinal canal and help with the treatment plan.
A Cisternogram is used to demonstrate a potential leak of cerebral spinal fluid (CSF) which circulates normally in the space that surrounds your brain and spinal cord. - CT-cisternography with intrathecal injection of low-osmolar contrast material is performed for equivocal cases.
After intrathecal administration of contrast material, the patient is requested to lay down in prone position with the head in the dependent position. - How do I prepare for a cisternogram? You do not have to do anything to prepare for the scan.
You may eat, drink fluids, and take any medicines that you take regularly. - The sensitivity of the study is in the range of 50% to 100% and the specificity approaches 100%.
