Purpose of the Test

The MRI Trigeminal without contrast is a non-invasive and painless way to examine the trigeminal nerve in detail. It can help diagnose the cause of facial pain, numbness, tingling, or other unusual sensations in the face. It can also be used to rule out other conditions that can cause similar symptoms.

When this test is required

The MRI Trigeminal without contrast is typically requested by a doctor if you are experiencing symptoms of trigeminal neuralgia or other conditions that affect the trigeminal nerve. Your doctor may also order this test if you have been diagnosed with multiple sclerosis, as this condition can cause demyelination (damage to the protective covering of nerve fibers) of the trigeminal nerve.

What the Test Detects

The MRI Trigeminal without contrast is used to examine the trigeminal nerve in the face and diagnose conditions that affect it.

Preparation for the Test

There is usually no special preparation needed for an MRI Trigeminal without contrast. However, you should inform your doctor if you have any metal in your body, such as a pacemaker, as this may affect your ability to undergo the test. You may also be asked to remove any jewelry, eyeglasses, or other metal objects before the test. It is important to follow any instructions provided by your doctor or the imaging center to ensure the best possible results.

Sample Requirements

No sample is required for an MRI Trigeminal without contrast. The test is non-invasive and does not involve any needles or other medical instruments.

Additional Notes

It is important to inform your doctor if you have any metal in your body, such as a pacemaker or metal implants, as this may affect your ability to undergo the test. Additionally, you should tell your doctor if you are pregnant, as MRI is generally not recommended during pregnancy unless it is absolutely necessary. While the MRI Trigeminal without contrast is generally safe and non-invasive, some people may experience claustrophobia (fear of enclosed spaces) during the test. If you are prone to claustrophobia, you may be given a mild sedative to help you relax during the procedure.
