MRI Brachial Plexus With Contrast

Specimen Required

NONE

Fasting Required

Purpose of the Test

An MRI Brachial Plexus with Contrast is a diagnostic test used to examine the brachial plexus, which is a network of nerves that control the movement and sensation of the arm. The test is ordered to detect any abnormalities, such as tumors or injuries, that may be affecting the brachial plexus.

When this test is required

This test is typically ordered by a healthcare provider when a patient has symptoms suggestive of a brachial plexus injury or abnormality. It may also be ordered to monitor the progression of a known condition affecting the brachial plexus.

What the Test Detects

During an MRI Brachial Plexus with Contrast, a contrast dye is injected into the patient’s arm, which helps to highlight the nerves and blood vessels in the brachial plexus. The patient then lies on a table that slides into a large, cylindrical machine that uses magnetic fields and radio waves to produce detailed images of the brachial plexus.

Preparation for the Test

Before the test, the patient will be instructed to remove any metal objects, such as jewelry or eyeglasses, and to wear comfortable clothing without any metal fastenings. The patient may also be instructed to avoid eating or drinking for a few hours before the test, depending on the specific instructions of the healthcare provider.

Sample Requirements

No sample is required for this test.

Additional Notes

The contrast dye used during an MRI Brachial Plexus with Contrast is generally safe, but there is a small risk of an allergic reaction. Patients with kidney problems may also be at risk for complications from the contrast dye, so it is important to inform the healthcare provider if you have any kidney problems. Additionally, because an MRI uses strong magnetic fields, patients with certain types of metal implants or devices, such as pacemakers or cochlear implants, may not be able to undergo the test.
