MRI Brain Perfusion Scan

Specimen Required

NONE

Fasting Required

Purpose of the Test

This test is used to evaluate blood flow in the brain and to detect areas of decreased blood flow, which can be a sign of stroke, tumor, or other brain abnormalities.

When this test is required

This test may be ordered if a patient has symptoms such as headache, dizziness, confusion, or numbness that may be related to decreased blood flow in the brain. It may also be ordered as part of a diagnostic workup for stroke or other brain abnormalities.

What the Test Detects

This test is used to evaluate blood flow in the brain using MRI technology. The MRI machine creates images of the brain while a contrast material is injected into a vein in the arm. The contrast material helps to highlight areas of decreased blood flow in the brain.

Preparation for the Test

No specific preparation is needed for an MRI brain perfusion scan. However, patients should inform their doctor if they have any metal implants or devices in their body that may interfere with the MRI.

Sample Requirements

No sample is required for this test.

Additional Notes

The contrast material used in this test may cause temporary side effects such as flushing, headache, or a metallic taste in the mouth. In rare cases, it may cause an allergic reaction. Patients should inform their doctor if they have any allergies or medical conditions that may affect the test. The MRI machine may also cause discomfort for patients who are claustrophobic or anxious.
