MRI Reporting only (BDWI) (Per Study)

Specimen Required

NONE

Fasting Required

Purpose of the Test

The test is useful in diagnosing and evaluating a range of medical conditions affecting the brain, such as strokes, tumors, infections, and degenerative disorders. It can help identify the location and severity of abnormalities, track their progression over time, and monitor the effectiveness of treatment.

When this test is required

The DWI test is typically ordered by a physician when a patient is experiencing symptoms that may be related to a brain disorder or as a follow-up to other imaging tests that were inconclusive. It may also be ordered periodically to monitor the progression of a chronic condition or in cases where a new medical concern arises.

What the Test Detects

The DWI test uses MRI technology to produce detailed images of the brain’s structure and function. It is based on the principle of diffusion, which measures the random movement of water molecules in the brain’s tissues. This test can help detect changes in the brain’s tissues, such as swelling, inflammation, and damage, that may not be visible on other imaging tests.

Preparation for the Test

The patient should inform their doctor of any allergies or medical conditions they may have, especially if they have a history of kidney disease or problems with gadolinium-based contrast agents. The patient will also need to remove any metal objects before the test, as they can interfere with the MRI machine. In some cases, the patient may need to fast for a few hours prior to the test.

Sample Requirements

No sample is required for an MRI Reporting only (BDWI) test.

Additional Notes

The test is generally considered safe, but there are some risks associated with MRI technology, such as the rare possibility of an allergic reaction to the contrast agent or complications from having metal objects in the body. Patients should inform their doctor of any allergies or medical conditions they may have before the test.
