MRI Diffusion and Perfusion with Contrast (DRVS)
Scan Cost

Magnetic Resonance Imaging (MRI) Diffusion and Perfusion with Contrast, also known as Dynamic Susceptibility Contrast MRI (DSC-MRI) or simply DRVS, is a type of imaging technique that employs magnetic fields and radio waves to create detailed pictures of the body's internal structures. This unique technique is particularly beneficial in assessing the physiological characteristics of tissues, such as blood flow and volume, cellular density, and the permeability of blood vessels.

Diffusion MRI focuses on the movement of water molecules in the tissues, providing information about their cellular density and integrity. Perfusion MRI, on the other hand, measures the flow of blood through the tissues, giving valuable data about their functionality and vitality. The addition of contrast dye further enhances the visibility of these structures, making it easier for doctors to identify abnormalities.This combination of techniques is especially useful in diagnosing and managing conditions such as tumors, strokes, and other neurological disorders, where understanding the tissue's functionality is as important as knowing its structure.

Specific Instructions:

Here are some guidelines to prepare for an MRI Diffusion & Perfusion with Contrast (DRVS) test:

• Medical History: Inform your doctor about your complete medical history, including any allergies, prior surgeries, or conditions like kidney disease. This is essential as the contrast agent used in the procedure might not be suitable for everyone.

• Metallic Implants: The presence of metallic implants in your body such as pacemakers, artificial joints, or metallic clips from a previous surgery can interfere with the MRI. Make sure to inform your doctor about these.

• Pregnancy: If you are pregnant, suspect that you might be, or are breastfeeding, notify your doctor. While MRI is generally considered safe, the use of contrast agents may not be recommended during pregnancy or breastfeeding.

• Preparation: Wear comfortable, loose-fitting clothes without any metallic components like zippers or buttons. You may be asked to remove items such as jewelry, glasses, and hairpins before the test.

• Fasting: Usually, fasting is not necessary before an MRI scan. However, specific instructions may vary depending on your doctor's preferences and the specific protocols of the imaging center.

What is an MRI Diffusion & Perfusion with Contrast (DRVS)?

An MRI Diffusion & Perfusion with Contrast (DRVS) is an imaging test that uses magnetic fields and radio waves to create detailed images of the body's internal structures. It is especially useful for assessing physiological characteristics of tissues such as blood flow, cellular density, and blood vessel permeability.

How is the procedure performed?

During the procedure, you will lie on a flat table that slides into the MRI machine. The machine will make loud noises as it captures images, and you will be asked to remain still. If contrast is used, it will be injected into a vein in your arm partway through the test.

What are the risks of this procedure?

MRIs are generally safe and non-invasive. However, the contrast agent used may cause allergic reactions or kidney problems in rare cases. Make sure to discuss any concerns with your doctor prior to the procedure.

How long does the procedure take?

The procedure typically lasts between 30 minutes to an hour, depending on the specific areas being imaged.

Do I need to prepare for the test?

You should wear comfortable clothes free of metal, and you may need to remove any jewelry or other metallic items. In some cases, you may be asked to fast for a few hours before the test, but your doctor will give you specific instructions.

What can this test detect?

This test is particularly useful in diagnosing and managing conditions like tumors, strokes, and other neurological disorders.

Can I take my medications before the test?

Yes, you can continue to take your regular medications unless your doctor instructs otherwise.

Is the procedure painful?

The procedure itself is not painful. However, some people may feel uncomfortable or claustrophobic inside the MRI machine.

What if I have metal implants in my body?

The presence of metal implants can interfere with the MRI scan. Make sure to inform your doctor about any implants or devices in your body.

Can pregnant women undergo this procedure?

While MRI is generally considered safe during pregnancy, the use of contrast agents may not be recommended. Always inform your doctor if you're pregnant, suspect you might be, or are breastfeeding.

MRI Diffusion & Perfusion with Contrast (DRVS) is a powerful diagnostic tool that goes beyond the structure of tissues and delves into their functionality. This makes it invaluable in diagnosing and managing various health conditions, particularly those involving the brain. Always discuss any concerns or questions you may have with your doctor to ensure you have a clear understanding of the procedure.
