Headaches that won’t go away. Blurred vision. Unexplained dizziness. These symptoms are easy to dismiss, but sometimes, they may signal something deeper that needs medical attention. At the Dr. Rami Hamed Center (DRHC) in Dubai, we understand how worrisome neurological symptoms can be, and we offer advanced diagnostic tools like the MRV (Magnetic Resonance Venography) brain scan to get the answers you need.
In this blog, we’ll explain what an MRV brain scan is, the symptoms that should never be ignored, and how early detection can guide life-saving care.
What Is an MRV Brain Scan?
An MRV (Magnetic Resonance Venography) scan is a type of MRI that focuses on the veins in your brain. While a regular MRI shows brain structures and tissues, an MRV specifically looks at blood flow through the brain’s venous system. This is particularly useful in detecting:
- Cerebral venous sinus thrombosis (CVST) – a blood clot in the brain’s veins
- Venous malformations – abnormal connections or development of veins
- Compression or narrowing of veins
- Intracranial hypertension (elevated brain pressure)
- Other conditions that can affect venous drainage and cause serious neurological symptoms
At DRHC Dubai, MRV scans are conducted using advanced, high-resolution MRI technology to provide accurate and detailed imaging without the need for invasive procedures.
Symptoms That Shouldn’t Be Ignored
If you’re experiencing any of the following symptoms—especially if they are new, persistent, or worsening—it’s important to seek medical evaluation:
- Persistent or severe headaches (especially different from your usual headaches)
- Blurred or double vision
- Unexplained dizziness or balance problems
- Seizures with no known cause
- Swelling of the optic nerves (papilledema)
- Nausea or vomiting not linked to other illnesses
- Unusual fatigue, confusion, or memory problems
While many of these symptoms can have benign causes, they can also be signs of reduced or blocked blood flow in the brain's veins. The MRV scan helps pinpoint the cause so you can receive the right care.
Is the MRV Scan Safe and Pain-Free?
Yes. An MRV scan is:
- Non-invasive – no surgery or needles are involved
- Painless – you simply lie still while the machine does the work
- Radiation-free – it uses magnetic fields and radio waves, not X-rays
- Safe for most patients, including children and older adults
Depending on your condition, contrast dye may or may not be used. If contrast is needed, our team ensures it’s administered safely, especially if you have allergies or kidney concerns.
What Happens During the Scan?
The MRV scan usually takes about 30 to 45 minutes. Here’s what you can expect at DRHC Dubai:
- Preparation: You’ll be asked to remove any metal objects and lie comfortably on the MRI table.
- Imaging: The table slides into the scanner. You’ll hear some humming or tapping sounds, which are normal.
- Aftercare: There’s no downtime—you can resume your usual activities right away. If contrast was used, we recommend drinking fluids to help flush it from your system.
What Will the Results Tell Me?
The MRV scan gives detailed images of the veins in your brain, helping doctors detect:
- Blockages or blood clots
- Narrowing or abnormalities in venous structure
- Signs of elevated intracranial pressure
- Clues related to unexplained headaches, vision problems, or seizures
Once your scan is complete, our neurologists at DRHC Dubai will carefully review the results and discuss them with you in clear, compassionate language. If treatment is needed, we’ll create a personalized plan tailored to your condition and concerns.

Frequently Asked Questions (FAQs)
Q1: Is MRV better than a regular MRI for detecting brain clots?
A: An MRV scan is specifically designed to visualize veins, so it's often more effective than a regular MRI when looking for conditions like cerebral venous sinus thrombosis (CVST).
Q2: Will I need contrast dye for an MRV?
A: In many cases, MRV scans can be done without contrast. If contrast is needed, we’ll discuss the risks and ensure you are safely screened beforehand.
Q3: Is an MRV scan safe during pregnancy?
A: Generally, MRI (including MRV) is considered safe during pregnancy, especially without contrast. We evaluate each case individually to ensure the safety of both mother and baby.
Q4: How soon will I get my results?
A: Most patients receive results within 24 to 48 hours. A follow-up appointment will be scheduled to explain the findings and recommend next steps.
Q5: Can children have an MRV scan?
A: Yes. MRV scans are safe for children. If your child is nervous or unable to stay still for long, we may recommend sedation, administered under expert care.
