About The Test
What Is MRI Brain + Venogram?
MRI Brain + Venogram is a single, non-invasive scan that combines two advanced imaging sequences:
- MRI Brain: high-resolution pictures of brain tissue.
- MR Venography (Venogram): 3-D mapping of veins and sinuses that drain blood from the brain.
The scan detects problems in both tissue and blood vessels in one appointment—no radiation, no surgery.
List of Parameters
- Brain parenchyma (gray & white matter)
- Cerebral venous sinuses (superior sagittal, transverse, sigmoid)
- Cortical & deep veins
- Vascular flow patterns & possible obstructions
Why This Test
- Rule out venous thrombosis
- Detect stroke, bleeding, tumors
- Evaluate congenital malformations or post-surgical changes
When to Take Test
Benefits
Benefits of Taking the Test
- Zero radiation—safe for children & pregnant women (after 1st trimester)
- Single 30-45 minute session
- 3-D images help neurologists plan precise treatment
Illnesses Diagnosed with MRI Brain + Venogram
- Cerebral venous sinus thrombosis (CVST)
- Ischemic & hemorrhagic stroke
- Brain tumors & cysts
- Arteriovenous malformations (AVMs)
Preparing for test
| Step | What to Do |
|---|---|
| Fasting | 4–6 hours if contrast is planned |
| Clothing | Wear metal-free attire; lockers provided |
| Reports | Bring recent kidney function test |
| Screening | Fill metal-screening form |
| Best slot | Morning appointments help with fasting |
Procedure at Cadabams Diagnostics
- Check-in & screening (10 min)
- IV line if contrast is needed
- Lie on table—head coil gently placed
- Scan—stay still for 20–30 min; earphones for music
- Observation—15 min post-contrast monitoring
Caution Before the Test
- Inform staff about pregnancy, breast-feeding, or metallic implants
- Remove all jewelry & credit cards
Test Results
Results and Interpretations
| Finding / Observation | Description (Example) | General Interpretation / Significance (Example) |
|---|---|---|
| Normal | Patent veins, clear brain tissue | No clots or lesions |
| Hypointense filling defect | Sinus blocked by clot | Possible CVST |
| Hyperintense lesion | Bright spot on scan | Tumor or hemorrhage—further tests advised |
| Vascular Malformation | A cluster of small medullary veins converging into a central vein, often forming a “caput medusae” pattern on post-contrast MRI sequences. | A common and typically benign congenital variant. DVAs are usually asymptomatic and require no treatment, but may coexist with cavernous malformations in rare cases. |
| Stenosis / Narrowing | The sigmoid sinus (or another major venous sinus) appears constricted or narrowed in diameter on MRI/MRV imaging. | May suggest intracranial venous hypertension, especially in patients with pseudotumor cerebri (IIH). Clinical correlation with symptoms and pressure measurements is needed. |
| Incidental Finding | A small, rounded, fluid-filled cyst in the region of the pineal gland, typically less than 10 mm in diameter. | A benign and common incidental finding. Rarely causes symptoms unless very large or compressing adjacent structures. Usually requires no follow-up or simple monitoring. |
Risks & Limitations
- Gadolinium contrast: tiny chance of allergy; kidney function test required.
- Metal implants: pacemakers, cochlear implants, or certain clips may be unsafe.
- Claustrophobia: open-bore 3T scanners and mild sedation are available at Cadabams Diagnostics.
FAQs
How long does the scan take?
30–45 minutes total.
Is contrast always necessary?
No. Your doctor decides based on symptoms.
Can children undergo this scan?
Yes—3T scanners are child-friendly and radiation-free.
When will I get the report?
Same evening via email or printed copy.
Do I need follow-up imaging?
Only if an abnormality is found; neurologist will guide.
What is the difference between an MRI Brain and an MRI Brain with Venogram?
A standard MRI Brain focuses on providing detailed images of the brain's structure and tissues (e.g., white matter, gray matter, ventricles) to look for abnormalities like tumors, strokes, inflammation, or degenerative diseases.
An MRI Brain with Venogram includes all the components of a standard brain MRI but adds specific imaging sequences (the "Venogram" part) designed to visualize the brain's veins and how blood is flowing through them. This is crucial for detecting conditions like blood clots in the veins (cerebral venous thrombosis), narrowing of veins (venous stenosis), or venous malformations. So, it's a more specialized scan when venous issues are suspected.
How much does an MRI Brain with Venogram cost?
The cost of an MRI Brain with Venogram can vary depending on several factors, including geographic location, the specifics of the procedure (e.g., with or without contrast), and your insurance coverage.
