About The Test
- Scan time: 20–30 minutes
- Radiation: None
- Contrast dye: Zero
- Same-day reporting: Available
List of Parameters
| Parameter | What We Measure | Why It Matters |
|---|---|---|
| Arterial circle morphology | Shape & symmetry of Circle of Willis | Predicts collateral flow in stroke |
| Stenosis grading | % narrowing of arteries | Guides surgical or medical therapy |
| Aneurysm diameter & neck width | Size and base of bulging vessel | Determines rupture risk and treatment options |
Why This Test
- Stroke detection: Identify large-vessel occlusion early.
- Aneurysm screening: Family history or polycystic kidney disease.
- Headache or vertigo evaluation: Rule out vascular causes.
- Pre-operative mapping: Before neurosurgery or cochlear implantation.
When to Take Test
Benefits
Benefits of taking the Test

- Reimbursed by most insurance plans
Illnesses Diagnosed by MRI Brain with Angiography
- Ischemic & haemorrhagic stroke
- Cerebral aneurysms
- Arteriovenous malformations (AVMs)
- Moyamoya disease
- Vertebro-basilar insufficiency
Preparing for test
Instructions
- Fasting: Not required, but avoid heavy meals 2 hrs prior.
- Metal objects: Remove jewellery, hairpins, hearing aids.
- Clothing: Opt for cotton outfits; lockers provided.
Prerequisites
- Medical history form
- Serum creatinine only if kidney disease suspected
Best Time to Take
Morning appointments (7 a.m.–11 a.m.) mean shorter wait times and fresher technologists.
Eligibility
- Adults: All ages
- Children (>5 yrs): Usually without sedation
- Toddlers: Paediatric sedation consultation required
Procedure for Taking MRI Brain with Angiography Without Contrast
- Check-in: 15 minutes for paperwork and screening.
- Positioning: Lie supine; head placed in a cushioned coil.
- Earplugs & headset: Reduce scanner noise; music on request.
- Scan: 20–30 minutes; remain still.
- Alert system: Squeeze ball to pause if uncomfortable.
- Completion: Immediate dressing; images sent to PACS.
Test Results
Results and Interpretations
| Condition/Findings | Description | General Interpretation / Significance |
|---|---|---|
| Normal | Patent vessels, no stenosis | Routine follow-up as advised |
| 50 % stenosis | Reduced lumen at M1 segment | Risk factor control, possible intervention |
| 3 mm aneurysm | Saccular outpouching at anterior communicating artery | Low rupture risk—annual surveillance |
| AVM nidus | Tangle of vessels with early venous drainage | Referral to neuro-interventional team |
| Vessel Dissection | Dissection flap noted in the V4 segment of the left vertebral artery. | A tear in the vessel wall may lead to luminal narrowing, thrombus formation, or stroke. Urgent assessment and vascular neurology referral typically indicated. |
| No Significant Vascular Abnormality | Intracranial arteries are patent throughout. No aneurysm, stenosis, or vascular malformation identified. | A reassuring finding indicating that major intracranial vessels are within normal limits. Confirms absence of clinically significant abnormalities based on the technique’s resolution and scope. |
| Incidental Findings | Small pineal gland cyst; likely benign. | Findings unrelated to the vascular system but often noted for completeness. Most are benign and don’t require intervention unless symptomatic or atypical in appearance. |
Risks & Limitations
MRI Safety Considerations
- Pacemakers: Most modern MRI-conditional devices are allowed; older models may not be.
- Implants: Cochlear implants, certain aneurysm clips—declare them beforehand.
- Claustrophobia: Open-bore systems and mild sedation options available.
Limitations in Very Small Vessel Visualisation
Vessels below 1 mm may appear faint; tiny aneurysms or distal stenoses can be missed. Contrast MRA or digital subtraction angiography may be advised if clinical suspicion remains high.
FAQs
Is the scan painful?
No. You only feel the table moving and hear rhythmic knocking.
How soon can I resume normal activities?
Immediately—no recovery time needed.
Can I undergo MRI if I have dental implants?
Most titanium implants are safe; inform the technologist for verification.
Will I need a follow-up contrast study?
Only if the non-contrast images are inconclusive or a tiny abnormality is suspected.
Why is an MRI scan of brain blood vessels without contrast dye important?
The without contrast aspect is important because it means the images of your brain blood vessels are obtained without injecting any special dye (contrast medium). This makes the MRI scan brain blood vessels without dye an excellent option for patients who may have allergies to contrast media, have impaired kidney function, or simply wish to avoid any unnecessary substances. It provides valuable diagnostic information with an enhanced safety profile.
What is the approximate cost of an MRI Brain Angiography with no contrast?
The MRI brain angiography no contrast cost can vary based on several factors, including geographic location and the specifics of the imaging center.
