Is an MRA/MRV scan painful?

No injections feel like a routine blood test; the scan is painless.

How long does an MRA/MRV scan usually take?

An MRA/MRV scan typically takes between 30 to 90 minutes. The exact duration depends on the specific body part being scanned, the number of imaging sequences required for a comprehensive assessment, and whether contrast is administered.

How soon are results available?

Most patients receive reports the same evening; emergency cases within 30 minutes.

What is the main difference between a regular MRI and an MRA/MRV?

While both regular MRI and MRA/MRV use the same fundamental MRI technology (magnets and radio waves), MRA/MRV uses specialized software and imaging sequences optimized to visualize blood vessels (arteries for MRA, veins for MRV). A regular MRI focuses on imaging general organs, soft tissues, bones, and other structures.

Can I drive after contrast?

Yes, unless you take sedation. In that case, bring a friend to drive home.

How much does an MRA/MRV scan cost at Cadabams Diagnostics?

The cost of an MRI Angiogram/Venogram (MRA/MRV) scan varies. Factors influencing the price include the specific body part imaged, whether a contrast agent is used, and the complexity of the study. For detailed pricing information, contact Cadabams Diagnostics directly.

MRA/MRV (Magnetic resonance angiogram/venogram) Overview

Need a closer look at the blood vessels inside your head or neck? Cadabams Diagnostics offers a fast, painless MRI Angiogram/Venogram (MRA/MRV) — no surgery, no radiation, and results ready within hours. Scan time is only 20–40 minutes, and you can book online in under two minutes.

List of Parameters

List of Parameters Considered During MRA/MRV

Parameter	What We Measure
Vessel lumen diameter	Width of the artery/vein
Flow velocity	Speed of blood movement
Stenosis %	How much vessel is narrowed
Thrombus presence	Blood clots

When to Take Test

Detecting aneurysms – ballooning artery walls before they rupture
Evaluating venous sinus thrombosis – clots in brain veins that mimic migraine
Monitoring vasculitis – inflamed vessels causing daily headaches

Benefits

Benefits of Taking the Test

Zero radiation – safe for children and repeated follow-ups
High-resolution head vessels – see 1 mm abnormalities
Single exam covers MRA MRV head – arteries and veins in one appointment

Illnesses Diagnosed with MRA/MRV

Carotid stenosis
Dural sinus thrombosis
Arteriovenous malformations (AVMs)

Preparing for Test

Preparing for MRA/MRV

Fasting Guidelines

Nothing by mouth 2 h before if contrast is planned

Metal Implant Screening

Fill safety questionnaire; bring implant card

Best Time to Schedule Exam

Morning slots = shorter fast and quicker report

Pre-Requisites

Recent eGFR blood report (if contrast needed)
Previous imaging CDs for comparison
Documented allergy history

Best Time to Take the Test

Morning slots – lower waiting time and full radiologist support
Emergency stroke protocol – 24×7 availability with neurologist on call

Eligibility

Adults and children above 5 years (younger kids need sedation)
Pregnancy: MRA without contrast is safe; consult your doctor
Weight limit: 150 kg (330 lb) table capacity

Procedure for Taking an MRI Angiogram/Venogram

Check-in & IV line – 10 min
Scanning steps – lie still for 20–40 min; expect loud knocking sounds
Post-contrast observation – 15 min to watch for rare reactions

Caution Before Taking the Test

Contrast allergy? Pre-medication provided
Renal function below threshold? We switch to non-contrast sequences
Severe claustrophobia? Oral sedation available—bring an escort

Risks & Limitations of MRA/MRV

Contrast Dye Cautions

Rare allergy (<1 %)
Requires good kidney function (eGFR ≥30)

Magnetic Field Restrictions

Pacemakers, cochlear implants, and certain aneurysm clips may be unsafe

Claustrophobia Solutions

70 cm wide-bore scanner
Mirror glasses, music, or mild sedation on request

Test Results

Results and Interpretations

Finding / Observation	Description	General Interpretation / Significance
Carotid lumen	5–7 mm	<2 mm = severe stenosis
Flow void	Present	Absent = possible clot
Stenosis %	0–49 %	≥70 % may need surgery
Venous sinus	Patent	Filling defect = thrombosis
No evidence of significant vascular malformation	No arteriovenous malformation (AVM), fistula, or abnormal vascular tangle identified.	Rules out major congenital or acquired vascular anomalies in the region; lowers concern for hemorrhagic events or seizures due to vascular causes.
Patent renal arteries bilaterally	Right and left renal arteries appear normal in caliber and enhance well with contrast, without signs of narrowing.	Suggests adequate renal perfusion and makes renovascular hypertension less likely.
Chronic occlusion of the left superficial femoral artery	Complete blockage of the left superficial femoral artery, with visible collateral circulation around the occluded segment.	Indicates established peripheral artery disease; presence of collaterals shows vascular adaptation. Management depends on symptoms and functional impact.
