MRI Brain with Angiography Without Contrast Overview

  • Scan time: 20–30 minutes
  • Radiation: None
  • Contrast dye: Zero
  • Same-day reporting: Available

List of Parameters

List of Parameters Considered During the MRI Brain with Angiography

ParameterWhat We MeasureWhy It Matters
Arterial circle morphologyShape & symmetry of Circle of WillisPredicts collateral flow in stroke
Stenosis grading% narrowing of arteriesGuides surgical or medical therapy
Aneurysm diameter & neck widthSize and base of bulging vesselDetermines rupture risk and treatment options

When to Take Test

When to Take 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.

Benefits

Benefits of taking the Test

  • No gadolinium contrast—kidney-safe
  • High-resolution 3D imaging
  • Zero radiation exposure
  • Quick outpatient procedure
  • 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

Preparing for MRI Brain with Angiography

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

  1. Check-in: 15 minutes for paperwork and screening.
  2. Positioning: Lie supine; head placed in a cushioned coil.
  3. Earplugs & headset: Reduce scanner noise; music on request.
  4. Scan: 20–30 minutes; remain still.
  5. Alert system: Squeeze ball to pause if uncomfortable.
  6. Completion: Immediate dressing; images sent to PACS.

Risks and Limitations of MRI Brain with Angiography

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.

Test Results

Results and Interpretations

Condition/FindingsDescriptionGeneral Interpretation / Significance
NormalPatent vessels, no stenosisRoutine follow-up as advised
50 % stenosisReduced lumen at M1 segmentRisk factor control, possible intervention
3 mm aneurysmSaccular outpouching at anterior communicating arteryLow rupture risk—annual surveillance
AVM nidusTangle of vessels with early venous drainageReferral to neuro-interventional team
Vessel DissectionDissection 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 AbnormalityIntracranial 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 FindingsSmall 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.

FAQs
