About The Test
MRI Aortic Angiography is a painless scan that maps the aorta from chest to abdomen in one 20–30 minute session. It spots ballooning, tears, blockages and plaque before symptoms turn critical.
At Cadabams Diagnostics our 3 Tesla magnets and AI-assisted post-processing cut table time and deliver verified reports the same evening, so you and your doctor can act fast.
List of Parameters
- Maximum aortic diameter and length
- Patency of branch vessels (renal, mesenteric, carotid)
- Wall thickness, plaque burden and thrombus
- Presence and extent of dissection flap or aneurysm sac
Why This Test
- Detect aortic aneurysm or dissection early
- Plan open or endovascular surgery
- Monitor stent-graft position and leaks after EVAR
- Track aortic growth in Marfan or bicuspid valve patients
When to Take Test
Benefits
Benefits of Taking the Test
- Zero radiation – safe for repeat follow-ups
- Sub-millimetre resolution in under 30 minutes
- Kidney-safe non-contrast options
- Same-day digital report accessible on our patient app
Conditions Diagnosed
- Aortic aneurysm (thoracic / abdominal)
- Aortic dissection (Stanford A & B)
- Coarctation of the aorta
- Atherosclerotic stenosis and inflammatory vasculitis
Preparing for test
- Fast 4–6 hours if contrast will be used; water is allowed.
- Remove all jewellery, watches, hearing aids.
- Bring previous scans (CT/MRI) for comparison.
- Inform staff about pregnancy or breastfeeding.
Pre-requisites
- Recent creatinine/eGFR report (within 4 weeks) if gadolinium planned
- List of current medications, especially metformin
- Completed MRI safety questionnaire
Best Time to Take MRI Aortic Angiography
- As soon as new symptoms appear—early diagnosis saves lives.
- For known aneurysm: every 6–12 months or as advised by your vascular surgeon.
Eligibility
- Adults and children above 8 years (younger kids need sedation consultation)
- eGFR ≥30 mL/min for contrast studies; no lower limit for non-contrast MRA
Procedure for Taking MRI Aortic Angiography
- Change into cotton gown; locker provided.
- Lie on scanner table; cardiac coil placed over chest/abdomen.
- If contrast is used, IV cannula is inserted and 10–15 mL gadolinium injected halfway.
- You will be asked to hold breath 2–3 times for 15 seconds each.
- Total table time: 20–40 minutes.
- IV line removed; you can resume normal activity immediately.
Caution Before Taking the Test
- Pacemaker/ICD: bring device card; our radiologist will confirm MRI-conditional status.
- Pregnancy: urine β-hCG screening done on site for women of child-bearing age if contrast study planned.
Test Results
Results and Interpretations
| Finding / Observation | Description | General Interpretation/Significance |
|---|---|---|
| Aortic diameter 5.2 cm | Abdominal aortic aneurysm | Refer to vascular surgery |
| Stent graft endoleak type II | Contrast outside graft but within aneurysm sac | Schedule 6-month follow-up |
| Dissection flap in descending aorta | Stanford B dissection | Urgent BP control & surgical review |
| 70 % stenosis at origin of left renal artery | Atherosclerotic stenosis | Consider stent if resistant hypertension |
| Lumen Patency & Flow | Example: High-grade (~70%) stenosis of left renal artery; thrombus in false lumen of dissection. | Identifies critical vessel narrowing (risk of hypertension/organ ischemia) or thrombus formation (complicates dissection). |
| Branch Vessel Ostia | Celiac, superior mesenteric, renal artery ostia patent, no stenosis or dissection flap involvement. | Indicates preserved blood flow to vital abdominal organs despite aortic pathology. |
| Congenital Anomaly | Severe coarctation distal to left subclavian artery with significant velocity gradient and collateral vessels noted. | Confirms congenital narrowing that may require intervention; collaterals indicate chronic compensation. |
| Post-Stent Graft Status | Endovascular stent graft well positioned, no endoleak; aneurysm sac size decreased (e.g., from 5.0 cm to 4.5 cm). | Reflects successful repair with no current complications and favorable remodeling of aneurysm sac. |
Risks & Limitations
- Contrast vs. non-contrast: Gadolinium is avoided if eGFR <30 mL/min; non-contrast 3D-TOF or SSFP sequences are then used.
- Claustrophobia: Our wide-bore 70 cm scanner and headphone music reduce anxiety; oral sedation available on request.
- Metallic implants: Pacemakers, cochlear implants and certain aneurysm clips may be contraindicated—our tech team will run an MRI safety checklist when you book.
FAQs
Is contrast always required?
No. Our 3T system can run non-contrast 3D-SSFP sequences that image the aorta clearly in most patients.
How long does the scan take?
20–40 minutes total, including positioning.
When will I get my report?
Same day by 8 p.m. for scans done before 4 p.m.; next morning for later slots.
Can I eat before the test?
You may have a light meal 4–6 hours earlier if contrast is planned; non-contrast studies have no dietary restriction.
Is the test covered by insurance?
Yes, under most policies as “MRI angiography”; our front desk will assist with pre-authorisation.
What if I am claustrophobic?
If you suffer from claustrophobia (fear of enclosed spaces), please inform the Cadabams Diagnostics staff when you schedule your MRI Aortic Angiography. We understand this concern and can discuss options to help you feel more comfortable. These might include listening to music through headphones, using a blindfold, having a friend or family member in the room (if MRI safe), or, in some cases, your referring doctor might prescribe a mild sedative to take before the scan.
