MR Angiogram (MRA) Studies at Madras Scans & Labs

Madras Scans & Labs offers high-resolution 3T MR Angiography (MRA), a non-invasive, radiation-free alternative to conventional angiography for detailed vascular imaging.

Types of MR Angiogram Studies

1. Cerebral MRA (Brain Vessels)

• Detects:

  • Aneurysms, AVMs, arterial stenosis

  • Vasculitis (e.g., PACNS) & Moyamoya disease

• Techniques:

  • Time-of-Flight (TOF-MRA) – No contrast needed

  • Contrast-Enhanced (CE-MRA) – Higher accuracy

2. Neck MRA (Carotid & Vertebral Arteries)

• Evaluates:

  • Carotid artery stenosis (stroke risk assessment)

  • Vertebral artery dissection

  • Vascular compression in cervical spine

3. Thoracic & Abdominal MRA

• Aortic MRA:

  • Aneurysms, dissections, coarctation

• Renal MRA:

  • Renal artery stenosis (hypertension workup)

• Mesenteric MRA:

  • Chronic mesenteric ischemia

4. Peripheral MRA (Arms/Legs)

• Assesses:

  • Peripheral arterial disease (PAD)

  • Popliteal artery entrapment

  • Diabetic foot vasculopathy

5. Coronary MRA (Non-Invasive Heart Vessels)

• For patients who cannot undergo CT angiography

• Detects coronary anomalies, aneurysms (Kawasaki disease)

Advanced MRA Techniques

✔ 4D Flow MRI – Measures blood flow dynamics (e.g., aortic regurgitation)
✔ Black-Blood MRA – Better plaque characterization
✔ Time-Resolved MRA – Tracks contrast bolus in real-time

Why Choose 3T MRA at Madras Scans & Labs?

✅ No Radiation – Safer than CT angiography (CTA)
✅ Superior Soft-Tissue Contrast – Better vessel wall imaging
✅ Non-Invasive – No catheterization required
✅ Expert Vascular Radiologists – Precise stenosis measurements

Indications:

• Stroke/TIA evaluation

• Unexplained hypertension (renal artery screening)

• Pre-surgical vascular mapping

Scan Duration: 15-30 mins (varies by region)

Contact for:

• Pediatric MRA (Congenital vascular malformations)

• Second opinion reviews
