CT Peripheral Angio

• Purpose: Visualise arteries in the arms and legs to locate blockages, clots, or narrowing.
• Technology: 128-slice CT with ultra-low-dose radiation.
• Time: 15–30 minutes total appointment.
• Result Turnaround: Digital reports delivered within 3 hours.

CT Peripheral Angio combines X-rays and computer processing to create cross-sectional images of blood vessels. After a small IV injection of iodine-based contrast dye, the CT scanner rotates around the limb, capturing hundreds of slices. These are reconstructed into detailed 3-D images that reveal:

• Plaque build-up
• Blood clots
• Aneurysms
• Vascular malformations

• CT Aortogram with Run-off: From abdomen to toes in one sweep
• Upper Limb CT Angio: Focus on arms and hands
• Lower Limb CT Angio: Focus on legs and feet
• Bilateral vs Unilateral: Depending on symptoms

• Confirm peripheral artery disease (PAD)
• Rule out deep vein thrombosis (DVT)
• Evaluate traumatic vascular injuries
• Monitor bypass graft patency
• Detect vasculitis (e.g., Buerger’s disease)

Your doctor may order the scan if you have:

• Claudication (cramping leg pain while walking)
• Non-healing ulcers on feet or toes
• Cold or discoloured extremities
• Diabetes with suspected peripheral artery disease (PAD)
• Pre-surgical planning before bypass or angioplasty

• Non-invasive: No catheter insertion into arteries
• Fast: Clear 3-D images in minutes
• Accurate: Detects even 30 % narrowing
• Guidance: Helps plan stent, balloon, or bypass
• Peace of mind: Know the exact location and severity of disease

• Atherosclerosis
• Peripheral artery disease (PAD)
• Embolism
• Arteriovenous malformations (AVM)
• Popliteal artery entrapment syndrome
• Diabetic foot vasculopathy

• Fasting: 4 hours before scan (sips of water allowed)
• Clothing: Wear loose attire; we provide a gown
• Jewellery: Remove all metal below the chest
• Diabetes: Hold metformin on scan day; bring recent creatinine report

• Referral note from your doctor
• Creatinine/eGFR (within 4 weeks if > 60 y or at risk)
• Previous imaging CDs for comparison, if any

• Morning slots preferred to maintain 4-hour fast
• Emergency cases: 24/7 availability at Cadabams Diagnostics
• Follow-up: 3–6 months post-intervention or as advised

Eligible

• Adults 18 y and above
• Stable vitals
• eGFR ≥ 45 mL/min/1.73 m² May need alternative imaging
• Pregnancy
• Severe iodine allergy
• eGFR < 30 (consider CO₂ angiography)

1. Check-in: Front desk verifies ID and consent.
2. IV line: 20-gauge cannula in the antecubital vein.
3. Positioning: Lie supine, arms above head for lower-limb scan.
4. Contrast injection: 80–100 mL at 4–5 mL/s; warm sensation is normal.
5. Scan: 5–10 seconds of breath-hold while table moves.
6. Observation: 15-minute post-scan monitoring for any delayed reaction.
7. Home: Resume normal diet and medications.

• Pregnancy test if female and < 50 y
• Asthma or prior contrast reaction—notify technician
• Kidney concerns—carry latest serum creatinine report
• Pacemaker/implants—inform staff; most are CT-compatible
