CT Angiogram
CT Angiography (CTA) uses contrast agents to visualise arteries with remarkable detail. It can assess blood vessels throughout your body – from coronary arteries to those in the brain, neck, lungs, abdomen, and legs. It's essential for detecting blockages, aneurysms, and vascular abnormalities.

Preparation Required
- Avoid food for 4 hours before the scan
- Stay well hydrated (water is encouraged)
- Recent kidney function blood tests are required
- Inform us of any contrast allergies – pre-medication may be necessary
- Metformin may need temporary suspension – consult your doctor
