What is Angiography ?
Angiography is an advanced imaging procedure used to examine the arteries and veins for blockages, narrowing, or other abnormalities. A special contrast dye is injected through a thin catheter, allowing blood vessels to be clearly visualized using X-ray imaging.
This safe and effective procedure helps vascular surgeons accurately diagnose vascular diseases and plan the most appropriate treatment.
Types of Angiography
- CT Angiography (CTA) – Uses CT imaging and contrast dye to create detailed images of blood vessels.
- MR Angiography (MRA) – Uses MRI technology to evaluate blood vessels without exposing patients to ionizing radiation.
- Digital Subtraction Angiography (DSA) – A highly precise catheter-based technique commonly used for diagnosing and treating vascular conditions.
- Carbon Dioxide (CO₂) Angiography – An alternative imaging method using carbon dioxide gas instead of contrast dye, especially suitable for selected patients with kidney concerns.
