coronary CT angiography (CTA)

Coronary CT angiography (CTA) is a medical imaging technique that uses a CT scanner to create detailed pictures of the heart's blood vessels. During the procedure, you receive an injection of a contrast dye, which helps highlight the coronary arteries. The scanner captures images while you hold your breath briefly, allowing doctors to assess for blockages or narrowing that could lead to heart disease. CTA is a non-invasive test, meaning it doesn't require surgery, and can provide valuable information for diagnosing heart conditions and planning treatment.
