CT Pulmonary Angiography – Purpose & Procedure

CT Pulmonary Angiography (CTPA) is a specialized CT scan that provides detailed images of the blood vessels in your lungs. It’s primarily used to detect or rule out pulmonary embolism (PE) — a condition where blood clots block the arteries in the lungs.

The scan uses contrast dye (injected into a vein) and computed tomography (CT) imaging to visualize pulmonary arteries, helping doctors diagnose clots, vascular abnormalities, or other lung-related issues with high accuracy.

Why is CT Pulmonary Angiography Done?

Doctors may recommend a CTPA if you experience symptoms such as:

• Sudden shortness of breath

• Chest pain that worsens with breathing

• Rapid heartbeat or unexplained fatigue

• Low oxygen levels

It helps detect:

• Pulmonary embolism (PE)

• Aneurysms in pulmonary arteries

• Congenital heart or lung vessel defects

• Vascular malformations

CT Pulmonary Angiography Procedure

Here’s what typically happens during a CT Pulmonary Angiography scan:

1. Preparation: You may be asked to fast for 4–6 hours before the test. Remove all metal objects before the scan.

2. Contrast Injection: A contrast dye is injected into a vein (usually in the arm) to make the blood vessels visible.

3. CT Scan: You’ll lie on a table that moves through the CT scanner. The scan usually takes 5–10 minutes.

4. Post-Scan Care: You can resume normal activities afterward. Drink plenty of water to help flush out the contrast material.
