Why Is CT Pulmonary Angiography Done?
CTPA is recommended when symptoms raise suspicion of pulmonary embolism or other lung vessel diseases. Common symptoms include:
- Sudden shortness of breath
- Sharp chest pain that worsens during breathing
- Rapid heart rate
- Unexplained cough or coughing up blood
Doctors also use CTPA to:
- Evaluate lung circulation issues
- Detect vascular abnormalities or tumors
- Guide treatment planning for pulmonary conditions
How the CT Pulmonary Angiography Test Works
- Preparation: You may be asked to fast for a few hours. A contrast dye is injected into a vein, usually in your arm.
- Scanning: You’ll lie on a CT table that moves through the scanner. While the dye travels through your bloodstream, the scanner captures detailed images of the lungs and pulmonary vessels.
- Results: Radiologists analyze the images for blockages, narrowed vessels, or irregular blood flow patterns. The results are typically sent to your doctor within a short time.
The procedure takes around 15–30 minutes and is usually painless.
Benefits of CT Pulmonary Angiography
- Fast and accurate diagnosis of pulmonary embolism
- Non-invasive and safe imaging technique
- Provides detailed 3D images for precise evaluation
- Helps rule out other lung conditions mimicking similar symptoms
Risks and Precautions
Although CTPA is safe, patients with kidney disease, iodine allergies, or pregnancy should inform their doctor beforehand. Proper hydration before and after the test helps flush out the contrast material effectively.
