Understanding CT Angio- Pulmonary Venous Anatomy

What is CT Angio- Pulmonary Venous Anatomy?

The CT (Computed Tomography) Angio - Pulmonary Venous Anatomy is a procedure that conducts a detailed observation of the pulmonary veins. Pulmonary veins are those which carry oxygen-rich blood from the lungs to the heart.

This procedure helps detect any blockages in the veins. It is also used to detect congenital diseases, blockages in the blood vessels, increase in blood pressure, and obstruction in arteries caused by blood clots. It helps examine cancerous mass and pulmonary tumors. It can also help examine the veins for hardening caused by calcium carbonate.

A contrast material is injected into the veins, after which the rotating beams of X-Rays capture a detailed image of the veins. Pregnant women must inform the doctor before the procedure to avoid exposing the fetus to radiation.
