Why is a pulmonary angiogram performed?

A pulmonary angiogram is performed primarily to visualize the blood vessels in the lungs, particularly the pulmonary arteries and veins. This procedure involves injecting a contrast dye into the blood vessels, allowing healthcare providers to obtain detailed imaging of the vascular structures in the lungs. It is particularly useful for diagnosing conditions such as pulmonary embolism, where a blood vessel in the lung is blocked, as well as other vascular disorders.

Understanding the function of pulmonary angiograms greatly aids in managing patients with suspected vascular complications. This imaging technique provides critical information about blood flow and can guide further treatment decisions.
