CT Pulmonary Angiography (CTPA) is an advanced radiological technique primarily used to visualize the pulmonary arteries and diagnose conditions like pulmonary embolism (PE). In the context of cancer, CTPA becomes crucial due to the increased risk of thromboembolic events in cancer patients. The procedure involves the injection of a contrast agent to enhance the visibility of blood vessels in the lungs, which is then captured using computed tomography (CT) imaging.
