Computed Tomography Pulmonary Angiography (CTPA)

Computed Tomography Pulmonary Angiography (CTPA) is a specialized imaging test used to visualize the blood vessels in the lungs. It involves injecting a contrast dye into a vein, which makes the blood vessels show up clearly on a CT scan. The scan provides detailed images, helping doctors detect blockages or blood clots in the pulmonary arteries, such as in pulmonary embolism. CTPA is quick, minimally invasive, and highly effective for diagnosing vascular conditions in the lungs, guiding appropriate treatment decisions.
