Pulmonary Angiography is a specialized medical imaging technique designed to visualize the blood vessels within the lungs with exceptional precision. This diagnostic procedure involves injecting a contrast agent directly into the pulmonary vasculature to create detailed images of the pulmonary arteries and veins, enabling healthcare professionals to detect and evaluate various cardiovascular and respiratory conditions. Typically performed using computed tomography (CT) technology, pulmonary angiography is particularly crucial in diagnosing potentially life-threatening conditions such as pulmonary embolism, where blood clots obstruct the lung’s blood vessels. The examination requires careful patient preparation, including assessment of renal function and potential contrast allergies, and involves intravenous contrast injection followed by rapid image acquisition. During the procedure, patients are positioned carefully, and a contrast medium is administered to highlight the intricate network of blood vessels, allowing radiologists to identify abnormalities like blood clots, vascular malformations, arterial narrowing, or structural anomalies. The imaging provides cross-sectional views that reveal detailed information about blood flow, vessel diameter, and potential blockages, making it an invaluable diagnostic tool in managing conditions like deep vein thrombosis, chronic pulmonary hypertension, and certain congenital heart defects. While the procedure carries minimal risks, potential complications can include allergic reactions to contrast media, radiation exposure, and rare instances of kidney function impairment, necessitating thorough pre-examination screening and patient monitoring.
