A CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries. Its main use is to diagnose pulmonary embolism (PE). [ 1 ]
Pulmonary angiography is useful as the confirmation test where the non-invasive imaging such as CT pulmonary angiography is inconclusive on determining the presence of pulmonary embolism. [1] The accuracy of pulmonary angiography may be higher than clinical examination, arterial blood gas results, and ventilation/perfusion scan. [2]
Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography—the visualization of arteries and veins—throughout the human body. Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of walls ...
CT pulmonary angiogram, which uses time-matched ("phased") protocols to assess the lung perfusion and the patency of great arteries and veins, particularly to look for pulmonary embolism. [ 1 ] References
Pulmonary angiography is the gold standard for diagnosis of pulmonary artery agenesis. [18] It is an invasive method that directly demonstrates the absence of one of the pulmonary arteries through the injection of a contrast dye into the blood. [23] Magnetic resonance angiography (MRA) can be employed to assess the haemodynamic status in real ...
Blood tests, a CT angiogram, and ultrasounds can help diagnose PE, according to the Cleveland Clinic. You might also need a pulmonary angiogram or chest x-ray. PE is usually treated via ...
