CTPA was introduced in the 1990s as an alternative to ventilation/perfusion scanning (V/Q scan), which relies on radionuclide imaging of the blood vessels of the lung. It is regarded as a highly sensitive and specific test for pulmonary embolism. [1] CTPA is typically only requested if pulmonary embolism is suspected clinically.
A CT pulmonary angiogram, in this case showing pulmonary embolism of saddle-type, which becomes more radiolucent than the radiocontrast filled blood surrounding it (but it may be indistinguishable without radiocontrast). Contrast CT, or contrast-enhanced computed tomography (CECT), is X-ray computed tomography (CT) using radiocontrast.
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 ...
Computed tomography angiography (CTA) is a type of contrast CT to visualize the arteries and veins throughout the body. [47] This ranges from arteries serving the brain to those bringing blood to the lungs, kidneys, arms and legs. An example of this type of exam is CT pulmonary angiogram (CTPA) used to diagnose pulmonary embolism (PE).
