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.

An example of this type of exam is CT pulmonary angiogram (CTPA) used to diagnose pulmonary embolism (PE).
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.
