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 ]
Abdominal pain. Shortness of breath. Fatigue. Pressure or heaviness in your chest. Sweating. Nausea or vomiting. Dizziness. Pain caused by a heart attack usually persists for more than 20 minutes ...
The rationale behind this decision is that further testing (specifically CT angiogram of the chest) may cause more harm (from radiation exposure and contrast dye) than the risk of PE. [50] The PERC rule has a sensitivity of 97.4% and specificity of 21.9% with a false negative rate of 1.0% (16/1666). [49]
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 ...

Cardiac CT (CCT) is a modified form of the traditional chest CT due to the difficulty of imaging the complex, moving heart. [16] This is achieved through the use of thin slices and high-resolution scanning, as well as the addition of electrocardiogram (ECG) gating or triggering to capture a motion-free image.
