Coronary CT angiography

Coronary CT angiography (CCTA) is the use of CT angiography to assess the arteries of the heart.
Coronary CT angiography (CTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.

CT pulmonary angiogram

CT pulmonary angiogram (CTPA) is used to examine the pulmonary arteries in the lungs, most commonly to rule out pulmonary embolism (PE), a serious but treatable condition.
CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries.

Aneurysm

aneurysmsaneurismruptured aneurysm
Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of walls), and stenosis (narrowing of vessel).
Computed tomography angiography (CTA) is an alternative to traditional angiography and can be performed without the need for arterial catheterization.

Angiography

angiogramarteriographyangiographic
Today, many patients can undergo CTA in place of a conventional catheter angiogram, a minor procedure during which a catheter is passed through the blood vessels all the way to the heart, however CCTA has not fully replaced this procedure.
The term angiography has been applied to radionuclide angiography and newer vascular imaging techniques such as CT angiography and MR angiography.

Aortic dissection

CTA is also used to identify dissection in the aorta or its major branches.
If there is high clinical suspicion, a more sensitive imaging test (CT angiogram, MR angiography, or transesophageal echo) may be warranted.

Contrast CT

CT angiography is a contrast CT where images are taken with a certain delay after injection of radiocontrast material.
CT angiography is a contrast CT taken at the location and corresponding phase of the blood vessels of interest, in order to detect vascular diseases.

Magnetic resonance angiography

Stenosis

Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of walls), and stenosis (narrowing of vessel). While CTA can produce high quality images of the carotid arteries for grading the level of stenosis (narrowing of the vessel), calcium deposits (calcified plaques) in the area where the vessels split can lead to interference with accurate stenosis grading.
