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 ...

Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
Pronunciation follows convention outside the medical field, in which acronyms are generally pronounced as if they were a word (JAMA, SIDS), initialisms are generally pronounced as individual letters (DNA, SSRI), and abbreviations generally use the expansion (soln. = "solution", sup. = "superior").
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).
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. If the probability of PE is considered low, a blood test called D-dimer may be requested. If this is negative and risk of a PE is considered negligible, then CTPA or other scans are ...
must hold a current, unrestricted practical/vocational nurse license in the United States or its territories and must have hospice and palliative licensed practical/vocational nursing practice of 500 hours in the most recent 12 months or 1000 hours in the most recent 24 months prior to applying for the examination.
Cystine tryptic agar (CTA), also known as cystine trypticase agar, [1] [2] is a growth medium used for the identification of microorganisms. [ 3 ] It can be used to determine if organisms can ferment various carbohydrates , including maltose , lactose , and sucrose .
