About CT Coronary Angiography:
Computed tomography (CT) Coronary angiography is a type of X-ray imaging procedure that uses contrast dye, a CT scanner, and a computer to create images of the heart and blood vessels (coronary arteries).
With the help of CT Coronary Angiography test, it is known about the narrowing and blockage in the coronary arteries. Iodine-based contrast dye is used in CT coronary angiography. When dye is used in a CT coronary angiography test, the picture of the heart and its blood vessels is seen more clearly.
Coronary arteries can become narrowed and blocked due to a build-up of plaque (excess of fat, cholesterol and calcium).
whistle. Who can't have Monography?
Pregnant women should avoid CT coronary angiography, as it may harm the unborn baby. Contrast dye scan is not done in people with diabetes or those with kidney disease.
whistle. Why go to angiography?
Doctors recommend signing notes in the following signatures:
Chest pain but other test results like ECG are normal
Nuclear cardiac stress test (measures the electrical activity of the heart during exercise on a treadmill or while riding a bicycle)
unusual chest pain
acute heart failure with reduced cardiac function
risk of coronary artery disease
whistle. How should one prepare for the monography?
You need to go to the hospital wearing loose and comfortable clothes. However, many hospitals may provide you with a gown before the test. Jewelry, hearing aids, and any metal on dentures should be left at home or removed before the test. The doctor may give you information about the test and ask you to sign a consent form.

The doctor may ask you to stop taking diet pills, caffeinated drinks like tea, coffee, and certain medicines that can interfere with the test results. They may prescribe beta-blocker medication to take the night before the test to slow the heart rate.
What is the process of CT signalography?
Following are the methods of CT ablative angiography procedure:
Firstly you will be asked to remove all type of jewellery, metal objects like keys, belts, rings.
You may then be asked to lie on a scanning table, which will slowly move inside a tunnel-like part of the scanning machine.
The technologist will place small electrodes (sticky discs) on your chest, which will be connected to an electrocardiograph (ECG) monitor to show heart activity.
He will inject contrast dye into a vein in your arm. They may give a beta-blocker intravenously or orally during this time.
They may also give another medicine (in tablet form) called nitroglycerin, which helps make the arteries look wider and clearer. However, this medicine may also be given as a sublingual spray.
The machine will start once the dye reaches your heart.
To improve image quality, you may be asked to raise your arms above your head during the scan.
When pictures are being taken, the table can slowly slide in and out of the scanner and you will find that the machine is moving around you.
The technologist will operate the machine from another room. If you want to communicate with them, you can do so through the speaker and mic inside the machine.
You may also be asked to lie down and hold your breath for five to 15 seconds while the scanner captures the images.
The IV line will be removed after the test.
The CT coronary angiography test usually takes about 15 minutes.
whistle. What does related angiography feel like?
CT coronary angiography is a painless test. However, the process may feel a bit uncomfortable.
The contrast dye is injected with a needle, so some people may have discomfort from the sting of the needle. In addition, you may experience a warm mouth, a metallic taste, or sweating when the dye is injected.
Beta-blockers can cause dizziness in some people. Apart from this, sounds like whistling or clicking can also be heard from the machine. If you are scared of these sounds, you can ask for earplugs.
What do CT linear angiography results indicate?
The CT sinography test detects blockages in the signal path. It gives the following information:
how many blocked arteries
where is the block
severity of obstruction
Benefits of Whistle Messaging:
It is a non-invasive test and provides detailed images of the coronary arteries.
X-ray radiation does not remain in the body after the test.
Risks of CT Description Angiography :
Contrast dye can be harmful to people with kidney disease.
Contrast dye causes allergic reactions in some people.
What happens after CT coronary angiography?
Unless otherwise advised by the doctor, you can continue with your normal activities after the test. You may need to drink a lot of water to help flush the dye out of your body.
What other tests may be done along with CT coronary angiography?
