Cardiac CT Scan A multidetector CT is a very fast type of CT scanner that can produce high-quality pictures of the beating heart and can detect calcium or blockages in the coronary arteries. An electron beam CT scanner also can show calcium in coronary arteries. Your cardiac CT scan may be performed in a medical imaging facility or hospital. The scan usually takes about 15 minutes to complete, but can take more than an hour including preparation time and, if needed, the time to take medicines such as beta blockers to slow your heart rate.

- a nuclear heart scan is a test that provides important information about the health of your heart for this test a safe radioactive substance called a tracer is injected into your bloodstream through a veinthe tracer travels to your heart and releases energy special cameras outside of your body detect the energy and use it to create pictures of your heart nuclear heart scans are used for three main purposesamage might be the result of a previous heart attack injury infection or medicine when a nuclear heart scan is done for this purpose it s called myocardial viability testing to see how well your heart pumps blood to your body

- An ultrasound scan is a painless test that uses sound waves to create images of organs and structures inside your body. It is a very commonly used test. As it uses sound waves and not radiation, it is thought to be harmless.

Overview Heart scan (coronary calcium scan) Heart scan (coronary calcium scan) A heart scan (coronary calcium scan) provides pictures of your heart's arteries. Doctors may use this test to look for calcium deposits in the coronary arteries that can narrow your arteries and increase your heart attack risk.

- The coronary calcium scan is a preventative test that can ensure that your heart is able to function properly. The arteries in your heart carry blood to the rest of the body, and if these are blocked it can cause heart attacks, strokes, and many other life threatening issues.he coronary calcium scan is a preventative test that can ensure that your heart is able to function properly.

Focus on: CT scans of the heart Focus on: CT scans of the heart Computerised tomography (CT) has been around since the 1970s. There are two ways in which a CT scan can be used for the heart – one is a CT coronary angiogram and the other is a CT calcium score. A CT scan produces multiple images of the heart from different angles, which the doctor can then see on a computer screen.

CT Calcium Score Scan Both use x rays to create detailed pictures of your heart. Your doctor will study the pictures to see whether you're at risk for future heart problems. A coronary calcium scan is a fairly simple test. You'll lie quietly in the scanner machine for about 10 minutes while it takes pictures of your heart.

Cardiac Perfusion Scan Cardiac Perfusion Scan. Guide. A cardiac perfusion scan measures the amount of blood in your heart muscle at rest and during exercise. It is often done to find out what may be causing symptoms like angina (such as chest pain or pressure).hy It Is Done. A cardiac perfusion scan is done to: 1  Find the cause of unexplained chest pain or pressure. 2  Find the cause of chest pain or pressure brought on by exercise. 3  Check for the location and amount of damage caused by a heart attack. 4  Identify coronary artery disease (CAD) .

echocardiography Echocardiography is a diagnostic test that uses ultrasound waves to create an image of the heart muscle. Ultrasound waves that rebound or echo off the heart can show the size, shape, and movement of the heart's valves and chambers as well as the flow of blood through the heart. Echocardiography may show such abnormalities as poorly functioning heart valves or damage to the heart tissue from a past heart attack.

Positron Emission Tomography (PET) 1 A PET scan shows if your heart is getting enough blood or if blood flow is reduced because of narrowed arteries. It also shows dead cells (scars) from a prior heart attack.  A PET scan can help in determining if you’ll benefit from a cardiac procedure (PCI) or surgery to restore blood flow.

Transesophageal Echocardiography (TEE) What is transesophageal echocardiography? Transesophageal echocardiography (TEE) is a test that produces pictures of your heart. TEE uses high-frequency sound waves (ultrasound) to make detailed pictures of your heart and the arteries that lead to and from it.

Diagnosing Heart Disease With Cardiac Computed Tomography (CT) Cardiac CT is a heart-imaging test that uses CT technology with or without intravenous (IV) contrast (dye) to visualize the heart anatomy, coronary circulation, and great vessels (which includes the aorta, pulmonary veins, and arteries). There are several types of CT scans used in the diagnosis of heart disease, including:

Nocturnal Leg Cramps Leg cramps (charley horses) are a common nocturnal symptom that can be difficult to manage because of uncertainties about etiology, appropriate diagnostic evaluation, and optimal treatment. Nocturnal leg cramps are reported by 50 to 60 percent of adults and by approximately 7 percent of children.

Heart CT Scan During the test, a specialized dye will be injected into your bloodstream. The dye is then viewed under a special camera in a hospital or testing facility. A heart CT scan may also be called a coronary CT angiogram, if it is meant to view the arteries that bring blood to your heart. It may be called a coronary calcium scan if it meant to determine whether there is a build-up of calcium in your heart.

The MUGA scan The MUGA scan (MUltiple Gated Acquisition scan) is a noninvasive test used to evaluate cardiac function. The MUGA scan produces a moving image of the beating heart, and from this image several important features can be determined about the health of the left and right ventricles (the heart’s major pumping chambers).

- A heart CT scan is a common test for those experiencing heart problems, since it allows your doctor to explore the structure of the heart and the adjacent blood vessels, without making any incisions.

Positron Emission Tomography (PET) A PET scan is a very accurate way to diagnose coronary artery disease and detect areas of low blood flow in the heart. PET can also identify dead tissue and injured tissue that’s still living and functioning. If the tissue is viable, you may benefit from a PCI or coronary artery bypass surgery.

Diagnosis & Tests CT Heart Scan Computed tomography (CT scan) of the heart can visualize your heart’s anatomy. Calcium-score heart scan and coronary CT angiography are just a few types used to diagnose heart disease. Myocardial Biopsy A myocardial biopsy is when a doctor uses a special catheter to remove a piece of your heart tissue for examination.

(A-Z) All Cardiac computed tomography (to-MOG-rah-fee), or cardiac CT, is a painless test that uses an x-ray machine to take clear, detailed pictures of the heart. Doctors use this test to look for heart problems. During a cardiac CT scan, an x-ray machine will move around your body in a circle.The machine will take a picture of each part of your heart. A computer will put the pictures together to make a three-dimensional (3D) picture of the whole heart.uring a cardiac CT scan, an x-ray machine will move around your body in a circle.
