- Contrast echocardiography is a type of echocardiogram, which is a cardiac ultrasound and can also be called an echo. By adding a contrast, a cardiac echo has better resolution.The additional, clearer resolution allows doctors to watch blood flow through the heart.n echocardiogram is typically performed by an ultrasound technician. Doctors use contrast echocardiography to diagnose a variety of heart issues. An echocardiogram is a specialized type of ultrasound that only documents the cardiac system.

Echocardiagram An echocardiogram uses an ultrasound machine to take a scan of your heart. It is carried out by a specially qualified technician and is sometimes just called an ‘echo’, ‘echo heart’ or ‘echogram’. Ultrasound machines detect sounds with such high frequencies that they cannot be heard by humans. The test is called an echocardiogram because the sound ‘bounces’ or echoes back from the heart tissue to give an accurate picture of the heart. For example, ultrasound passes easily through fluid so there is little echo from the blood in the heart, which would otherwise affect the result.

Echocardiogram An echocardiogram – also known as an echo – uses sound waves to build up a detailed picture of your heart. It is similar to the ultrasound scan used in pregnancy. The echo looks at the structure of your heart and the heart valves, and also gives information on the function and pumping action of your heart. It can be a useful test if you have recently had a heart attack or if you have heart failure.

CT Scan - CT Angiography, CTA Scan When the contrast dye is used to visualize veins, the study is called a venogram, and when it is used to visualize arteries, it is known as an arteriogram. In CT angiogram, the dye is always injected into a vein first and as the dye circulates from the veins into the arteries, images are obtained during both phases. CT angiography is considered less invasive than the traditional angiogram.

Angiogram BY DR. LUKE K. MARONE. An angiogram is an X-ray procedure that can be both diagnostic and therapeutic. It is considered the gold standard for evaluating blockages in the arterial system. An angiogram detects blockages using X-rays taken during the injection of a contrast agent (iodine dye).

- An echocardiogram is a test that uses high-frequency. sound waves (ultrasound) to check your heart. The sound. waves bounce (or “echo”) off structures in your heart, and. the echoes are shown as images on a monitor. A stress echocardiogram compares your heart when it is at. rest and when it is working hard.

Echocardiograms: Transthoracic (TTE) & Transesophageal (TEE) An echocardiogram is essentially a Doppler ultrasound tool. The device emits sound waves, which bounce off the heart’s structures, creating an image of the heart and/or blood vessels under examination. The image yielded by an echocardiogram is more detailed than an x-ray. Also, echocardiograms may be safer since they use sound waves instead of radiation. Another key benefit of an echocardiogram is that the test captures moving images of the heart, allowing the cardiologist to see how the heart pumps blood and how the valves function. Who needs an echocardiogram? An echocardiogram may be ordered for patients who have (or may have): Arterial blockages (heart, neck, abdomen, and elsewhere)

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.

Coronary Computed Tomography Angiogram What is coronary computed tomography angiogram or CTA? A coronary computed tomography angiogram (CTA) uses advanced CT technology, along with intravenous (IV) contrast material (dye), to obtain high-resolution, 3D pictures of the moving heart and great vessels. CTA is also called multi-slice computed tomography (MSCT), cardiac CT or cardiac CAT. During CTA, x-rays pass through the body and are picked up by detectors in the scanner, that produce 3D images on a computer screen.
