The CT scanner is a large, tunnel-like machine that has a table. You may feel some discomfort from the needle or, after the contrast dye is injected, you may feel a warm flush briefly throughout your body or have a temporary metallic taste in your mouth. This contrast dye highlights your blood vessels and creates clearer pictures. Before the test, a healthcare provider will inject a contrast dye, often iodine-based, into a vein in your arm. However, it can take more than an hour to prepare for the scan, including time to take medicines such as beta blockers to slow your heart rate or nitroglycerin to help dilate your arteries. The scan itself usually takes only about 15 minutes. You may go to a medical imaging facility or a hospital for a cardiac CT scan. This test may also be used to check the results of coronary artery bypass grafting or to follow up on abnormal findings from earlier chest X-rays. This imaging test can help doctors find heart diseases or problems with the heart or blood vessels supplying blood to the heart or the rest of the body.

Computers can combine these pictures to create a three-dimensional (3D) model of your whole heart. Cardiac CT scanĪ cardiac computed tomography (CT) scan, also called a "CAT scan,” is a painless, non-invasive imaging test that uses X-rays to take many detailed pictures of your heart and its blood vessels. Heart imaging tests take pictures of your heart or its arteries or blood vessels to help your doctor see whether there are any problems. Patricia Bandettini, MD, NHLBI Division of Intramural Research This allows med­ical providers to see a clear, more accu­rate visu­al of the heart’s func­tion­al­i­ty, as well as diag­nose and treat patients at a faster rate.Ĭlick here to learn more about our new Car­diac Eval­u­a­tion Center.Image of cardiac MRI courtesy of W. Since those who usu­al­ly need a heart scan typ­i­cal­ly have irreg­u­lar heart rates, the Car­dio­Graphe scan is designed to cap­ture a pho­to of a sin­gu­lar heart­beat, while still col­lect­ing the full 3D image. Tra­di­tion­al CT scans typ­i­cal­ly com­bine a series of x‑rays to pro­duce a 3D image where­as the Car­dio­Graphe takes a com­plete pho­to in a sin­gle 0.24 sec­ond rota­tion. This scan is faster at pro­duc­ing 3D results com­pared to tra­di­tion­al CTs and uses low­er dose radi­a­tion. This infor­ma­tion is essen­tial in help­ing med­ical providers make thor­ough diag­noses and cre­ate per­son­al­ized treat­ment plans.Ĭar­dio­Graphe is a CT scan that was designed specif­i­cal­ly for car­dio­vas­cu­lar diag­noses. A CT scan shed light on the heart’s health, pro­vid­ing a clear pic­ture of the coro­nary arter­ies, heart mus­cle, peri­cardi­um, pul­monary veins and tho­racic and abdom­i­nal aor­ta. Car­dio­Graphe TM CT ScanĬT scans are designed to diag­nose many dis­eases and injuries to var­i­ous parts of the body, includ­ing the heart. Find out how the Car­dio­Graphe CT scan, used at our Car­diac Eval­u­a­tion Cen­ter, is a game chang­er in diag­nos­ing var­i­ous heart conditions. A com­put­ed tomog­ra­phy (CT) scan is often used to detect under­ly­ing prob­lems that cause symp­toms such as chest pain, short­ness of breath, indi­ges­tion or heart pal­pi­ta­tions. As heart dis­ease con­tin­ues to be the lead­ing cause of death in the Unit­ed States, seek­ing med­ical atten­tion ear­ly for any pos­si­ble heart-relat­ed symp­toms is crit­i­cal.
