Exame medicina nuclear stress test interpretation

Your doctor has ordered a nuclear medicine stress test for younow what? Here's what to expect and how to get ready for your exam. Nuclear medicine has long played an important role in the noninvasive evaluation of known or suspected coronary artery disease. The sensitivity of exercise stress testing ranges from 23 to 100 percent, and the specificity ranges from 17 to 100 percent. Nuclear medicine examinations provide unique informationincluding details on the function and anatomy of body structuresthat is often unattainable using other imaging procedures.

The completed exam consists of intravenous access, resting images, a stress test (performed by use of a medication- no exercise or treadmill), and stress imaging. The European Society of Cardiology (ESC) is an independent, nonprofit organisation aiming to reduce the burden of cardiovascular disease. The nuclear stress test is most often performed to help diagnose whether coronary artery disease is the cause of unexplained symptoms, especially episodes of chest pain or dyspnea. Because the vast majority of all exercise stress tests in the United States are performed using a treadmill, the term treadmill test has almost become synonymous with exercise stress test.

Our team of cardiac imaging physicians, nurse practitioners, technologists, and ECG technologists is headed by Daniel Berman, MD, chief of Cardiac Imaging and Nuclear Cardiology. This new diagnostic methodology managed to assess fetal monitoring objectively and reproducibly, establishing differences between monitorings with normal and abnormal patterns, and the. Performed commonly on a treadmill or a stationary cycle, the test is useful in diagnosing coronary artery disease (CAD) , a condition often missed when a person is at rest. In practice, maximum VO 2 (VO 2 max) is defined as the highest value reached, despite progressive increase of the load applied, with the development of a plateau in the VO 2.



A MUGA scan is a test using a radioactive tracer (called a radionuclide) and a special camera to take pictures of your heart as it pumps blood


The development of single photon emission computed tomography (SPECT) led to improved assessments of myocardial perfusion, and the use of electrocardiographic gating made accurate measurements of ventricular wall motion, ejection fractions, and ventricular volumes

The amount of time between administration of the tracer and the taking of the images may range from a few moments to a few days. A nuclear stress test is very similar to a regular stress test, except it also includes imaging of your heart and radioactive dye in your veins. Compared with an exercise stress test, a nuclear stress test can help better determine your risk of a heart attack or other cardiac event if your doctor knows or suspects that you have coronary artery disease. A nuclear medicine scan consists of 3 phases: tracer (radionuclide) administration, taking images, and image interpretation.
