Single Photon Emission Computed Tomography (SPECT) The pictures will help your doctor see if your heart is getting enough blood or if blood flow is reduced because of narrowed arteries. A SPECT scan can be used to examine blood flow in your heart at rest and during exercise (called a nuclear stress test). If you can’t exercise, you’ll get a medicine to increase the blood flow in your heart as if you were exercising (called a chemical or pharmacologic stress).

Single-photon emission computed tomography SPECT imaging is performed by using a gamma camera to acquire multiple 2-D images (also called projections), from multiple angles. A computer is then used to apply a tomographic reconstruction algorithm to the multiple projections, yielding a 3-D data set.

Cardiac stress test Cardiac stress tests compare the coronary circulation while the patient is at rest with the same patient's circulation during maximum physical exertion, showing any abnormal blood flow to the myocardium (heart muscle tissue). The results can be interpreted as a reflection on the general physical condition of the test patient.

- Exercise Stress Test Introduction. A stress test can be used to test for heart disease. Stress tests are tests performed by a doctor and/or trained technician to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia (not enough blood flow to the heart muscle).

Fetal Non-Stress Test (NST) The Fetal Non-Stress test is a simple, non-invasive test performed in pregnancies over 28 weeks gestation.The test is named “non-stress” because no stress is placed on the fetus during the test. nonreactive non-stress result requires additional testing to determine whether the result is truly due to poor oxygenation, or whether there are other reasons for fetal non-reactivity (i.e. sleep patterns, certain maternal prescription or nonprescription drugs).

Overview A single-photon emission computerized tomography (SPECT) scan lets your doctor analyze the function of some of your internal organs.A SPECT scan is a type of nuclear imaging test, which means it uses a radioactive substance and a special camera to create 3-D pictures.While imaging tests like X-rays can show what the structures inside your body look like, a SPECT scan produces images that show how your organs work.For instance, a SPECT scan can show how blood flows to your heart or what areas of your brain are more active or less active. 1  Why it's done. single-photon emission computerized tomography (SPECT) scan lets your doctor analyze the function of some of your internal organs.

- A stress test, also called an exercise stress test, gathers information about how your heart works during physical activity. Because exercise makes your heart pump harder and faster than usual, an exercise stress test can reveal problems within your heart that might not be noticeable otherwise.

Single-photon emission computed tomography Animation of a SPECT scanning procedure. Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera. However, it is able to provide true 3D information.

Cardiac stress test Cardiac stress test. A cardiac stress test (or cardiac diagnostic test) is a cardiological test that measures a heart's ability to respond to external stress in a controlled clinical environment. The stress response is induced by exercise or by drug stimulation.

Congestive Heart Failure A nuclear stress test is a noninvasive means of detecting the presence and/or signiﬁ cance of coronary. artery disease. Coronary artery disease is a condition in which there is narrowing or blockage of the blood. vessels supplying the heart muscle. This can cause chest pain which is known as angina pectoris.

Nuclear stress test A nuclear stress test is one of several types of stress tests that may be performed alone or in combination. 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.

Stress Testing/Stress Echocardiogram A stress echocardiogram is a non-invasive test that combines two tests--a treadmill stress test (TST) and an echocardiogram (ECHO). This test is used to see how the heart muscle contracts during rest and during exercise. A stress echo is made up of three parts: a resting echo study, a stress test, and a repeat echo while the heart is beating fast.

Overview A stress test, also called an exercise stress test, shows how your heart works during physical activity. Because exercise makes your heart pump harder and faster, an exercise stress test can reveal problems with blood flow within your heart. A stress test usually involves walking on a treadmill or riding a stationary bike your heart rhythm, blood pressure and breathing are monitored. Or you'll receive a drug that mimics the effects of exercise.

- The nuclear stress test is an assessment of blood ﬂ ow to the heart. This assessment is done in two parts, at rest and during stress. The ﬁ rst step will involve the insertion of an IV for the administration of the sestamibi (Cardiolite) and the. Adenosine if you are having a chemical stress test.

Insulin stress test You will also be asked to give consent for the procedure on the day of the test. The insulin stress test is designed to measure the function of the pituitary gland under stress. This is achieved by obtaining blood samples for hormone measurement, through a small tube (cannula) inserted into a vein in your arm.

Top 20 Doctor insights on: Echocardiogram Vs Nuclear Stress Test Stress Test (Definition) A stress test is a cardiac test which can include walking on a treadmill and monitoring your heart while you are walking. They can also inject you with a nuclear material and do a more comprehensive scan on your heart to check for blockage.

Why Insults HurtâAnd Why They Shouldnât Follow @TIMEIdeas. I became interested in the social function of insults while doing research on the Stoic philosophers, who spent a lot of time thinking about how best to deal with them. I thought this was an odd thing for philosophers to do, but ultimately realized that they were on to something.

Nuclear Cardiac Stress Test Your doctor has suggested you have a Nuclear Cardiac Stress Test. A Cardiac Stress Test is a test to show how your heart functions when your heart rate is increased. You will exercise or be given a certain medicine to increase your heart rate. A Nuclear Cardiac Stress test is a specialized test. A very small amount of a radioactive tracer is given in an IV.
