Nuclear Stress Testing
Is nuclear stress testing or echo more accurate for calculating ejection fraction? Nuclear says 67 percent echo says 48.
Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger. These stress responses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern. Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn ...Read more
Do I need to have any more testing for blockages with a negative nuclear stress test? Or is this sufficient?
back in may i had a nuclear stress test results could not determine if the image was a breast artifact or something else and a PET scan was warranted .. in other testing he had done the same day ischemia was found .. when went for follow-up he said i did
SPECT vs. PET: On regular myocardial perfusion SPECT imaging, large breasts and large body habitus can cause attenuation artifacts. This is often avoided on cardiac PET where attenuation correction is used. If the breast shifts between stress and rest SPECT imaging, false positive for ischemia could occur. ...Read moreSee 1 more doctor answer
Will a nuclear stress test make me radioactive? I’m having a nuclear stress test, and i need to know if it’s safe for me to babysit my grandkids after it? Will i be radioactive? Could i be dangerous to the kids?
You : You will be sufficiently radioactive to set off alarms at airports, ferry terminals, and border crossings. The sensitivity of these devices is high on purpose. However, the amount of radiation a patient emits after a cardiac nuclear scan is not considered dangerous to others. Notice that the technologists who perform these tests do not wear lead or other radiation protection and they are around "radioactive" patients every day. For the sake of completeness, however, i will add that pregnant women should not undergo this test and anyone who thinks they might be pregnant should have a pregnancy test before having any kind of radionuclide scan. ...Read moreSee 1 more doctor answer
YES...: Nuclear stress tests can be false. The two main types of nuclear stress tests are cardiac pet and cardiac spect. Cardiac pet uses ct for attenuation correction which helps get rid of attenuation artifacts which can cause false results. Cardiac spect is often done without ct and therefore often has more artifacts. The radiotracer used (technetium vs. Thallium) also affects the image quality. ...Read more
Nuclear stress test: The patient walks on a treadmill or other exercise device or has a medication injected to simulate exercise, when the exercise or medicine is in progress a radioactive agent is injected which goes into the heart and can be imaged to show the blood flow into the heart muscle. The information shows if enough blood gets into the heart muscle and other information. ...Read more
Myocardial scan: A cardiac perfusion scan measures the amount of blood supplied to your heart muscle. Radiotracers such as thallium or technetium sestamibi (cardiolite) are injected intravenously and travel through blood to heart muscle.2 sets of images are made during rest and exercise and compared. Indications for this study include chest pain, previous heart attack, heart surgery and coronary artery disease ...Read more

Stress test: A nuclear stress test detects blood supply to the heart. A radioactive tracer is injected into the veins at peak exercise or with a vasodilator. The tracer is taken up by the heart cells and the uprake is proportional to blood flow. By comparing uptake at rest versus exercise we can determine if blood flow is compromised. ...Read moreSee 1 more doctor answer
Echo EF is 60 calculated, 55 visual estimate, and 63 on nuclear stress test. What's most accurate?
How often can nuclear stress test be safely repeated, would doing two tests in 4 month be safe. Any radiations concerns. ?
No sig danger: The amount of radiation is pretty minimal. If its indicated, it should be fine but why repeat it after only 4 months? ...Read more
How long does it take to get results back from a nuclear stress test? I had one two weeks ago for some symptoms, and haven't recieved a call yet?
