Nuclear Stress Test Radiation Exposure
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
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
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
Talk to your doc...: It is quite normal to be apprehensive about the test and potential side effect of med/material you are given. The substances often used in nuclear stress test is called thallium-201 or technetium-99 radioactive isotopes. The amount used is quite small and long-term cancer risk is less than 1 in 1000 in older adults. I recommend discussing your concern with your doc. Good luck. ...Read moreSee 2 more doctor answers
Why do I have to avoid my 1 month old granddaughter and a running microwave for the next 3 days after a nuclear stress test? Are my little dogs at ri
Who said that?: Your granddaughter and your dog get more radiation in the basement of a newly built house than they could possible get from you after a cardiac nuclear stress test. If you were given a Technetium 99m product with your test than the radiation is effectively completely gone in 24 hours, and is barely detectable outside of your urine the same day. You were given poor advice. ...Read more
I recently had an echocardiogram that revealed either an asd or pfo. No further tests have been done yet. The md wants me to have a nuclear stress test. Is this safe?
Cardiac ct scan results dr said pictures weren't very good.
Wants me to get a nuclear stress test. Would it be feasible to ask for another CT scan?
Unadvised but possib: Getting another CT scan is 99% likely to give the same picture as the 1st, barring an obvious problem (like the machine broke down, which they would have informed you at the site). Another modality is more likely to provide information than repeating the same test. CT scans involve lots of radiation, & show calcium deposits & perhaps blood flow, but not if heart is affected. The Nuc stress will. ...Read more
Nuclear stress test results came back normal. However, i'm still feeling symptoms. Am I just being dumb? Should I just be content w/the results?
Typically not: The only "risk" would be during the stress part, when one runs on a treadmill or gets a drug alternative. However, there is little risk here because this is monitored with an ekg and supervised by a cardiologist/nuclear physician. One drug that is used for stress even has an agent that can reverse its side effects. In summary, under normal standard-of care-conditions, there should be little risk. ...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
Irradiation is the process by which an object is exposed to radiation. The exposure can originate from various sources, including natural sources. Most frequently the term refers to ionizing radiation, and to a level of radiation that will serve a specific purpose, rather than radiation exposure to normal ...Read more
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. They can also do a chemical stress test which omits the need to ...Read more
