Nuclear Isotope Stress Test
Is it ok to have unprotected sex after nuclear perfusion stress test? I was given nuclear isotope radiation. Staff advised me to wait 6 weeks
Sex after radiation: The concerns are for sperm and then abnormal babies resulting from that sperm. If advised to wait 6 weeks you should wait 6 weeks. Otherwise the only way to minimize risk is to make sure that you use condoms- even then that is not a guarentee to prevent problems. ...Read moreSee 1 more doctor answer
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

Radiation exposure: There most certainly is radiation exposure with nuclear cardiology stress testing whether it is with thallium, sestamibi, or any of the pet imaging agents. The exposure is minimal but real and the risk vs. Benefit to the patient needs to be considered before ordering the study. Pregnant women should not have these studies and young women can have a very small but increased risk of breast cancer. ...Read moreSee 2 more doctor answers
nuclear stress: All tests have sensitivity and specificity and each lab has its own data. In the best labs these values for this test are >85% sens/spec., there are many technical factors. We choose tests by the information needed and the best test o get us what we need to know. ...Read moreSee 2 more doctor answers
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
Tomorrow i'm getting a nuclear stress test w cardiolite. Worried about side effects and reaction to the thallium or whatever they use. Should i worry?
Isotopes quite safe: Dyes are not used during nuclear stress tests. Trace radioactive isotopes are but there are no significant reactions to these minute doses used considering the thousands of tests done around the globe daily unless one has a history of being allergic to the thallium or cardiolite. ...Read moreSee 1 more doctor answer
Part of study: Wall motion a small part of myocardial perfusion study. Important findings of perfusion are related to ischemia and infarction of myocardial muscle. Spect (tomographic imaging) obrtains images in sagittal, coronal, and transaxial projections during stress and resting phase. 2 phases compared.. Technetium99m and thallium201 are isotopes. Also see cardiac chamber size and cardiac ejection fraction. ...Read more
Yes within reason. : The caffeine does not affect the nuclear tracer or the dobutamine. However, most protocols want you to have not eaten or drank for 8 hours. Additionally, in my lab we withhold caffeine from all stress test patients because some of them will need to be converted to other types of stress that can be affected by caffeine. This way all options are available while the patient is present. ...Read moreSee 2 more doctor answers
What are the primary differences in a CT scan of heart and a nuclear stress test? Would one make more sense looking for blockages?
CARDIAC IMAGING: A CT reveals anatomy with some limitation if heavy calcium is present & scanner technology dependent,A nuclear stress depends on the isotope (TCc vs Thallium vs one of the PET agents) reveals detailed information on function,often the 2 modalities are complementary and necessary for appropriate diagnosis and treatment/prognostication ...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
