Why would a nuclear stress test be ordered?
The test is done to see if your heart muscle is getting enough blood flow and oxygen when it is working hard (under stress). Your provider may order this test to find out: How well a treatment (medicines, angioplasty, or heart surgery) is working. If you are at high risk for heart disease or complications.
What are the after effects of a nuclear stress test?
Possible complications and side effects include:
- allergic reaction to the dye.
- abnormal heart rhythms, or arrhythmias.
- fall in blood pressure during or after exercise, possibly leading to dizziness or faintness.
- chest pain.
- nausea.
- trembling.
- headache.
- flushing.
What medication is used for nuclear stress test?
Lexiscan or Adenoscan are administered by intravenous injection during a cardiac nuclear stress test to patients who cannot adequately exercise. These drugs dilate the coronary arteries and increase blood flow so that coronary artery obstructions can be identified.
Does a nuclear stress test show blockages?
The nuclear stress test shows how blood is flowing to your heart. The test can find blockages and identify damage from a prior heart attack.
Why am I so tired after a nuclear stress test?
Once you have exercised as much as you can, we will give you a second injection of the tracer so we can see the stress blood flow to your heart muscle. It is normal to feel tired, short of breath, heaviness of the legs while exercising.
Can nuclear medicine make you sick?
Are there side effects to nuclear medicine exams? Very few people experience side effects from a nuclear medicine exam. Allergic reactions are extremely rare. Any adverse reactions are usually mild, pass quickly, and need little or no medical treatment.
What is a drawback of using nuclear medicine?
What are the limitations of General Nuclear Medicine? Nuclear medicine procedures can be time consuming. It can take several hours to days for the radiotracer to accumulate in the area of interest. Plus, imaging may take up to several hours to perform.
What does nuclear medicine do to your body?
Nuclear medicine uses radioactive material inside the body to see how organs or tissue are functioning (for diagnosis) or to target and destroy damaged or diseased organs or tissue (for treatment). Images of the body show where and how the tracer is absorbed.
Does nuclear medicine make you tired?

What happens if you can’t complete a stress test?
If you have trouble completing the stress test in a specified period of time, it may mean there is reduced blood flow to your heart. Reduced blood flow can be caused by several different heart conditions, some of which are very serious.
Which is better echocardiogram or nuclear stress test?
Although stress echocardiography may have comparable ability to detect coronary artery disease, current data suggest that stress echocardiography detects significantly less jeopardized viable myocardium than stress nuclear myocardial perfusion imaging and consequently fewer patients at risk for cardiac events.
What medications should not be taken before a stress test?
HOLD 24 HOURS PRIOR TO TESTING: CAFFEINE/XANTHINE MEDICINES
- Theophylline (Theo-24, Theo-dur, Uniphyl, Slo-phyllin, Slo-Bid, Aerolate)
- Trental (Pentoxifylline)
- Excedrin, Anacin, Goody Powders.
- No Doz, Vivarin.
- Midol, Diurex.
- Fiorinal, Fioricet, Esgic (Butalbital combination medicines)
What are the negative effects of nuclear medicine?
There are no known long-term adverse effects from such low-dose exposure. Some potential side effects that might occur include: Bleeding, soreness or swelling may develop at the injection site and allergic reactions to the radiopharmaceutical may occur, but are extremely rare.
What is the best treatment for a DCIS?
If the DCIS is hormone receptor-positive (estrogen or progesterone), treatment with tamoxifen (for any woman) or an aromatase inhibitor, such as exemestane or anastrozole, (for women past menopause) for 5 years after surgery can lower the risk of another DCIS or invasive cancer developing in either breast.
Is imaging useful in the diagnosis of high-grade DCIS?
Research has extensively evaluated mammographic and MRI features of high-grade DCIS, and its appearances are well documented. Unfortunately, imaging currently shows little prospective value in cases of pure high-grade DCIS beyond the ability to make the initial diagnosis.
What is the typical course of enhancement in DCIS lesions?
The majority of pure DCIS lesions have rapid initial phase of enhancement in up to 77% of cases. 46,48,50 The type of delayed enhancement is variably reported, but most commonly described as plateau or washout. Less often, DCIS lesions may demonstrate slow, progressive delayed enhancement ( Figure 5 ).
Is a mastectomy the best option for DCIS?
In most cases, a woman with DCIS can choose between breast-conserving surgery (BCS) and simple mastectomy. But sometimes, if DCIS is throughout the breast, a mastectomy might be a better option.
