Skin irritation. I assume you are talking about an IV cannula used to administer the tracer and adenosine. The side-effects are the same as they would be for anyone else getting a cannula: bruising and skin irritation being most common. Generally, the IV cannula itself, properly placed, causes no side-effects, and the primary side-effect is bruising from missed attempts trying to get the IV started.
Clarify. I am not sure what is meant by a canula in this context.
None. Since you are getting radioactive substances you shouldn't be pregnant or even hold an infant in you lap for 24 hours after the test. For this reason I avoid this test in women in the reproductive years if I can.
None. There are no common side-effects from the radioisotope. There have been very rare reports of allergy. There is a theoretical, but unproven risk of the radiation inducing a cancer 10 to 20 years later. There also is a theoretical, but unproven risk of radiation myocarditis. The radiation exposure of 1 rem (about 10 msv) has not been shown to be harmful. See http://sgoti. Ws/qmhwh7.
Complete imaging. The heart is a 3 dimensional structure and the images are 2 dimensional. To completely visualize the entire heart, you need more than one view. Hard to fully describe the moon without flying around to the back side.
The diaphragm. The position of the diaphragm can change depending upon whether you are lying down prone or supine. Scanning from both directions is sometimes used to minimize interference from the diaphragm when imaging the heart.
I accidently spent 30 minutes with a patient during a myocardial perfusion scan while I am 3 weeks pregnant. Will it cause problems for my baby?
No. I work in a cardiac cath lab and my nurse was pregnanat and wore a badge outside her lead apron. It received essentially zero radiation despite hours and hours of exposure. The key is the inverse square law. The radiation drops off very quickly as you move inches away from the source (the patient's bloodstream). You have had a negligible exposure - you get more on a sunny day!
Shouldn't. There is no good evidence that this exposure would cause any harm at all to the fetus. But always keep in mind that the spontaneous miscarriage rate is about 15%. The 30 minute exposure described would not increase this rate of miscarriage.
Not really. Diagnostic imaging radiation is very low and not likely to cause any problems with your pregnancy. Follow up with your ob/gyn as usual.
Radiation... Depending on what radiotracer is used, you will be exposed to a small amount of radiation but the benefits of the test should outweigh the risks. Are you having pharmacologic or exercise test? Some of the pharmacologic agents can cause some side effects such as bronchoconstriction but a medication called aminophylline can usually be administered to reverse the side effects.
Iv just had a stress myocardial perfusion scan to see if blood is pumping around my heart properly, are there any side affects after having this?
Should not. It's a safe test. There should not be any side effects.
Radiation... Depending on what radiotracer is used, you will be exposed to a small amount of radiation but the benefits of the test should outweigh the risks. Was it pharmacologic or exercise test? Some of the pharmacologic agents can cause some side effects immediately after stress such as bronchoconstriction but a medication called aminophylline can usually be administered to reverse the side effects.
Sometimes. Yes in some centers they are read the same day, but most take longer.
Sometimes. It is possible but more often you will get your results the next business day.
Yes, but... Yes if you are more than 6 feet away from them for the first 24 hours. After that no restrictions.
Yes. If you are released from the clinic, you will meet federal and state regulations designed to make it safe to be around other people, including children.
Small exposure. The doses of radiopharmaceuticals used for these scans are usually relatively low dose. However thallium (half life 2.7 days) gives more radiation than technetium sestamibi (half life 6 hrs).Radiation reduction depends mainly on two factors time and distance. If you do not stay close to child for prolonged time then radiation exposure is reduced. Growing children more sensitive to radiation.
Yes. Yes unless they use different medicine.
Imaging myocardium. Myocardial perfusion scan is usually injection of radioactive tracer either thallium 201 or tc99m sestamibi. Imaging usually consists of stress, exercise on treadmill or drug induced stress, and then resting phases. Both are imaged and compared looking for areas of permanent damage, infarction, or areas of ischemia, reversible defects in perfusion.
