Nuclear Perfusion Imaging
I've had nuclear perfusion imaging done. I ws advised to wait 6 wks.Is it ok to get pregnant after 6 weeks? Is there any risk of having abnormal kids?
Normal risk: 6 weeks is plenty of time for the body to clear the radiation you were exposed to. There is no increased risk of birth defects after the 6 weeks, but remember, there are always risks, even when one has not been exposed to radiation. If you have specific reasons for fearing birth defects, talk to mfm (maternal -fetal-medicine) doctor prior to conception and make sure to take your folate (folic acid) vitamins. ...Read more
Yes: There are no contraindications to intercourse after a nuclear stress test in terms of radioactivity. However if u are using a drug like Viagra (sildenafil) , it causes vasodilation of blood vessels , which when combined with the vasodilator in the stress portion of the nuclear scan can lower you blood pressure. So I would avoid intercouse for 24 Hrs after a pharmacological stress test. ...Read moreSee 1 more doctor answer
Well...: Since you had a cardiac nuclear scan, I assume your doctors were looking for coronary artery disease. You seem to be a smoker, which makes artery disease worse. So smoking is not a good thing for you, and you should try to stop. Having said that, you are probably not in any more immediate risk for heart problem for smoking after the nuclear exam. Long term risks are greater with smoking. ...Read moreSee 2 more doctor answers
Coronary Blood flow: Cardiac perfusion imaging is typically obtained to evaluate a pateint's coronary blood flow. This assesses the blood supply to the heart muscle, which is delivered through relatively small arteries around the heart called the coronary arteries. If the test is normal, it suggests that there is no significant CAD (coronary artery disease). If abnormal, CAD may be present. ...Read moreSee 2 more doctor answers
I was diagnosed with severe ischaemia from myocardial perfusion imaging. What are the procedures or treatments do I need to undergo to treat this?
Coronary Angiogram: Your cardiologist would probably want you to have a coronary angio to see if there are blockages or narrowings of the coronary (heart) arteries. Such lesions may be treated by angioplasty/stenting or bypass surgery. Not all coronary artery lesions are amenable to such treatment and may require medical therapy. ...Read moreSee 1 more doctor answer
Father's stress text revealed abnormal myocardial perfusion imaging due to sm area of mild ischemia in the apex. What does this mean?
Test result: If I presume your Dad is the 87y/o person listed on this then the test result has good implications. The gross implication is that there is coronary artery disease present and it isn't producing a lot of ischemia. In an 87y/o without symptoms or minor symptoms, medical therapy is appropriate. ...Read more
What does this mean: myocardial perfusion imaging adversely affected by soft breast tissue attenuation
Imaging Artifact: Soft tissue attenuation in the breast is a common artifact in myocardial perfusion imaging. It may artifactually affect the depiction of activity in the myocardial wall. If perfusion defect is seen on both stress & rest images and normal wall motion & wall thickness shown on ecg-gated spect then apparent fixed defect is an artifact of attenuation instead of an area of myocardial infarction. ...Read more
What this means?
Myocardial perfusion imaging with Tc-99m Sestamibi after exercise
revealed no scintigraphic evidence of hemodynamically significant
ischemia. Medium-sized, mid to basal inferior wall
mild-to-moderate mostly fixed perfusion deficit, excep
Stress test: A stress test with myocardial perfusion imaging is a way of detecting whether the heart muscle is getting insufficient blood supply because of coronary artery disease. It can be normal even with lots of coronary plaque, because it only detects severe narrowings. If there is a "fixed" perfusion defect that generally suggests a scar in the heart muscle from prior heart attack. Need more info. ...Read moreSee 2 more doctor answers
Stress Test: That uses a radioactive tracer to evaluate blood flow in the coronary arteries. Images are taken at peak exercise and at rest . These images are able to compare blood flow to the heart in specific territories supplied by each coronary artery and any flow disparity would be consistent with a potential blockage in that artery. ...Read more
