Could you have a myocardial perfusion scan after a cataract operation?

Could you have a myocardial perfusion scan after a cataract operation?

Yes: Modern day cataract surgery is minimally invasive and can even be done with just eye-drop (topical) anesthesia. While an implant (silicone or acrylic) is placed during the surgery, there are no restrictions on any future nuclear imaging, mri, ct scan etc.. ...Read more

Cataracts (Definition)

Occurs whent here is a clouding (or change in protein composition) of the normally clear lens (which is located behind the pupil and iris) inside the eye. Cataracts are most commonly due to aging, but can be congenital (born with it), due to trauma or uveitis (eye inflammation). Can be worsened by long-term topical steroid ...Read more

Could you have a myocardial perfusion scan if you suffer from myoclonic dystonia?

Could you have a myocardial perfusion scan if you suffer from myoclonic dystonia?

Stress test: It is paramount that the patient is completely still when undergoing myocardial perfusion scanning -- therefore if the myoclonic dystonia is well controlled then you could probably have the scan -- otherwise you have other option of stress and imaging modality. ...Read more

Is it safe to have a myocardial perfusion scan done without a cardiologist?

Is it safe to have a myocardial perfusion scan done without a cardiologist?

Probably: At some hospitals, physicians assistants are who is actually present during the study. As these tests usually involve some type of stressing of the heart, it is important that whoever is supervising the test has the knowledge to make the decision that the patient is stable and that it is safe.. In most cases, a cardiologist has had some input in that decision even if not there for the test. ...Read more

Can someone have a myocardial perfusion scan with a pacemaker?

Can someone have a myocardial perfusion scan with a pacemaker?

Yes: Yes, patients with implanted pacemakers have nuclear stress tests/myocardial perfusion scans. The EKG portion of the test will reflect the pacemaker (and likely a left bundle branch block) but reversible ischemia can still be detected in the scans. ...Read more

Could you tell me what is the purpose of a myocardial perfusion scan [nuclear test]?

Could you tell me what is the purpose of a myocardial perfusion scan [nuclear test]?

CAD: The purpose is to diagnose significant coronary artery disease (CAD). If the scan is positive for ischemic changes in the heart, then you will benefit from aggressive medical treatment, angiographic treatment, or surgery. If the scan is negative (and done properly), your risk for CAD or a significant injury such as a heart attack in the next few years is very low. ...Read more

Is it safe to be around kids after a myocardial perfusion scan?

Is it safe to be around kids after a myocardial perfusion scan?

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. ...Read more

Does a myocardial perfusion scan show blockage in the heart?

Does a myocardial perfusion scan show blockage in the heart?

Blood Perfusion: The angiogram shows anatomic blockage of coronary arteries. The myocardial perfusion scan shows blood flow to the heart. Blood flow can get past large blockages (shown on angiography) if there are enough small, collateral vessels present. ...Read more

Will a myocardial perfusion scan look at the arteries in your neck and head?

Will a myocardial perfusion scan look at the arteries in your neck and head?

Only heart: A cardiac perfusion scan measures the amount of blood supplied to your heart muscle. Radiotracers are injected intravenously and travel through blood to heart muscle. Indications for this study include chest pain, previous heart attack, heart surgery and coronary artery disease. Ultrasound, MRI , ct with contrast, arteriography, and brain scans address issues in head and neck. ...Read more

Are there any side affects after having a myocardial perfusion scan if so can you tell me please?

Are there any side affects after having a myocardial perfusion scan if so can you tell me please?

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. ...Read more

Can you tell me about the purpose of a myocardial perfusion scan [nuclear test]?

See blood flow: Myocardial perfusion studies show the pattern of blood flow (perfusion) to the tissue of the heart muscle. The radiotracer goes where the blood goes and this shows how well the tissue is nourished. It can be an indicator of blocked arteries when the perfusion pattern is abnormal. ...Read more

What are common side effects from the radioisotope in a myocardial perfusion scan?

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. ...Read more

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! ...Read more

How long following a myocardial perfusion scan should I wait before visiting a person with a pacemaker?

How long following a myocardial perfusion scan should I wait before visiting a person with a pacemaker?

Immediately: There are no contraindications to visiting a person with a pacemaker after you had a nuclear stress test. You can visit them anytime as the radiation does not effect the pacemaker. ...Read more

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

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 more
