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.
Yes. Most cardiologists are not trained to perform myocardial perfusion scans. The primary training for this procedure is done in nuclear medicine residencies. So, I would say that very frequently you are safer to have the scan done in a nuclear medicine clinic by a nuclear medicine specialist. Some cardiologists also specialize in this but not all.
It is never safe to. Although it is no more risky to smoke after a scan, it is never safe to smoke.
No. It is never "safe" to smoke! But there is no particularly increased risk due to the thallium perfusion scan. So go ahead and smoke but take serious measures to stop, soon.
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.
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.
Yes. Yes, usually a chemical stress with Adenosine, persantine, or Dipyridamole and thallium or sestamibi.
Yes. A pacemaker should not adversely affect the myocardial perfusion scan in any way and you should be confident going ahead with the scan. The scan will not harm the pacemaker.
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.
Probably not. In most clinics, you will need to stay still for 20 to 30 minutes while being scanned. If unable to do this, you may want to investigate other imaging tests such as stress echo or cardiac ct.
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..
Yes. Lots of people who have had a cataract operation have undergone myocardial perfusion imaging without any difficulties whatsoever.
Certainly. You might be able to see the results better too!
Yes. You can drive home unless you are administered a medication for relaxation during the test as is sometimes necessary for people with severe claustrophobia. However, this is very, very rare because nuclear cameras are so open. Nearly 100% of the people who get a myocardial perfusion scan can drive home safely after the test.
Yes. No sedatives or anesthesia is used for myocardial scans. Isotopes that selectively go to heart muscle are used. These radio pharmaceuticals do not have any effect that would prevent driving home. If test includes physical stress, patient will recover to normal state before leaving department. Cardiologist is continually monitoring heart beat, blood pressure, etc.
Perfusion scans. The main risks to these studies relate to the exercise stress used and to the radiation exposure. In general both are very well controlled and the complications and negative outcomes to these studies are very few and uncommon in good labs. The commonest side effects are with Persantine and Adenosine used to simulate exercise. Regadenoson a newer agent has few side effects.
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.
