What could cause difficulties with a cardiac perfusion scan?

What could cause difficulties with a cardiac perfusion scan?

Movement: Am unclear as to your question, but if i understand right, then moving during the scan would cause problems. Not removing a bra containing wires could cause problems. Severe claustrophobia can also cause problems. ...Read more

What is the purpose of a myocardial perfusion scan?

Nuclear stress test: This is a specialized form of stress test used to confirm the presence of coronary artery disease in patients suspected of having this problem. It uses a low-level nuclear tracer to assess blood flow to the heart muscle before and after exercise-induced stress. In patients who cannot exercise, other pharmacologic means can be used such as adenosine, lexiscan, persantine, or dobutamine. ...Read more

What is the function of a myocardial perfusion scan?

What is the function of a myocardial perfusion scan?

Blood flow to heart: It shows blood flow to the heart. It can show old scar of a heart attack or heart muscle that is not getting enough blood , which could mean a future heart attack. ...Read more

Can I eat food before having myocardial perfusion scan?

Can I eat food before having myocardial perfusion scan?

No: No because the blood flow to stomach increased and it makes the image less accurate. ...Read more

What is the definition or description of: myocardial perfusion scan with exercise?

What is the definition or description of: myocardial perfusion scan with exercise?

Cardiac Exam: Myocardial perfusion imaging looks at blood flow to the left ventricle. This is primarily accomplished using nuclear techniques such as pet or spect using radiotracers such as tl-201, tc-99m, or n-13 ammonia. When it is done with exercise, the myocardial perfusion scan shows blood flow during exercise, and usually compares that to perfusion at rest in order to evaluate for inducible ischemia. ...Read more

Why would someone be scanned both front side and back during the myocardial perfusion scan?

Why would someone be scanned both front side and back during the myocardial perfusion scan?

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. ...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

What is a pulmonary perfusion scan used for?

Blood clots : A blood clot that floats into the lung interferes with blood flow to that segment. A lung perfusion scan with will show a hole (no blood flow) behind the clot. ...Read more

Why would a pulmonary ventilation/perfusion scan be performed?

Pulmonary Embolism: The main reason to perform a pulmonary ventilation-perfusion (v-q) scan is to rule out the presence of a pulmonary embolus (commonly a blood clot). There are several forms of pulmonary thrombo-embolism, but the most common situation is one of sudden onset, leading to sob. Chronic thrombo-embolism leads to development of sob over a long period and it can also be diagnosed with a v-q scan. ...Read more

What is the function of a vent perfusion scan?

Dx Pulmonary Embolus: A ventillation perfusion lung scan is a nuclear test used to diagnose a blood clot to the lung or pulmonary embolus. Medication is injected into your vein and you also breath a medication into the lung to look for a mismatch on a nuclear imaging camera which would suggest a pulmonary embolus. ...Read more

What is a ventilation-perfusion scan?

What is a ventilation-perfusion scan?

Radiological test: A ventilation-perfusion (v/q) scan is a specialized radiological lung test comparing mismatches between any part of your lung that still exchanges oxygen (affected in COPD e.g.) and any part that is not receiving blood flow. This is done through radio-tracers. A mismatch means there is a clot in that part of the lung hindering blood flow. Diseases & surgery of the lung complicate interpretation. ...Read more

What are the risks in having a myocardial perfusion scan?

What are the risks in having a myocardial perfusion scan?

Stress associated : A myocardial perfusion scan is performed in two steps. One injection of a radiotracer at rest and another at stress ( either treadmill or pharmacological stress test with adenosine, regadenoson, dobutamine, dipyridamole). Only few skin reactions have been reported with the radiotracer injection. Risks are more associated with the stress used for the test such has angina, headache, nausea... ...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
