How are contrast ventriculography and radionuclide angiography different?

How are contrast ventriculography and radionuclide angiography different?

Ventrivculography: Both are different tests with different techniques. Contrast ventriculography is a cardiac catheterization procedures used to assess heart pumping function. Radionuclide angiography is a nujclear scan (muga scan) used to assess pumping function of the heart. Catheterization is an invasive procedure and muga scan is non-invasive procedure with minimal risk. ...Read more

Whats the difference between contrast ventriculography and radionuclide angiography?

Whats the difference between contrast ventriculography and radionuclide angiography?

X-ray vs radioactive: Contrast ventriculography uses x-ray contrast material, and rnvg uses a radioactive tracer. Acquisition time is shorter with x-ray compared to nuclear imaging. Both are great, but nuclear probably more accurate. ...Read more

What are the differences between contrast ventriculography and radionuclide angiography?

Imaging: Contrast ventriculography is using a contrast agent to image the ventricle(s) of the heart. It can be radiographic, ultrasonic or radionuclide imaging. Radionuclide angiography uses radioactive tracer to image the blood vessels and heart. ...Read more

What are the chances of surviving a nuclear blast?

What are the chances of surviving a nuclear blast?

Distance: At around five miles away, you will suffer third degree burns. Even at 20 miles away the heat can burn the skin off your body. The wind from the blast will reach as high as 600 miles per hour. ...Read more

Whats a nuclear medicine scan?

Whats a nuclear medicine scan?

A radiology test: A nuclear scan is a type of radiology study that involves getting injected (or taking orally) a small dose of radioactive tracer that can be imaged by nuclear medicine specific scanners. It is unique in that it measures the physiology of the specific tracer instead of a person's anatomy. Typically, the radioactivity dose used for these exams is minuscule and presents no/little risk. ...Read more

Could nuclear stress tests be false?

Could nuclear stress tests be false?

Yes...: Yes...Nuclear stress tests can have false positive results. There are different types of nuclear stress tests. There is treadmill vs. Pharmacologic and there is spect vs. Pet. There are also many different tracers such as thallium or technetium for spect and ammonia or rubidium for pet. Each type of test has its own possible pitfalls. Artifacts are often the case of false positive. ...Read more

What is adrenosine nuclear test preparation?

No caffeine 24 hrs: Among other things to withhold, caffeine is probably the most important as it negates the effect of adenosine, preventing any stress. Other common things are don't eat for at least 4 hours prior to the test, no chocolate, stop some medications. Call the testing office for their specific protocol. ...Read more

What are radioisotopes and nuclear medicine?

What are radioisotopes and nuclear medicine?

Functional imaging: Nuclear medicine is use of internal ionizing radiation in form of radioisotopes by intravenous injection, ingestion, catheterization of bladder or inhalation. Functional imaging is performed of skeleton, heart, brain, thyroid, liver, spleen kidneys, bladder, lymph system, gallbladder, etc. Gamma rays instead of xrays. Radiography and MRI are anatomic imaging. ...Read more
