What else can I help you with?
What are the diagnostic tests for myocardial ischemia?
Diagnostic tests include: resting, exercise, or ambulatory electrocardiograms; scintigraphic studies; echocardiography; coronary angiography; and rarely positron emission tomography.
What is a SPECT scan?
Single photon emission tomography
What IS the difference between cat and pet scan?
The difference is in the type of radiation used to form the image. A Computed Axial Tomography (CAT) scan can use any type of radiation to create the image, the specific type is not specified in the name, but most often uses X-rays; but a Positron Emission Tomography (PET) scan specifically uses positrons as the radiation form. A third type, Magnetic Resonance Imaging (MRI) uses the miniscule magnetic fields of naturally occurring compounds within the human body to create its images.
Why don't positrons annihilate the electrons in the same atom when they're released?
The positron released from an atomic nucleus in positron emission (or beta plus decay) appears with high kinetic energy. It's moving very quickly, and because it is, it has an extremely low probability of actually interacting with that atom's electrons in mutual annihilation. That positron will undergo some scattering events to dump energy, and only then will the probability of it being able to actually "combine" with an electron increase to the point where it will actually do so.
What do computed tomography scans do?
CT scans are used to image a wide variety of body structures and internal organs.
Which imagining system combines tomography with radionuclide tracers to produce enhanced images of selected body organs or areas?
positron-emission tomography(PET Scan)
Which imaging system combines tomography with radionuclide tracers?
positron emission tomography
What does the medical abbreviation PET mean?
Positron Emission Tomography
What test do you have done to see if you had a stroke?
positron emission tomography (PET)
What diagnostic procedure uses positive radionuclides to reconstruct brain sections?
Positron Emission Tomography (PET) is a diagnostic procedure that uses positive radionuclides to reconstruct brain sections. By tracking the positron-emitting tracer molecules, PET can create detailed images of brain metabolism and function.
Technique that measures the levels of activity of different areas of the brain by tracing their consumption of a radioactive form of glucose?
The technique is called positron emission tomography (PET). It involves injecting a radioactive form of glucose into the bloodstream, which is then taken up by active brain regions. The scanner detects the emitted positrons to create a map of brain activity.
What method of studying the brain involves the insertion of radioactive glucose into a vein?
PET - Positron Emission Tomography
How do medicine use isotopes?
- treatment by irradiation in cancers- scintigraphy- source in positron emission tomography- tracers
What is positron emission tomography used to diagnose?
Positron emission tomography (PET) is used to diagnose a variety of medical conditions, including cancer, heart disease, and neurological disorders such as Alzheimer's disease and epilepsy. It helps visualize and evaluate the activity of organs and tissues in the body based on the detection of radioactive tracers.
Which imaging system combines tomography with radionuclide tracers to produce enhanced images of selected body organs of areas?
positron-emission tomography(PET Scan)
Is a PET a laboratory procedure?
PET (Positron Emission Tomography) is a very modern and expensive medical imaging technique.
What staging tests assist in diagnosis of esophageal cancer?
computed tomography (CT scans ); thorascopic and laparoscopic examinations of the chest and abdomen; and positron emission tomography (PET)
