What advantages does positron emission tomography offer as a nuclear medicine tool?
Wiki User
∙ 13y ago
It is useful in the diagnosis, staging, and treatment of cancer because it provides information that cannot be obtained by other techniques such as computed tomography and magnetic resonance imaging.

How do medicine use isotopes?
- treatment by irradiation in cancers- scintigraphy- source in positron emission tomography- tracers
What is the use of arsenic 74?
Arsenic 74 can be used as a positron emitter in PET - Positron Emission Tomography, the scope is to identify tumors.
What is a phantom study?
It's an analysis used to develop a reliable quantitative data processing protocol for 3D PET(positron Emission Tomography) brain scanning for conditions typically encountered in FDG(Fluorodeoxyglucose) and neurureceptor brain imaging.
What is the difference in Oxygen-15 Positron Emission Tomography and 18-flourodeoxyglucose Positron Emission Tomography in terms of results in blood flow studies?
The difference is one between an cumulative signal vs a transient signal. Oxygen uptake reflects metabolic activity in the neurons. Areas of the brain that participate in a task will be preferentially marked by the tracer, but that signal will dissipate fairly quickly as the oxygen leaves the cell as carbon dioxide. The FDG-PET-CT is a cumulative signal as the active tissue will have an increased glucose transport into the neurons, but as the glucose is cleaved inside the neuron to supply metabolic needs the tracer part of the molecule stays inside the active neurons. So since most of the brain is active at some level this results in a background staining and a poor signal to noise ratio.
What are the ideal properties of a radioactive isotope used as a medical tracer?
Positron Emission, Metabolic Activity, Detection, "short" physical half-life
What are the advantages of Positron emission tomography?
PET scans can see inside the brain

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 PET stand for brain scan?
Positron Emission Tomography
What does the medical abbreviation PET mean?
Positron Emission Tomography
What is positron emission tomography used to diagnose?
Positron Emission Tomography (PET) scans are used in hospital mainly to detect cancers, especially cancers that have metastasised or spread into surrounding tissue.
What test do you have done to see if you had a stroke?
positron emission tomography (PET)
Technique that measures the levels of activity of different areas of the brain by tracing their consumption of a radioactive form of glucose?
This technique is known as positron emission tomography (PET) scan.
Positron-emission tomography forms images of body tissues this is known as what?
PET scan
