Is oxygen 15 stable?
Oxygen-15 is an isotope of oxygen, frequently used in positron emission tomography, or PET imaging. It is not stable.
What is an emission spectra used for?
The emission spectrum can be used to determine the composition of a material
Why are emission spectra called the fingerprints of the elements?
Because an emission spectrum is specific to an element.It can be used to identify the element
How could pcr be used to diagnose diseases or other medical conditions?
PCR itself cannot be used to diagnose a disease; it is only useful for amplifying a DNA sample. Molecular analysis can only be done with subsequent techniques, such as electrophoresis and DNA sequencing.
What are Frequencies of light emitted by an element called?
"Spectrogram" is a word used to describe the set of specific characteristic frequencies of light which are emitted by a given chemical element when it is sufficiently excited by heat or by some other means.Alternatively, a scientific technique known as "spectroscopy" can be used to identify the elements in some matter of unknown composition and also the emission spectra of molecules can be used in chemical analysis of substances.Because each element's emission spectrum is unique, the "emission spectrum" of a chemical element or chemical compound can be used to help identify what it is. The "emission spectrum" is the name given to the relative intensity of each frequency of electromagnetic radiation http://www.answers.com/topic/emission-spectrum by the element's atoms or a compound's molecules when they are returned to a ground state.
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 the technique that produces a picture of the brain activity levels in different parts of the brain?
Functional magnetic resonance imaging (fMRI), positron emission tomography (PET), electroencephalography (EEG), magnetoencephalography (MEG), and single photon emission computed tomography (SPECT) are used to investigate brain activity.
Is oxygen 15 stable?
Oxygen-15 is an isotope of oxygen, frequently used in positron emission tomography, or PET imaging. It is not stable.
What clinical tests are used in diagnosis of frontotemporal dementia?
functional imaging with single photon emission CT or positron emission tomography may be better at identifying FTD in its early stages, showing decreased blood flow to the frontal and temporal lobes.
For what purposes was positron emission tomography first used?
Physicians first used PET to study brain activity in neurological diseases and disorders including stroke, epilepsy, Alzheimer's disease, Parkinson's disease , and Huntington's disease
What tool is used in a hospital to look at blood flow in a brain?
Usually a PET scanner (positron emission tomography scanner) with radioactive glucose. Note: following this test you will be slightly radioactive for about 10 to 12 hours.
For what purposes is positron emission tomography most commonly used at present?
PET is now used to evaluate patients for these cancers: head and neck, lymphoma, melanoma, lung, colorectal, breast, and esophageal. PET also is used to evaluate heart muscle function
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.
Which imaging system combines tomography with radionuclide tracers to produce enhanced images of selceted body organs or areas?
The imaging system that combines tomography with radionuclide tracers to produce enhanced images of selected body organs or areas is call PET or positron emission tomography. These types of scans are most commonly used check for brain function, poor blood flow and cancer.
Is there personal protective equipment used for Positron Electron Tomography workers?
No, as the job presents no dangers to the people. In fact, a survey in America shows that a builder is 10 times more likely to get sick than a Positron Electron Tomography worker. Hope this helps you!
What does the medical abbreviation FDG mean?
FDG stands for fluorodeoxyglucose, which is a radioactive glucose analog used in positron emission tomography (PET) scans to visualize metabolically active tissues in the body.
Why need positron?
Positrons are used for 'PET', a medical imaging tomography technique. The positrons are produced in the radioactive decay of Sodium 22.
