missing definition/synonym of some of the techniques

[szafarnia]

Dear all,

The definition and/or synonym of the techniques listed below is/are not yet registered in OpenMIND. Could you please add the missing information to each one?

• positron emission tomography (PET)
• electroencephalography (EEG)
• Ultra-high-field magnetic resonance imaging (UHFMRI)  only the synonym is missing
• diffusion-weighted imaging (DWI)
• magnetic resonance spectroscopy (MRI)  only the synonym is missing
• functional magnetic resonance imaging (fMRI)
• high-field magnetic resonance imaging (HFMRI)

Many thanks.

Best, Sara

@spieschnik, lets have a look at these

@aeidi89 @spieschnik any update on providing definitions?

[spieschnik]

Positron emission tomography Definition: Functional imaging technique, that uses radioactive tracers to measure changes in physiological functions (https://en.wikipedia.org/wiki/Positron_emission_tomography). Interlex: http://uri.interlex.org/base/ilx_0739570 Synonyms: PET, PET scan

Electroencephalography Definition: Non-invasive technique to record an electrogram of the brain (https://en.wikipedia.org/wiki/Electroencephalography). Interlex: http://uri.interlex.org/base/ilx_0741211 Synonym: EEG

diffusion-weighted imaging definition: Magnetic resonance imaging technique that makes use of a specific set of pulse sequences and software to generate images from the resulting data using diffusion of water molecules as contrast. InterLex: http://uri.interlex.org/base/ilx_0103242 synonyms: DWI, dMRI, diffusion-weighted magnetic resonance imaging, diffusion MRI, diffusion-MRI

@spieschnik @tgbugs I would not have used "PET scan" as synonym for PET, because with scan I associate rather the data product that comes out of the technique. What about you?

[lzehl]

functional magnetic resonance imaging definition: Magnetic resonance imaging technique makes use of a specific pulse sequences and software to generate images from the resulting data using changes associated with blood flow as contrast. InterLex: http://uri.interlex.org/base/ilx_0741210 synonym: fMRI, functional MRI

[lzehl]

for the field strengths in MRI, I would suggest the following:

• low-field: smaller than 1.5T (excl 1.5T)
• medium-field: 1.5T - 3T (excl 3T)
• high-field: 3T - 7T (excl 7T)
• ultra-high-field: larger than 7T (incl 7T)
