- This is a fairly uncommon term, even within the medical and scientific community. This is partly due to the recency of the emergence of this effect, and partly because of how specific this type of MRI is, so many people may not know this term, even those who use MRI very frequently. The term is obscure and hard to understand, so it would likely only be used in a very formal setting such as a published paper or a presentation. It can be written with and without the dash.
Hyper-CEST
blending noun
an effect in MRI when hyperpolarized xenon is used that allows high detection at low concentrations
Etymology : HyperCEST stands for Hyperpolarized Xenon Chemical Exchange Saturation Transfer, so it is a unique case of initialism where the first letter is taken from the last four words, none from the second word, and then blended with a clipping from the first word. The technology appears to have been invented, and the term coined, in 2006 by researchers from Berkley. It is unclear how the word was created, though it is likely that the pronounceability of the acronym was considered when they were coming up with the name.
