TE
Also written as: TE — echo time
Echo time - the interval between radiofrequency pulse and signal readout in MRI sequences.
Full Definition
Echo time (TE) represents the time interval between the application of a radiofrequency pulse and the collection of the echo signal in MRI sequences. This parameter directly influences image contrast, with shorter TE values producing T1-weighted images and longer TE values emphasizing T2 weighting. Editors must distinguish TE from TR (repetition time) in technical documentation.
Usage
Usage note: Always capitalize when used as abbreviation; lowercase when spelled out.
In Context
- "The T2-weighted images were acquired with a TE of 85 ms." — MRI protocol documentation
- "Optimal TE selection depends on the target tissue contrast requirements." — Technical report
