| "definition": "In magnetic resonance imaging, an 'echo-planar pulse sequence' is a contrasting technique where each radio frequency field (RF) excitation is followed by a train of gradient echoes with different spatial encoding allowing for very rapid scanning. [adapted from [wikipedia](https://en.wikipedia.org/wiki/Physics_of_magnetic_resonance_imaging#Echo-planar_imaging)]", | ||
| "definition": "A magnetic resonance image pulse sequence that is composed of multiple echoes at different phase steps (often collected blocks of 64 or 128 phase steps), which are acquired using rephasing gradients where rephasing is achieved by rapidly reversing the readout or frequency-encoding gradient.", |

There was a problem hiding this comment.
It would be "an MR image", but "a magnetic resonance image".
(The letter "M" is pronounced "em", which starts with a vowel, so we use "an". The word "magnetic" starts with the sound "m", a consonant, and so we use "a")

Decided during offline meeting with @tgbugs, @Raphael-Gazzotti, @spieschnik and @Peyman-N that pulse sequences are not "weighted". Therefore all the pulse sequences in this PR should be updated (i.e., remove "weighted" from their names). |
