- @type:
- 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.

https://openminds.om-i.org/instances/MRIPulseSequence/fastLowAngleShotPulseSequence
- @type:
- definition:
A gradient echo pulse sequence that combines a low-flip angle radio-frequency excitation of the nuclear magnetic resonance signal (recorded as a spatially encoded gradient echo) with a short repetition time.

- @type:
- definition:
A special inversion recovery pulse sequence where the inversion time is adjusted such that at equilibrium there is no net transverse magnetization of fluid in order to null the signal from fluid in the resulting image.

- @id:
https://openminds.om-i.org/instances/MRIPulseSequence/gradientEchoPulseSequence
- @type:
- definition:
In magnetic resonance imaging, a ‘gradient-echo pulse sequence’ is a contrast generation technique that rapidly induces bulk changes in the spin magnetization of a sample by applying a series of carefully constructed pulses so that the change in the gradient of the magnetic field is maximized, trading contrast for speed (cf. [Hargreaves (2012)](https://doi.org/10.1002/jmri.23742)).

- definition:
In magnetic resonance imaging, a ‘spin echo pulse sequence’ is a contrast generation technique that induces bulk changes in the spin magnetization of a sample by applying sequential pulses of resonant electromagnetic waves at different angles (cf. [Fonseca (2013)](https://doi.org/10.5772/53693)).
