Figure 1From: Cardiovascular magnetic resonance artefactsSpin-echo and gradient-echo. a) Conventional spin-echo pulse sequence. b) Conventional gradient-echo pulse sequence. There are 5 different events shown: RF - radio-frequency pulses, Grd - readout gradient axis, Gpe - phase-encode gradient axis, Gss - slice-selection gradient axis, and signal - acquired echoes.Back to article page
