Dual echo pulse sequence. a) Dual echo pulse sequence used to generate a positive contrast image (dephased echo) and a standard bSSFP contrast image (refocused echo) simultaneously. Example dephased and refocused images show a nitinol guidewire inserted transfermorally into the descending aorta of a Yorkshire swine. b) Variation of the slice refocusing moment as a percentage of the full refocusing moment used for image dephasing. c) The variable flip angle scheme used with linear k-space encoding.
