A novel self-gated 2D spiral CINE MRI method is proposed to assess coronary endothelial function (CEF) and was tested in healthy volunteers. Cardiac self-gating data were extracted from the k-space center and showed high correlation with simultaneously-recorded ECG. High coronary image quality and CEF measures, in good agreement with a standard ECG-triggered method, can now be obtained without the need for ECG.
