Short axis diastolic views showing cardiac motion artifacts when using ECG gating. Short axis diastolic views obtained from breath-held apex-to-base 2D CINE FLASH acquisitions using (top) vector ECG, (middle)ACT and POX (bottom) gating. In this subject (subject 2) vector ECG triggered 2D CINE FLASH imaging was prone to severe cardiac motion artifacts if R-wave mis-registration occurred. Images suffering from cardiac motion induced blurring are marked with grey bars. Acoustic triggering and POX provided image quality free of interferences from cardiac motion effects.
