In this study we compared the accuracy of measurements for left ventricular function and volume in subjects using 2D balanced SSFP and novel 3D kat ARC sequences. Left ventricle ejection fraction (LVEF), end diastolic volume (EDV), and end systolic volume (ESV) measurements were obtained in patients and healthy volunteers. No significant differences in LV ejection fraction or volume measurements were observed between the two sequences, with 3D kat-ARC sequence generating LV measurements which were non-inferior to 2D SSFP. Consequently, this approach should enable substantial improvements in scanner time efficiency without sacrificing diagnostic accuracy.
