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.
