Abstract
The purpose of this study was to assess whether accurate global leftventricular LV functional parameters can be obtained by analyzing every second shortaxis magnetic resonance imaging cine series instead of consecutive slices in order to reduce postprocessing time Forty patients were scanned on a 15 T MRIsystem Magnetom Sonata Siemens Medical Systems Erlangen Germany using a steadystate free precession SSFP sequence A stack of shortaxis cine series from above the mitral valve through the apex was acquired Postprocessing was started at the most basal slice of the left ventricle in which at least 50 of the circumference was myocardium Enddiastolic volume EDV endsystolic volume ESV stroke volume SV ejection fraction EF and LV mass LVM were calculated Data analysis was repeated but now only every second slice was analyzed Bland–Altman analysis showed slightly lower values for all LV parameters when only every second slice was analyzed ranging from 17 difference for EF limits of agreement −35 to 50 to 46 for SV limits of agreement −72 to 150 Analysis of every second slice for quantification of global LV function is timesaving and as accurate as analysis of consecutive slices
