|Lights and shadows of Cardiac MR Imaging at 3T: quality assessment and comparison with 1.5T|
3T automatic Cardiac Volumes measurements had minor reproducibility (coefficient of variation (CV) was 30% for left cardiac sections and 61% for right sections); similar results for the 3T automatic LGE measurements (CV 39%) were observed.
T2-weighted images were inversely associated with BMI (One-way Anova, with post-hoc Tukey’s test p<0,0001)
Ratio between scar tissue SI and normal myocardium SI showed median value of 3,4 and 7,2 respectively at 1,5T and 3T; this difference was statistically significant (Wilcoxon rank sing test paired samples p=0,0005). Ratio between normal-perfusion and hypoperfusion myocardium SI at 3T was significantly higher than 1,5T, with median value respectively of 4,9 and 1,5 (Wilcoxon rank sing test paired samples p=0,004).
