Correlation between CMR and TDI parameters. Spearman's rank test showed good positive correlations between CMR normalized peak volume sweep rates and TDI MA velocities in early-to-late diastolic ratios. CMR PSRE/PSRA correlated better with TDI lateral e′/a′ than it did with TDI septal e′/a′. However, PSRE/PSRA correlated best with the average e′/a′ of lateral and septal locations.
