Left ventricular diastolic function and atrial sphericity parameters were studied in 503 healthy Chinese adults. Men showed significantly different values in parameters such as LACI (0.19 vs 0.20) and LASI (0.52 vs 0.59) compared to women. These findings are important for standardized interpretation of cardiac magnetic resonance parameters in clinical practice

The cardiac diffusion tensor imaging (cDTI) technique with up to 6th order motion compensation was studied. The results show that 4th order compensation is necessary for successful diastolic acquisitions, with mean diffusivity values of (1.73 ± 0.19) × 10-3mm2∕s. This enables reliable quantification of myocardial microstructural changes between systole and diastole, a step towards clinical translation of dynamic cDTI.

In 49 patients with dilated cardiomyopathy and 23 controls, a non-contrast CMR technique showed lower myocardial oxygen extraction fraction (50.3% vs 57.6%) and lower mechano-energetic efficiency (22.9% vs 46.0%), with higher total oxygen consumption. Efficiency correlated with LVEF and global longitudinal strain. Feasibility study.

The feasibility of real-time cardiac magnetic resonance (CMR) for ventricular quantification in arrhythmic patients was studied. The results showed that the technique can reveal functional heterogeneity in patients with premature ventricular contractions (PVC), with broader and sometimes bimodal ejection fraction (EF) distributions. This may be important in clinical practice to improve the evaluation of cardiac function in arrhythmic patients.
