AI Article Synopsis
- The study explored how real-time (RT) non-ECG triggered MRI can significantly reduce exam time while maintaining high reproducibility, especially compared to standard ECG-triggered methods.
- RT MRI showed a data acquisition time reduction of more than tenfold while yielding similar results, with only a slight overestimation of left ventricle mass.
- The RT method demonstrated low variability in results, making it a reliable option for patients who struggle with breath-holding or have arrhythmias.
Article Abstract
The increasing frequency of LV functional MRI studies demands for faster methods and for more comfort for the patient. We tested, whether real-time (RT) non ECG triggered MRI allows a considerable shortening of examination time in high reproducibility. RT and standard ECG-triggered breathhold cine MRI was acquired in 9 volunteers and 21 patients. Differences between both methods were assessed by Bland-Altman analyses including variability studies. Compared to standard cine MRI, RT decreased data acquisition time by more than the factor of ten. RT produced comparable results (e.g. EF in %: +0.67 [-5.63, 6.97]) except for a slight overestimation of LV mass. Interstudy and intraobserver variability of RT cine showed a low variability. Consequently, free-breathing RT cine proved to be a reliable and suitable tool for clinical routine and may be particularly relevant in patients with sub-optimal breath-holding ability and arrhythmia.
