The objective of this prospective observational study is to assess the clinical validity of a novel free-breathing cardiac cine MRI technique by comparing left ventricular ejection fraction (LVEF) measurements obtained with the conventional breath-hold cine against those acquired with the free-breathing cine in patients clinically indicated for cardiac MRI at Tohoku University Hospital. The primary endpoint is the difference in LVEF between the two methods.
Efficacy
Difference in left ventricular ejection fraction (LVEF) obtained by conventional breath-hold cardiac cine MRI versus free-breathing cardiac cine MRI.
1. Differences in cardiac volumetric and functional parameters
- Left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular cardiac output, left ventricular myocardial mass, right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), right ventricular cardiac output, left atrial maximum volume, left atrial minimum volume, right atrial maximum volume, and right atrial minimum volume obtained by conventional breath-hold versus free-breathing cine MRI.
2. Differences in myocardial deformation metrics
- Myocardial strain and strain rate measured with conventional breath-hold versus free-breathing cine MRI.
3. Difference in qualitative image quality
- Difference in the proportion of cine images rated as Grade 3 or higher on qualitative image quality scoring between the two methods.
4. Differences in quantitative image quality metrics
- Difference in quantitative measures of image quality (e.g., signal-to-noise ratio, contrast-to-noise ratio) between conventional breath-hold and free-breathing cine MRI.
5. Difference in acquisition time
- Difference in total cine image acquisition time between the two techniques.
6. Interobserver agreement
- Interobserver agreement (e.g., Cohen's kappa) for qualitative image quality grading.
7. Subgroup analysis of the primary outcome
- Analysis of the primary outcome (difference in LVEF) in patient subgroups stratified by age, sex, body mass index (BMI), respiratory rate, heart rate, and presence/absence of arrhythmia.
