Recommendation for Cardiac Magnetic Resonance Imaging-Based Phenotypic Study: Imaging Part

Area of Science:

• Cardiovascular Imaging
• Population Health
• Biomarker Discovery

Background:

• Cardiac magnetic resonance (CMR) imaging offers vital biomarkers for early cardiovascular disease diagnosis and phenome-wide association studies.
• Operational complexity and technical variability limit CMR's use in large cohort studies.
• Current guidelines primarily address clinical diagnosis, not basic research needs.

Purpose of the Study:

• To establish a recommendation for CMR-based phenotype measurements tailored for cohort studies.
• To standardize quantitative phenotyping from CMR data in research settings.
• To facilitate broader application of CMR in large-scale population research.

Main Methods:

• Categorization of CMR imaging sequences based on phenotype importance and universality.
• Inclusion of acquisition time and measurement repeatability in sequence categorization.
• Focus on quantitative measurement of numerous phenotypes from CMR data.

Main Results:

• A structured recommendation for CMR sequence selection in cohort studies.
• Prioritization of sequences yielding important and universally measurable phenotypes.
• Consideration of practical aspects like scan time and reproducibility.

Conclusions:

• Standardized CMR protocols are essential for robust large cohort studies.
• This recommendation facilitates quantitative phenotyping for cardiovascular research.
• The proposed framework aims to increase CMR utilization in population-based studies.
