Quantification of Mouse Heart Left Ventricular Function, Myocardial Strain, and Hemodynamic Forces by Cardiovascular Magnetic Resonance Imaging

Executive Industry Relevance

Quantitative cardiovascular magnetic resonance imaging (CMR) in mouse models enables high-fidelity assessment of left ventricular function, myocardial strain, and hemodynamic forces, supporting early discovery and mechanistic de-risking in cardiovascular drug development. The protocol's ability to deliver comprehensive, non-invasive cardiac metrics from a single imaging session enhances predictive confidence and translational continuity across preclinical research. These capabilities are critical for portfolio triage and risk-adjusted advancement of cardiovascular therapeutic candidates.
