简介：
Overview
This method outlines the use of Quantum Micro-Computed Tomography (MicroCT) to assess cardiac morphology, function, perfusion, metabolism, and viability with iodinated contrast agent in mice with experimentally-induced myocardial ischemia. The technique provides a rapid, longitudinal, non-invasive evaluation of critical cardiac parameters.
