Abstract: | Fluorescent X‐ray computed tomography (FXCT) enables visualization of myocardial fatty acid metabolism by using non‐radio‐iodinated I‐5‐(p‐iodophenyl)‐3‐(R,S)‐methylpentadecanoice acid (BMIPP). In this experiment, age‐dependent myocardial metabolic impairment was successfully imaged and analyzed quantitatively in J2N‐k cardiomyopathic hamster using FXCT. |
