Abstract: Metabolism underlies nearly every biological process, from neuronal signaling and muscle contraction to cancer progression and immune response. Despite its central role in health and disease, observing metabolic activity in real time within living organisms remains a fundamental scientific challenge. Magnetic resonance (MR), traditionally associated with structural imaging, provides a unique and non-invasive window into in vivo biochemistry by directly probing molecular spins and their interactions.
This talk presents an overview of real-time in vivo metabolic imaging using magnetic resonance techniques, with emphasis on magnetic resonance spectroscopic imaging (MRSI), hyperpolarized carbon-13 imaging, and deuterium metabolic imaging (DMI). The underlying spin physics, signal generation mechanisms, and fundamental sensitivity constraints are discussed. Through selected examples spanning glucose metabolism, energy pathways, and representative applications, the presentation highlights how advances in hardware, pulse sequence design, and AI-assisted signal processing are transforming MR from a static imaging modality into a powerful tool for functional and metabolic investigation of living systems.
