Review Questions

• How does in vivo spectroscopy differ from traditional ex vivo techniques in studying biological systems?
  • In vivo spectroscopy is performed on living organisms without the need for surgical procedures, allowing for the study of dynamic biological processes in real-time. In contrast, ex vivo techniques involve the extraction of tissues or cells from an organism, which may alter their natural state and limit the understanding of how these systems function under physiological conditions. The ability to observe changes in metabolic activities and biochemical environments live makes in vivo methods particularly valuable.
• Discuss the importance of using Magnetic Resonance Spectroscopy (MRS) within the context of in vivo spectroscopy applications.
  • Magnetic Resonance Spectroscopy (MRS) is a vital tool within in vivo spectroscopy as it provides detailed information about the metabolic profile of living tissues. By analyzing specific metabolites like lactate or choline, MRS can reveal insights into disease states such as tumors or neurodegenerative disorders. This capability enables clinicians and researchers to monitor disease progression, evaluate treatment responses, and tailor therapies based on metabolic changes observed through MRS analysis.
