Positron emission tomography (PET) is a vital tool for in vivo molecular imaging in disease research and drug development. Its high sensitivity and broad molecular targeting enable precise diagnostics and personalized medicine strategies.

Area of Science:

  • Molecular imaging, particularly Positron Emission Tomography (PET)
  • Pathophysiological science
  • Pharmacology and drug development

Context:

  • In vivo molecular imaging is crucial for understanding disease mechanisms and evaluating drug efficacy.
  • PET offers superior sensitivity, resolution, and molecular targeting capabilities compared to other modalities.
  • Advancements in imaging networks foster international and multidisciplinary collaboration.

Purpose:

  • To highlight the utility of in vivo molecular imaging, especially PET, in various scientific and clinical applications.
  • To showcase the potential of molecular imaging for diagnosis, disease monitoring, and personalized drug development.
  • To emphasize the role of imaging in understanding pharmacokinetics, pharmacodynamics, and adverse effects.

Summary:
