Positron emission tomography (PET) enables non-invasive molecular imaging in vivo. This technique allows detailed analysis of biological processes, aiding in disease phenotyping and therapeutic target identification.

Area of Science:

  • Molecular imaging
  • In vivo studies
  • Radiochemistry

Background:

  • Positron emission tomography (PET) provides non-invasive assessment of physiological, metabolic, and molecular processes.
  • Advances in detector technology have significantly improved PET spatial resolution to 1-2 mm, enabling small animal research.
  • Developments in radiochemistry and tracer technology allow analysis of gene expression and function.

Purpose of the Study:

  • To review the potential impact of molecular imaging by PET in neuroscience research.
  • Focus on applications in neurodegeneration and neuro-oncology.
  • Highlight the role of PET in characterizing animal models and identifying therapeutic targets.

Main Methods:

  • Utilizing advances in PET detector technology for high spatial resolution.
