Molecular imaging visualizes molecular phenotypes using various systems and probes. Advancements require interdisciplinary collaboration, particularly from molecular and cellular biochemists.

Area of Science:

  • Biomedical imaging
  • Molecular biology

Background:

  • Molecular imaging visualizes molecular phenotypes in vivo.
  • It utilizes modalities like nuclear magnetic resonance, ultrasound, and optical imaging.
  • Contrast is generated using exogenous probes or transgenes.

Purpose of the Study:

  • To provide an overview of the field of molecular imaging.
  • To highlight current and emerging technologies.
  • To emphasize the need for interdisciplinary collaboration.

Main Methods:

  • Utilizes imaging systems (radionuclides, NMR, ultrasound, optical spectrum).
  • Employs exogenous probes (e.g., glucose analogs, receptor-targeted agents) and transgenes (reporter proteins, enzymes).
  • Incorporates in vivo assays for protein-protein interactions and mRNA expression.
