Molecular imaging visualizes disease at the cellular level using nuclear medicine, MRI, and optical imaging. This technology enables early disease detection and drug screening by tracking gene expression in vivo.

Area of Science:

  • Molecular biology
  • Radiologic sciences
  • Medical imaging

Background:

  • Molecular imaging offers a novel approach to disease detection by focusing on cellular and genetic levels.
  • Advances in gene expression imaging show significant promise for early disease diagnosis.

Purpose of the Study:

  • To review current molecular imaging techniques for visualizing gene expression.
  • To explore the translation of in vitro gene expression assays into radiologic sciences.

Main Methods:

  • Review of nuclear medicine, magnetic resonance, and optical imaging modalities.
  • Analysis of in vitro assays for protein and gene expression.
  • Assessment of methods for in vivo application in radiologic sciences.
