Abstract

Introduction

In vivo imaging enables researchers to view biological processes at the molecular level. In vivo molecular imaging techniques have important implications for drug discovery and development because they aid in validating drug targets and in studying the biodistribution, target binding, clinical effects, and toxicity of drug candidates.

The development of in vivo molecular imaging techniques has important implications for drug discovery and development. How will pharmaceutical companies use this valuable information to accelerate their drug development process? Which imaging companies are the major players in this fi eld?

The FDA has introduced a new exploratory investigational new drug (eIND) mechanism that encourages companies to use imaging techniques during early-stage microdosing studies. How can pharmaceutical companies best capitalize on this new mechanism? Which imaging technologies are likely to see increased use as the result of eIND? The high cost of in vivo molecular imaging poses a signifi cant barrier to its widespread adoption. Will pharmaceutical and biotech companies decide to invest in these technologies despite the cost or will they seek other options?

The development of combined PET-MRI instrumentation will be a major breakthrough. How close to market are these powerful new tools? What new benefi ts will they offer?
