Targeted Agents for Imaging and Therapy

Molecular Imaging allows the visualization of biological processesin vivo, offering new chances for healthcare with respect to early diagnosis and improved therapy. The new field of molecular imaging isboosted by more sensitive imaging systems and the emergence of targeted imaging agents that home in on molecules of interest. This chapter describes the principles of molecular imaging and the differentstrategies to design targeted agents. Each imaging modality offers certain strong points but also shortcomings, which impact targeted agent design and their potential area of application.
