Positron emission tomography (PET) is a vital in vivo molecular imaging tool for drug development and disease research. This technology provides high-quality data for molecular diagnosis, drug efficacy, and safety assessments.

Area of Science:

In vivo molecular imaging
Positron Emission Tomography (PET) imaging

Context:

PET is a preferred modality in drug development and pathophysiological science due to its high sensitivity, resolution, and broad target molecule spectrum.
Current advancements in PET molecular probes, instrumentation (e.g., microPET), and quantitative analysis methods are discussed.

Purpose:

To review the current status of PET molecular imaging technologies.
To highlight the applications of in vivo molecular imaging in drug development and clinical research.

Summary:

PET imaging offers critical insights for molecular diagnosis, etiological studies, disease marker tracking, pharmacokinetics/pharmacodynamics, personalized medicine (SNP-based dosing), adverse effect evaluation, and drug candidate assessment.
The establishment of an All-Japan research network in 2005 aims to foster international and multidisciplinary collaboration in in vivo molecular imaging.
