[PET-CT in the oncological translational platforms].

Area of Science:

• Oncology
• Radiology
• Biomedical Engineering

Background:

• Conventional cancer therapy evaluation relies on tumor size reduction, a late indicator of treatment efficacy.
• This traditional method can delay confirmation of therapeutic success for months.

Discussion:

• Molecular imaging, utilizing advanced radiotracers and techniques like Positron Emission Tomography (PET) and PET-CT, enables early assessment of treatment response.
• These methods can detect therapeutic effects within days of treatment initiation, significantly accelerating the evaluation process.

Key Insights:

• Molecular imaging provides a diverse range of biological information, including metabolism, cellular proliferation, DNA replication, and angiogenesis.
• Radiotracers can assess critical cellular processes such as protein synthesis, amino acid transport, hypoxia, and apoptosis.

Outlook:

• The development of novel imaging biomarkers and radiotracers is revolutionizing preclinical and clinical cancer research.
• Molecular imaging is poised to transform drug development by providing rapid, quantitative insights into therapeutic efficacy.
